Claim Rejections - 35 USC § 103
The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action:
(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim 3 is rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Podmore in view of Boulais et al. (previously presented-US 20060106281 A1), hereinafter “Boulais”.
Regarding claim 3, Podmore discloses all of the limitations of claim 1, as described above.
Podmore does not explicitly disclose wherein the visualization sensor further comprises an integrated light source.
Boulais teaches a tissue modification device comprising a visualization sensor ([0113]; Figure 8—element 810) and a tissue modifier configured to deliver ultrasound energy to tissue ([0044] & [0114]; Figure 8—element 822), wherein the visualization sensor further comprises an integrated light source ([0113]; Figure 8—element 812).
A person of ordinary skill in the art, before the effective filing date of the claimed invention would have been motivated to modify the visualization sensor, as disclosed by Podmore, to include an integrated light source, as taught by Boulais, as both references and the claimed invention are directed toward tissue modification devices comprising integrated visualization sensors. As disclosed by Boulais, the visualization sensor comprises a light source which may be a light emitting diode or a fiber optic in order to illuminate the tissue to be examined ([0003] & [0113]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the visualization sensor, as disclosed by Podmore, to include an integrated light source, as taught by Boulais, as such a modification would illuminate the tissue to be examined by the visualization sensor.
Claims 6-7 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Podmore in view of Hossack et al. (previously presented-US 6045508 A), hereinafter “Hossack”.
Regarding claims 6 & 7, Podmore discloses all of the limitations of claim 1, as described above.
Podmore does not disclose a sensor positioned at the distal end of the rigid elongated member (claim 6); wherein the sensor comprises an accelerometer (claim 7).
Hossack teaches an ultrasonic device for imaging ([Col. 3, lines 28-60]; Figure 1—element 10), comprising a rigid elongated member ([Col. 3, lines 28-51]; Figure 1—element 12), a sensor positioned at the distal end of the rigid elongated member (claim 6); wherein the sensor comprises an accelerometer (claim 7) ([Col. 9, lines 55-63]).
A person of ordinary skill in the art, before the effective filing date of the claimed invention, would have been motivated to modify the distal end, as disclosed by Podmore, to include a sensor positioned at the distal end of the rigid elongated member, wherein the sensor comprises an accelerometer, as taught by Hossack, as both references and the claimed invention are directed toward tissue modifiers comprising ultrasonic probes. As disclosed by Hossack, the ultrasonic probe can include an absolute sensor incorporated in its distal end for position or orientation feedback, such as an accelerometer ([Col. 9, lines 55-63]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the distal end, as disclosed by Podmore, to include a sensor positioned at the distal end of the rigid elongated member, wherein the sensor comprises an accelerometer, as taught by Hossack, as such a modification would provide for a sensor that provides feedback regarding the position and orientation of the ultrasonic probe within tissue.
Claims 6 & 8 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Podmore in view of Law et al. (previously presented-US 5469853 A), hereinafter “Law”.
Regarding claims 6 & 8, Podmore discloses all of the limitations of claim 1, as described above.
Podmore does not disclose a sensor positioned at the distal end of the rigid elongated member (claim 6); wherein the sensor comprises an optical encoder (claim 8).
Law teaches a tissue modification device comprising a rigid elongated member comprising a distal end ([Col. 28, line 66 – Col. 29, line 10] & [Col. 29, lines 34-51]; Figure 38—element 402 & 404), and comprising a sensor positioned at the distal end of the rigid elongated member (claim 6); wherein the sensor comprises an optical encoder (claim 8) ([Col. 31, line 49 – Col. 32, line 6]; Figure 45—element 470).
A person of ordinary skill in the art, before the effective filing date of the claimed invention, would have been motivated to modify the distal end, as disclosed by Podmore, to include a sensor positioned at the distal end of the rigid elongated member, wherein the sensor comprises an optical encoder, as taught by Law, as both references and the claimed invention are directed toward tissue modifiers comprising ultrasonic probes with bendable distal ends. As disclosed by Law, the distal end of the ultrasonic probe can include an angle sensor, such as an optical encoder, to sense the angle of the bend of the distal end of the ultrasonic probe and provide feedback to assist the surgeon in performing the procedure ([Col. 31, line 49 – Col. 32, line 6]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the distal end, as disclosed by Podmore, to include a sensor positioned at the distal end of the rigid elongated member, wherein the sensor comprises an optical encoder, as taught by Law, as such a modification would provide for a sensor that provides feedback to a surgeon regarding the angle of the bend of the distal end of the device to further assist the surgeon in performing the surgical procedure.
