Claim 15-16 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kunio et al. (WO 2021/055837; hereinafter Kunio). Regarding claim 15, Kunio discloses a catheter with AI co-registration and marker detection. Kunio shows a system (see fig. 1A-B), comprising: a processor circuit (see 26, 40, 50 in fig. 1B) configured for communication with an extraluminal imaging device (see par. [0014], [0087], fig. 1B), wherein the processor circuit is configured to: receive a plurality of extraluminal images obtained by the extraluminal imaging device during movement of an intraluminal catheter along a guidewire within a body lumen of a patient (see par. [0014], [0081], [0082]), wherein the plurality of extraluminal images are obtained without a contrast agent within the body lumen (see par. [0020], [0096] and fig. 2 does not state that a contrast agent is used or injected into the patient for the angiography), wherein the plurality of extraluminal images show the guidewire and a radiopaque portion of the intraluminal catheter (see par. [0017], [0019], [0029], [0032], [0130], [0198]); determine a path of the movement based on corresponding locations of the radiopaque portion in the plurality of extraluminal images, wherein the path comprises a first shape (see par. [0014], [0017], [0081]-[0083], [0087], [0088], [0118]); output, to a display in communication with the processor circuit, a pathway review screen display associated with use of the intraluminal catheter during an intraluminal procedure of the patient (see par. [0014], [0017], [0019], [0029], [0032], [0087], [0130], [0198]), wherein the pathway review screen display comprises: an extraluminal image of the plurality of extraluminal images (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]); and the path is the extraluminal image of the first shape (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]); receive a user input to modify the pathway review screen display (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]), wherein the user input comprises changing the path (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]), in the pathway review screen display (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]), to have a second shape matching a shape of the guidewire in the extraluminal image (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]) such that, after the user input, the pathway review screen display comprises: the extraluminal image (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]); and the path in the extraluminal image with the second shape (see par. [0014], [0017], [0019], [0029], [0032], [0130], [0198]). Regarding claim 16, Kunio shows further comprising the intraluminal catheter (see fig. 1B), wherein the intraluminal catheter comprises an intravascular imaging catheter configured for (see par.

[0025]); wherein the plurality of extraluminal images comprises a plurality of x-ray images (see par. [0020], [0025])), wherein the body lumen comprises a blood vessel of the patient (see par. [0020], [0025]); wherein the processor circuit is configured to: receive a plurality of intravascular images obtained by the intravascular imaging catheter during the movement of the intravascular imaging catheter (see par. [0015]); co-register the plurality intravascular images to positions along the path with the second shape (see par. [0087]-[0088], [0091]; and output, to the display, a intraluminal imaging review screen display comprising: a second x-ray image of the plurality of x-ray images (see par. [0017], [0019], [0029], [0032], [0088], [0130], [0198]); a intravascular image (see par. [0017], [0019], [0029], [0032], [0088], [0130], [0198]); and a marking in second x-ray image representative a corresponding position of the intravascular image along the path with the second shape (see par. [0017], [0019], [0029], [0032], [0088], [0130], [0198]). Response to Arguments The previous prior art rejection to claim 1 and all dependent claims thereof has been withdrawn in view of Applicant’s amendment to claim 1. Applicant's arguments filed 12/30/2025 have been fully considered but they are not persuasive. In response to Applicant’s argument with respect to prior art rejection of claim 15, the examiner respectfully disagrees. The examiner maintains that prior art Kunio does show receiving a user input to modify the pathway review screen display, wherein the user input comprises changing the path, in the pathway review screen display, to have a second shape, matching of a shape of the guide-wire in the extraluminal image (see par. [0014], [0017], [0029], [0032], [0130], [0198]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Cathier et al. (2016/0270758) disclose integration ultrasound and X-ray modalities and Masaki et al. (US 2021/0369355) disclose robotic endoscope probe having orientation reference markers.
