Office Action

§102 §112
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 . Election/Restrictions Claim 19 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Group 2, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on February 10, 2026. 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 11-18 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 11, lines 7-10 recites the phrase “wherein the elongate shaft includes a reverse curve portion curved in a second direction opposite the first direction; wherein the elongate shaft includes a reverse curve portion curved in a second direction opposite the first direction.” It is suggested to delete the duplicate phrase. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-8 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Daniels (US 2017/0266434).

Regarding claim 5, Daniels additionally discloses wherein the proximal section of the elongate shaft includes a bare metal portion that is adapted to accommodate an alligator clip connecting the elongate shaft with the pacing system (e.g. proximal end of lead is connected to external pulse generator 142 as disclosed in [0036]). Regarding claim 6, Daniels additionally discloses wherein the proximal section of the elongate shaft includes a bare metal proximal end that is adapted to accommodate an electrical connection with the pacing system (e.g. proximal end of lead is connected to external pulse generator 142 as disclosed in [0036] and will thus necessarily have a mental connecting portion). Regarding claim 7, Daniels additionally discloses wherein the elongate shaft includes a polymeric coating over an entirety of the elongate shaft with the exception of: the one or more electrodes; and a bare metal region of the proximal section (e.g. PTFE coating as describe din [0040]). Regarding claim 8, Daniels additionally discloses wherein at least a proximal-most region of the proximal section includes an uninsulated metal core and an insulated coil extending over the uninsulated metal core (e.g. uninsulated core wire 552 and insulated coils 1754 as shown in Figure 17 and disclosed in [0067]). Claims 1-18 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Wang (US 2024/0058585). Regarding claim 1, Wang discloses the claimed guidewire for delivering a replacement heart valve implant comprising: an elongate shaft including a distal section and a proximal section extending proximally from the distal section (e.g. guidewire 100 as shown in Figure 1, 2, and 12 including proximal end 1204); a coiled portion disposed within the distal section (e.g. pigtail portion 102a), and one or more electrodes disposed within the coiled portion, the one or more electrodes adapted for pacing the heart (e.g. electrodes 150); wherein the proximal section is adapted to provide an electrical connection with a pacing system (e.g. proximal end 1204 for connecting with a pacing system Regarding claim 2, Wang additionally discloses wherein the elongate shaft includes a polymeric coating disposed on the coiled portion (e.g. PTFE insulation as disclosed in [0057]). Regarding claim 3, Wang additionally discloses wherein the one or more electrodes disposed within the coiled portion comprise spots in the coiled portion in which the polymeric coating has been removed to expose metal underneath the polymeric coating (e.g. holes in insulation 603 that expose electrodes 650 as shown in Figure 6). Regarding claim 4, Wang additionally discloses wherein at least some of the one or more electrodes are adapted to contact a ventricular wall of a heart when the coiled portion is disposed within a ventricle of the heart (e.g. device is capable of being implanted in the position as shown in Figure 2). Regarding claim 5, Wang additionally discloses wherein the proximal section of the elongate shaft includes a bare metal portion that is adapted to accommodate an alligator clip connecting the elongate shaft with the pacing system (e.g. device is capable of being attached via alligator clip to the distal end of the guidewire as disclosed in [0069]). Regarding claim 6, Wang additionally discloses wherein the proximal section of the elongate shaft includes a bare metal proximal end that is adapted to accommodate an electrical connection with the pacing system (e.g. proximal end 1320 as shown in Figure 12B that is bare metal and capable of electrical connection with the pacing electrode as disclosed in [0063]). Regarding claim 7, Wang additionally discloses wherein the elongate shaft includes a polymeric coating over an entirety of the elongate shaft with the exception of: the one or more electrodes; and a bare metal region of the proximal section (e.g. PTFE insulation as disclosed in [0057] and as shown in Figures 1, 9, and 12).
