Office Action

§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-6, 9-24 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Devgon et al (US 2020/0230358 A1). Regarding claim 1, Devgon discloses a medical device comprising: an instrument 260 having a proximal end and a distal end; an instrument delivery device 210 (introducer) configured to moveably receive the instrument 260 and having: an outer housing 220 having a proximal end, a distal end, and a sidewall therebetween defining an inner volume; and an inner housing 265 having a proximal end, and a grip 269 arranged at the proximal end, a distal end, and a sidewall therebetween defining an inner volume, the inner housing 265 coupled to the instrument 260 and slidably received within the outer housing in a telescoping relationship (figs 22-24); the distal end of the instrument delivery device 210 configured to couple the instrument delivery device to an intravenous line via lock 240 [0008]; and wherein the inner housing 265 is configured to move relative to the outer housing to move the instrument between a first position (fig 3), in which the inner housing 265 extends proximally from the outer housing 210 and in which the instrument 260 is disposed within the outer housing, and a second position, in which a portion of the inner housing 265 is received within outer housing (fig 4) and in which the distal end of the instrument 260 is disposed beyond the distal end of the outer housing (fig 25) such that at least a first portion of the instrument 260 is disposed within the intravenous line when the instrument delivery device is coupled to the intravenous line. Regarding claim 2, Devgon discloses the outer housing 220 comprises a lock 240 at the distal end thereof, the lock configured to couple the instrument delivery device 210 to an intravenous line (fig 5; abstract; [0008]). Regarding claim 3, Devgon discloses a joint 216 ([0089], can be seen in fig 4) is arranged at the distal end of the outer housing. Regarding claim 4, the joint is a rotating joint (threads, [0089]). Regarding claim 5, Devgon further comprising a septum (seal, [0089-0090]) arranged at the distal end of the outer housing. Regarding claim 6, further comprising a seal (seal, [0089]) arranged at the proximal end of the instrument. Regarding claims 9-10, Devgon discloses the instrument is a catheter. Regarding claims 11-13, the inner housing at 265 includes a clamp at the proximal end thereof, configured to selectively block fluid flow through the inner housing (see fig 24, [0105, 0128]). Regarding claim 14, Devgon discloses the inner housing is in fluid communication with the catheter 260, such that fluid flowing proximally from the catheter is received within the inner housing (fig 24). Regarding claim 15, Devgon discloses the inner housing 265 further comprises a fluid conduit 268 (figs 25-28) in fluid communication with the catheter 260. Regarding claim 16, Devgon discloses the fluid conduit 265 (figs 27-28) extends proximally beyond the proximal end of the inner housing. Regarding claim 17, further comprising a fluid conduit ([0106]; the coupler 269 can be connected to fluid conduits such as a fluid reservoir, fluid source, syringe, evacuated container holder pump, and/or the like coupled to the proximal end of the inner housing 265 (at coupler 269). Regarding claim 18, Devgon further comprising one or support 986 (figs 42-43; [0161-0164]) arranged within the outer housing 910 and configured to limit buckling of the instrument 960 as it is advanced through the outer housing 910. Regarding claim 19, Devgon discloses in an alternative embodiment the inner housing 1086 is formed of a material with sufficient stiffness to limit and/or prevent buckling of the inner housing as it is advanced through the outer housing [0167]. Therefore, inner housing 265 can be made of the same material. Regarding claim 20, Devgon discloses an inner diameter of the outer housing (figs 5-7, and 44) is configured such that buckling of the inner housing and/or instrument is limited and/or prevented when the inner housing is advanced through the outer housing. Regarding claim 21, Devgon further comprising a seal (friction fit at 276 [0202]) arranged about an outer circumference of the instrument, and slidable with the instrument through the outer housing. Regarding claim 22, further comprising one or more indicia arranged on instrument delivery device (210, fig 3, [0119, 0131]). Regarding claim 23, Devgon discloses the one or more indicia are visual and/or tactile indicia [0119, 0131]. Regarding claim 24, Devgon discloses the inner housing comprises a connector 269 at the proximal end thereof. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Devgon et al (US 2020/0230358 A1) in view of Burkholz et al (US 20190321590 A1). Devgon (‘358) discloses the invention substantially as claimed. However, it fails to disclose the medical device further comprising lubricant [liquid, 0090] arranged at one or more locations within the outer housing. Burkholz teaches, ([0067]; figure 1B), that a silicon lubricant can be disposed between catheter 12 (inside outer housing 20) and septum 51. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Devgon’s (‘358) medical device by including a lubricant arranged at one or more locations within the outer housing taught by Burkholz since it would prevent friction between outer and inner housings and instrument during procedure and ease delivery of the instrument. Claim 25 is rejected under 35 U.S.C. 103 as being unpatentable over Devgon et al (US 2020/0230358 A1) in view of Devgon et al (US 10,076,272 B2). Devgon (‘358) discloses the invention substantially as claimed. Devgon discloses the apparatus/medical device 200 to be used with a peripheral intravenous catheter (PIV) system 105 (fig 2; not shown for figs 3-29). However, Devgon (‘358) does not teach the specifics of the system set forth in claim 25. Devgon (‘272) teaches (in figures 9-14), a system 6000, comprising: a catheter assembly 6400 comprising: a catheter adapter 6300, comprising a distal end; a proximal end; a lumen 6401 (fig 14) extending between the distal end and the proximal end; and a side port 6420 arranged between the distal end and the proximal end, the side port in fluid communication with the lumen 6401; a catheter secured to the distal end of the catheter adapter 6300 and extending distally from the catheter adapter 6300; and a fluid conduit 6425 having a proximal end coupled to the side port and a distal end, the fluid conduit in fluid communication with the side port; and a medical device (introducer 6100). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Devgon (‘358) system (medical device/introducer and PIV system) with the catheter assembly (PIV system) of Devgon (‘272) since such modification is a mere substitution of functionally equivalents parts. Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See PTO-892 form.
