Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-5 and 7-17 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites the limitation “the sterile barrier” in line 15. There is insufficient antecedent basis for this limitation in the claim. For examination purposes, the claimed “sterile barrier” in line 15 is herein interpreted as referring to the previously claimed “medical procedural barrier” in line 7. Clarification is required.
Claims 2-5 and 7-17 are also rejected under 35 U.S.C. 112(b) due to the dependency from independent claim 1.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1-2, 5, 7, 9, 11, 13-14, 16, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Miller et al. (US Patent No. 5,758,650 A, of record, with date of patent 06/02/1998, hereinafter Miller) in view of Halmann et al. (US 2015/0209003 A1, of record, with publication date 07/30/2015, hereinafter Halmann).
Regarding independent claim 1 and similarly independent claim 18, Miller discloses a medical ultrasound system (see, e.g., Fig. 1 with the corresponding disclosure), comprising:
an ultrasound probe (Fig. 1: ultrasound transducer probe 100) (see, e.g., Fig. 1, and Col. 3, lines 5-13, “In FIG. 1, an ultrasound transducer probe 100 is shown in place against the body 102 of a patient. As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown) that generate transmission and driving signals for the piezoelectric array (also not shown) in the probe. The array thereby generates an ultrasonic beam (illustrated in FIG. 1 as scan lines 106) that is focused into an interrogation region 108, that is, a region of interest in the patient's body”); and
an accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) including a housing (Fig. 1: main guide body 114 of needle guide 112 and comprising mounting arrangement 118) attached to the ultrasound probe (100), the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) configured to facilitate operational coupling between the ultrasound probe (100) and one or more optional accessories (Fig. 1: needle 110) (see, e.g., Fig. 1, and Col. 3, lines 5-13, “In FIG. 1, an ultrasound transducer probe 100 is shown in place against the body 102 of a patient. As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown) that generate transmission and driving signals for the piezoelectric array (also not shown) in the probe. The array thereby generates an ultrasonic beam (illustrated in FIG. 1 as scan lines 106) that is focused into an interrogation region 108, that is, a region of interest in the patient's body”, and Col. 3, lines 35-40, “The needle 110 is guided and secured by a needle guide, which is indicated generally as the guide 112. The main features of the guide 112 are a main guide body 114, a removable, exchangeable needle cap 116 that fits and is held onto the main body, and a mounting arrangement 118, which is attached to or is an integral portion of the main body 114”, and Col. 3, lines 53-57, “The mounting arrangement 118 preferably includes, for example, arms with protrusions (FIG. 2) that fit into respective indentations, recesses or grooves on either side of the probe 100, as well as in a side surface 130 of the probe, to fix the position of the needle guide relative to the probe”), wherein the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) is coupled with the ultrasound probe (100) across a medical procedural barrier (see, e.g., Col. 5, lines 10-25, “This preferred mounting arrangement is particularly advantageous in the common case in which the needle guide and needle are in the sterile field of the surgical procedure, but the ultrasound probe itself is not. In these cases, the ultrasound probe is typically covered by a sterile sheath, which is typically made of Latex or of some other flexible synthetic material. The needle guide is then mounted over the sheath. Using know[n] needle guide mounts, there is a tendency to subject the sheath to rolling and shearing stresses where the guide contacts the sheath. These stresses frequently lead to puncturing of the sheath, and resulting violation of the sterile field. The mounting arrangement according to the invention allows for gentler, controlled, non-torquing and non-shearing mounting of the guide onto the probe and thus greatly reduces the risk of puncturing the sheath”, where the claimed accessory interface apparatus includes the disclosed needle guide mounting arrangement 112, which is coupled to the ultrasound probe 100 across/over the sterile sheath),
wherein the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) includes a console disposed within the housing, the console having one or more processors and a non-transitory computer-readable storage medium having logic stored thereon that when executed by the one or more processors performs operations of the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) (see, e.g., Col. 3, lines 6-9, “As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown)”) that include:
exchanging data across the sterile [medical procedural] barrier between the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) and the ultrasound probe (100) (see, e.g., Col. 3, lines 5-10, “In FIG. 1, an ultrasound transducer probe 100 is shown in place against the body 102 of a patient. As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown) that generate transmission and driving signals for the piezoelectric array (also not shown) in the probe”, and Col. 5, lines 10-25, “This preferred mounting arrangement is particularly advantageous in the common case in which the needle guide and needle are in the sterile field of the surgical procedure, but the ultrasound probe itself is not. In these cases, the ultrasound probe is typically covered by a sterile sheath, which is typically made of Latex or of some other flexible synthetic material. The needle guide is then mounted over the sheath. Using know[n] needle guide mounts, there is a tendency to subject the sheath to rolling and shearing stresses where the guide contacts the sheath. These stresses frequently lead to puncturing of the sheath, and resulting violation of the sterile field. The mounting arrangement according to the invention allows for gentler, controlled, non-torquing and non-shearing mounting of the guide onto the probe and thus greatly reduces the risk of puncturing the sheath”).
Miller does not specifically disclose receiving input from the one or more optional accessories via an input/output (I/O) portal of the accessory interface apparatus.
However, in the same field of endeavor of ultrasound probes, Halmann discloses a medical ultrasound system (see, e.g., Figs. 1-2, Abstract, and Para. [0001-0006] and [0011-0014]), comprising: an ultrasound probe (ultrasound probe head 10) (see, e.g., Para. [0011]); and an accessory interface apparatus (needle tracking system 40, cables 60, console 70) including a housing (40) attached to the ultrasound probe (10), the accessory interface apparatus (40, 60, 70) configured to facilitate operational coupling between the ultrasound probe (10) and one or more optional accessories (needle 30) (see, e.g., Para. [0011-0013]),
wherein the accessory interface apparatus (40, 60, 70) includes a console (console 70) having one or more processors and a non-transitory computer-readable storage medium having logic stored thereon that when executed by the one or more processors performs operations of the accessory interface apparatus (40, 60, 70) (see, e.g., Para. [0011], “The console 70 has a processor for receiving and manipulating signals received from both the probe head 10 and the needle tracking system 40”) that include:
receiving input from the one or more optional accessories (30) via an input/output (I/O) portal of the accessory interface apparatus (40, 60, 70) (see, e.g., Para. [0011-0012], and Para. [0013], “In one embodiment needle tracking system 40 may rely upon signals obtained from the needle 30. The needle 30 or a portion thereof may be magnetized and needle tracking system 40 may rely on magnetic interactions with the needle 30. The needle 30 may be provided with a radio frequency identification (RFID) tag and the tag may be probed by the needle tracking system 40. The needle tracking system 40 may rely upon any of the known optical, mechanical, magnetic or electro-magnetic tracking technologies that provides a reasonable estimate of the location of a needle 30 inserted into living tissue 20”), and
exchanging data between the accessory interface apparatus (40, 60, 70) and the ultrasound probe (10) (see, e.g., Para. [0011-0014], where data is exchanged between the accessory interface apparatus (corresponding to 40, 60, 70) and the ultrasound probe (corresponding to 10) in order to provide a display image comprising the ultrasound image 82 obtained from the probe 10 and also comprising the graphical overlay 80 that indicates the predicted needle location data based on the signals received from the needle 30 obtained from the accessory interface apparatus (corresponding to 40, 60, 70)).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the medical ultrasound system and the accessory interface apparatus of Miller by including receiving input from the one or more optional accessories via an input/output (I/O) portal of the accessory interface apparatus, as disclosed by Halmann. One of ordinary skill in the art would have been motivated to make this modification in order to provides a reasonable estimate of the location of a needle inserted into living tissue, as recognized by Halmann (see, e.g., Para. [0013]).
Regarding claim 2, Miller modified by Halmann discloses the medical ultrasound system of claim 1, as set forth above. Miller further discloses the medical ultrasound system further comprising a display coupled with the ultrasound probe (see, e.g., Col. 3, lines 5-17, “In FIG. 1, an ultrasound transducer probe 100 is shown in place against the body 102 of a patient. As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown) that generate transmission and driving signals for the piezoelectric array (also not shown) in the probe. The array thereby generates an ultrasonic beam (illustrated in FIG. 1 as scan lines 106) that is focused into an interrogation region 108, that is, a region of interest in the patient's body. The acoustic echo signals from the region 108 return to the array and are converted back into electrical signals, which are processed in any known manner to generate a visual representation of the region on a display”).
Miller does not specifically disclose the operations further including depicting information on the display pertaining to the operation of the receiving the input from the one or more optional accessories in combination with an ultrasound image obtained by the ultrasound probe.
However, in the same field of endeavor of ultrasound probes, Halmann discloses the medical ultrasound system further comprising a display (display 72) coupled with the ultrasound probe (ultrasound probe head 10) (see, e.g., Para. [0011]), the operations further including depicting information on the display (72) pertaining to the operation of the receiving the input from the one or more optional accessories (needle 30) in combination with an ultrasound image obtained by the ultrasound probe (see, e.g., Para. [0011], “The console 70 has a processor for receiving and manipulating signals received from both the probe head 10 and the needle tracking system 40. The console 70 also has a display 72 on which the ultrasound image obtained from the probe head 10 may be viewed. The display may provide a graphical overlay 80 of the hollow needle 30 generated from information provided by the needle tracking system 40”, and Para. [0012-0013], and Para. [0014], “Referring to FIG. 2, the display 72 provides an ultrasound image 82 of the tissue 20 on which a predicted location 80 of needle 30 has been identified. The predicted location 80 of needle 30 is generated from data supplied by the needle tracking system 40. It provides approximate information as to the location of the needle 30 in the tissue 20. However, the graphical overlay 80 is not obtained from the ultrasound data used to image the tissue 20. Thus it does not represent an ultrasound image of the needle 30”, where data is exchanged between the accessory interface apparatus (corresponding to 40, 60, 70) and the ultrasound probe (corresponding to 10) in order to provide a display image comprising the ultrasound image 82 obtained from the probe 10 and also comprising the graphical overlay 80 that indicates the predicted needle location data based on the signals received from the needle 30 obtained from the accessory interface apparatus (corresponding to 40, 60, 70)).

One of ordinary skill in the art would have been motivated to make this modification in order to provides a reasonable estimate of the location of a needle inserted into living tissue, as recognized by Halmann (see, e.g., Para. [0013]).
Regarding claim 5, Miller modified by Halmann discloses the medical ultrasound system of claim 1, as set forth above.

In these cases, the ultrasound probe is typically covered by a sterile sheath, which is typically made of Latex or of some other flexible synthetic material. The needle guide is then mounted over the sheath. Using know[n] needle guide mounts, there is a tendency to subject the sheath to rolling and shearing stresses where the guide contacts the sheath. These stresses frequently lead to puncturing of the sheath, and resulting violation of the sterile field. The mounting arrangement according to the invention allows for gentler, controlled, non-torquing and non-shearing mounting of the guide onto the probe and thus greatly reduces the risk of puncturing the sheath”, where the claimed accessory interface apparatus includes the disclosed needle guide mounting arrangement, which is coupled to the ultrasound probe across/over the sterile sheath).
Regarding claim 7, Miller modified by Halmann discloses the medical ultrasound system of claim 1, as set forth above. Miller further discloses the medical ultrasound system further comprising the medical procedural barrier, the medical procedural barrier including a sheath covering the ultrasound probe (see, e.g., Col. 5, lines 10-25, “This preferred mounting arrangement is particularly advantageous in the common case in which the needle guide and needle are in the sterile field of the surgical procedure, but the ultrasound probe itself is not. In these cases, the ultrasound probe is typically covered by a sterile sheath, which is typically made of Latex or of some other flexible synthetic material.

These stresses frequently lead to puncturing of the sheath, and resulting violation of the sterile field. The mounting arrangement according to the invention allows for gentler, controlled, non-torquing and non-shearing mounting of the guide onto the probe and thus greatly reduces the risk of puncturing the sheath”).
Regarding claim 9, Miller modified by Halmann discloses the medical ultrasound system of claim 1, as set forth above. Miller does not specifically disclose wherein the I/O portal includes one or more of an electrical connection, an optical coupling, an inductive coupling or a wireless connection between the accessory interface apparatus and the one or more optional accessories.

[0011], “Referring to FIG. 1, an ultrasound probe head 10 is placed adjacent to living tissue 20, such as human tissue. A needle tracking system 40 is attached to the probe head 10 and measures the depth and angle of insertion of a hollow needle 30. […] The probe head 10 is connected to cables 60 which are, in turn, connected to an ultrasound console 70. The console 70 has a processor for receiving and manipulating signals received from both the probe head 10 and the needle tracking system 40”, and Para. [0012], “In one embodiment, the needle tracking system 40 supplies data to the console 70 from which an estimate of the position of the needle 30 is formulated and may be graphically represented a feature 80. In one embodiment, the data from the needle tracking system 40 includes the angle of insertion, the depth of insertion, and the angle of insertion of needle 30 into tissue 20. This data is used to provide a predicted position 80 of needle 30”, and Para. [0013], “In one embodiment needle tracking system 40 may rely upon signals obtained from the needle 30.

Regarding claim 4, Miller modified by Halmann discloses the medical ultrasound system of claim 1. Halmann further discloses wherein the accessory interface apparatus (needle tracking system 40, cables 60, console 70) exchanges data to/from the ultrasound probe (ultrasound probe head 10) (see, e.g., Para. [0011], “Referring to FIG. 1, an ultrasound probe head 10 is placed adjacent to living tissue 20, such as human tissue. A needle tracking system 40 is attached to the probe head 10 and measures the depth and angle of insertion of a hollow needle 30. […] The probe head 10 is connected to cables 60 which are, in turn, connected to an ultrasound console 70. The console 70 has a processor for receiving and manipulating signals received from both the probe head 10 and the needle tracking system 40. The console 70 also has a display 72 on which the ultrasound image obtained from the probe head 10 may be viewed. The display may provide a graphical overlay 80 of the hollow needle 30 generated from information provided by the needle tracking system 40”, and Para. [0012], “In one embodiment, the needle tracking system 40 supplies data to the console 70 from which an estimate of the position of the needle 30 is formulated and may be graphically represented a feature 80. In one embodiment, the data from the needle tracking system 40 includes the angle of insertion, the depth of insertion, and the angle of insertion of needle 30 into tissue 20. This data is used to provide a predicted position 80 of needle 30”, and Para. [0013], “In one embodiment needle tracking system 40 may rely upon signals obtained from the needle 30. The needle 30 or a portion thereof may be magnetized and needle tracking system 40 may rely on magnetic interactions with the needle 30.

The needle tracking system 40 may rely upon any of the known optical, mechanical, magnetic or electro-magnetic tracking technologies that provides a reasonable estimate of the location of a needle 30 inserted into living tissue 20”, and Para. [0014], “Referring to FIG. 2, the display 72 provides an ultrasound image 82 of the tissue 20 on which a predicted location 80 of needle 30 has been identified. The predicted location 80 of needle 30 is generated from data supplied by the needle tracking system 40. It provides approximate information as to the location of the needle 30 in the tissue 20. However, the graphical overlay 80 is not obtained from the ultrasound data used to image the tissue 20. Thus it does not represent an ultrasound image of the needle 30”, where data is exchanged between the accessory interface apparatus (corresponding to 40, 60, 70) and the ultrasound probe (corresponding to 10) in order to provide a display image comprising the ultrasound image 82 obtained from the probe 10 and also comprising the graphical overlay 80 that indicates the predicted needle location data based on the signals received from the needle 30 obtained from the accessory interface apparatus (corresponding to 40, 60, 70)).
Miller modified by Halmann does not specifically disclose wherein the accessory interface apparatus receives electrical power from the ultrasound probe via at least one of electrical contacts or a magnetic field configured to inductively transfer the electrical power to the accessory interface apparatus.
However, in the same field of endeavor of ultrasound probes, Poland discloses wherein the accessory interface apparatus receives electrical power from the ultrasound probe via at least one of electrical contacts or a magnetic field configured to inductively transfer the electrical power to the accessory interface apparatus (see, e.g., Para. [0048], “FIG. 10a illustrates a cable suitable for use with a wireless probe of the present invention. While various types of multi-conductor cables and connectors can be used for a wireless probe, this example is a multi-conductor USB cable 300 with a USB type A connector 310 at one end. Extending from the connector 310 is a type A USB adapter 312. Other USB formats may alternatively be employed, such as type B and mini-B as is found on digital cameras, or a completely custom connector with other desirable properties may be employed. A USB cable can be plugged into virtually any desktop or laptop computer, enabling the wireless probe to be charged from virtually any computer. When the host system is a laptop-style ultrasound system 50 as shown in FIGS. 2b and 6a, the USB-type cable can be used for both signal communication to and from the host as well as power”, where the cable can be used to transmit power and signal communication to and from the probe and the interface apparatus/connector, thus the interface apparatus can receive electrical power from the probe via electrical contacts associated with the cable).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have further modified the medical ultrasound system of Miller modified by Halmann by including wherein the accessory interface apparatus receives electrical power from the ultrasound probe via at least one of electrical contacts or a magnetic field configured to inductively transfer the electrical power to the accessory interface apparatus, as disclosed by Poland. One of ordinary skill in the art would have been motivated to make this modification in order to improve communication performance, such as a greater bandwidth for transmission of diagnostics or upgrades of the probe's firmware or software, as recognized by Poland (see, e.g., Para. [0047-0048]).
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Miller (US Patent No. 5,758,650 A) in view of Halmann (US 2015/0209003 A1), as applied to claim 1 above, and further in view of Halmann et al. (US 2016/0000399 A1, with publication date 01/07/2016, hereinafter Halmann ‘399).
Regarding claim 8, Miller modified by Halmann discloses the medical ultrasound system of claim 1. Halmann further discloses wherein the exchanging the data takes place (see, e.g., Para. [0013], “In one embodiment needle tracking system 40 may rely upon signals obtained from the needle 30.

The needle 30 may be provided with a radio frequency identification (RFID) tag and the tag may be probed by the needle tracking system 40. The needle tracking system 40 may rely upon any of the known optical, mechanical, magnetic or electro-magnetic tracking technologies that provides a reasonable estimate of the location of a needle 30 inserted into living tissue 20”).
Miller modified by Halmann does not specifically disclose wherein the exchanging the data [between the accessory interface apparatus and the ultrasound probe] takes place across at least one of a wireless connection or an optical connection.
However, in the same field of endeavor of ultrasound needle guidance, Halmann ‘399 discloses wherein the exchanging the data [between the accessory interface apparatus (needle 90, needle tracking system 93) and the ultrasound probe (probe 106, ultrasound imaging system 91)] takes place across at least one of a wireless connection or an optical connection (see, e.g., Para. [0030], “According to the embodiment shown in FIG. 1, the needle tracking system 93 is a magnetic tracking system and it includes an emitter 122 disposed in the probe 106 and a sensor 124 disposed in the needle 90. According to an exemplary embodiment, the emitter 122 may comprise a magnetic sensor board. The magnetic sensor board includes a magnetic field generator configured to emit an electromagnetic field of a known direction and intensity. The sensor 124 disposed in the needle 90 may include three sets of coils […] By detecting the currents induced in each of the coils, position and orientation information may be determined from the sensor 124. According to an embodiment, the processor 116 is in electronic communication with the needle tracking system 93. For example, the probe 106 may be connected to the processor 116 via either a wired or a wireless connection. Likewise, position data from the sensor 124 may be communicated to the processor 116 via either a wired connection or through wireless techniques”, and Fig. 1, where the sensor 124 of the needle 90, needle tracking system 93 communicates to the processor 116 via the sensor’s connection to the probe 106, in which each of the connections may be through wireless techniques).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have further modified the medical ultrasound system of Miller modified by Halmann by including wherein the exchanging the data takes place across at least one of a wireless connection or an optical connection, as disclosed by Halmann ‘399. One of ordinary skill in the art would have been motivated to make this modification in order to desirably determine position and orientation information from the sensor by detecting the currents induced in each of the coils on the sensor, as recognized by Halmann ‘399 (see, e.g., Para. [0025] and [0030]), and further using a wireless connection to transmit data is a known effective alternative to using a wired connection, as recognized by Halmann ’399 (see, e.g., Para. [0030]).

A needle tracking system 40 is attached to the probe head 10 and measures the depth and angle of insertion of a hollow needle 30. […] The probe head 10 is connected to cables 60 which are, in turn, connected to an ultrasound console 70. The console 70 has a processor for receiving and manipulating signals received from both the probe head 10 and the needle tracking system 40”, and Para. [0012], “In one embodiment, the needle tracking system 40 supplies data to the console 70 from which an estimate of the position of the needle 30 is formulated and may be graphically represented a feature 80. In one embodiment, the data from the needle tracking system 40 includes the angle of insertion, the depth of insertion, and the angle of insertion of needle 30 into tissue 20. This data is used to provide a predicted position 80 of needle 30”, and Para. [0013], “In one embodiment needle tracking system 40 may rely upon signals obtained from the needle 30. The needle 30 or a portion thereof may be magnetized and needle tracking system 40 may rely on magnetic interactions with the needle 30.

The needle tracking system 40 may rely upon any of the known optical, mechanical, magnetic or electro-magnetic tracking technologies that provides a reasonable estimate of the location of a needle 30 inserted into living tissue 20”).
Miller modified by Halmann does not specifically disclose wherein the accessory interface apparatus provides power to the one or more optional accessories.
However, in the same field of endeavor of ultrasound needle guidance, Keenan discloses wherein the accessory interface apparatus (assembly 5, power source 15, RF control 54) provides power to the one or more optional accessories (needle 6, radiofrequency probes 53) (see, e.g., Page 23, lines 18-28 and Page 24, lines 1-2, “Figure 9A depicts the invention being used to position a needle under real-time ultrasound guidance. An ultrasound transducer (1) transmits and receives pulses in order to image the interior of a patient (2) on an ultrasound display (3). The handheld assembly (5) is used to insert a needle (6) into the patient towards the desired point of action (4), such as a solid tumor. Fluid 1, the echogenic fluid, (19), is ejected from the distal tip of the needle (7) at sufficient speed and for sufficient travel distance as to be detectable by the ultrasound. Radiofrequency probes (53) inside the needle (6) are connected through a sealed needle adaptor (26) to the RF control (54) and power source (15)”, where the power source 15 provides power to the radiofrequency probes 53 inside the needle 6 via the connection through the sealed needle adaptor 26).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have further modified the medical ultrasound system of Miller modified by Halmann by including wherein the accessory interface apparatus provides power to the one or more optional accessories, as disclosed by Keenan.

Response to Arguments
Applicant's arguments, see Remarks filed 12/02/2025, have been fully considered but they are not persuasive.
Regarding Miller (US Patent No. 5,758,650 A) and Halmann (US 2015/0209003 A1), Applicant argues that Miller and Halmann fail to teach, individually or in any combination of the two, “an accessory interface apparatus including a housing attached with the ultrasound probe” where “the accessory interface apparatus includes a console disposed within the housing”.
Examiner respectfully disagrees and emphasizes that Miller modified by Halmann does teach each and every limitation of independent claims 1 and 18, as set forth above.
Examiner emphasizes that Miller discloses an accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) including a housing (Fig. 1: main guide body 114 of needle guide 112 and comprising mounting arrangement 118) attached to the ultrasound probe (100), the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) configured to facilitate operational coupling between the ultrasound probe (100) and one or more optional accessories (Fig. 1: needle 110) (see, e.g., Fig. 1, and Col. 3, lines 5-13, “In FIG. 1, an ultrasound transducer probe 100 is shown in place against the body 102 of a patient. As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown) that generate transmission and driving signals for the piezoelectric array (also not shown) in the probe. The array thereby generates an ultrasonic beam (illustrated in FIG. 1 as scan lines 106) that is focused into an interrogation region 108, that is, a region of interest in the patient's body”, and Col. 3, lines 35-40, “The needle 110 is guided and secured by a needle guide, which is indicated generally as the guide 112. The main features of the guide 112 are a main guide body 114, a removable, exchangeable needle cap 116 that fits and is held onto the main body, and a mounting arrangement 118, which is attached to or is an integral portion of the main body 114” (emphasis added), and Col. 3, lines 53-57, “The mounting arrangement 118 preferably includes, for example, arms with protrusions (FIG. 2) that fit into respective indentations, recesses or grooves on either side of the probe 100, as well as in a side surface 130 of the probe, to fix the position of the needle guide relative to the probe” (emphasis added)), wherein the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) includes a console disposed within the housing, the console having one or more processors and a non-transitory computer-readable storage medium having logic stored thereon that when executed by the one or more processors performs operations of the accessory interface apparatus (Fig. 1: needle guide 112, cable 104, console/processing circuits) (see, e.g., Col. 3, lines 6-9, “As in known systems, the probe is connected by a cable to various conventional driving, processing and display circuits (not shown)”).
Therefore, the combination of Miller modified by Halmann does teach each and every limitation of independent claims 1 and 18, as set forth above.
