Office Action

§102
DETAILED ACTION Status of Claims The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-4, 6-24, 26, and 28 are pending. Claims 5, 25, 27 are cancelled. Claim Rejections - 35 USC § 102 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 1-4, 6-24, 26, and 28 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bukesov et al. (US 20210038304 A1, 2021-02-11) (hereinafter “Bukesov”). Regarding claim 1, Bukesov teaches medical system (and a method of use), comprising: an elongate medical device, comprising one or more optical fibers extending between a proximal end and a distal end (e.g.., [0101]-[0103]; Figs. 4A, 4B) the elongate medical device configured for advancement along a urinary tract of a patient (e.g., [0079], [0101]); a console coupled with the elongate medical device at the proximal end, the console including one or more processors and a non-transitory computer-readable medium having stored thereon logic that, when executed by the one or more processors ([0086], [0092], [0097], [0147], [0153][, 0156]; Figs. 2, 12), causes operations including: projecting a coherent light away from the distal end onto a kidney stone within the patient ([0066]; Figs. 1, 2); receiving a reaction light signal emanating from the kidney stone in response to the coherent light ([0066]; Figs. 1, 2); and processing the reaction light signal to determine therefrom a material composition of the kidney stone, wherein the one or more of the optical fibers includes a fiber optic laser ([0066], [0087], [0088]; Fig. 2, 3A, 3B) (as recited in claims 1 and 16); wherein the elongate medical device is configured for advancement along a working channel of a ureteroscope (e.g., [0102]) (as recited in claims 2 and 26); wherein the projected coherent light is configured to cause fragmentation of the kidney stone (e.g., [0060], [0101]) (as recited in claim 3); wherein the coherent light is projected from a plurality of optical fibers (e.g., [0126]) (as recited in claim 4); wherein the coherent light includes a plurality of wavelengths (e.g., [0069]-[0073], [0103]) (as recited in claims 6 and 17); wherein the reaction light signal includes a plurality of wavelengths (e.g., [0087]-[0088]) (as recited in claims 7 and 18); wherein the reaction light signal is defined at least partially by reflections of the coherent light (e.g., [0066], [0087]-[0088]) (as recited in claims 8 and 19); wherein:processing the reaction light signal includes defining a spectroscopy signature for the kidney stone based on the reaction light signal, and the spectroscopy signature includes a plurality of wavelengths, each wavelength having a corresponding intensity (e.g., [0081]-[0083], [0086-[0088]) (as recited in claims 9 and 20); wherein processing the reaction light signal includes: comparing the spectroscopy signature with one or more spectroscopy signatures stored in memory, the spectroscopy signatures stored in memory representing different material compositions of kidney stones, and as a result of the comparison, determining the material composition of the kidney stone (e.g., [0081]-[0083], [0086-[0088]) (as recited in claims 10 and 21); wherein the operations further include: receiving input information, the input information including an independent composition assessment of the kidney stone after removal from the patient; relating the input information to the spectroscopy signature; and combining the spectroscopy signature with at least at least one spectroscopy signature stored in memory to enhance an accuracy of the at least one spectroscopy signature stored in memory (e.g., [0081]-[0083], [0086-[0088]) (as recited in claims 11 and 22); wherein the reaction light signal is received through one or more of the optical fibers (e.g., [0078], [0125]) (as recited in claims 9 and 28); wherein: the coherent light projected from a first subset of optical fibers is configured to cause fragmentation of the kidney stone, and the coherent light projected from a second subset of optical fibers is configured to induce the reaction light signal (e.g., [0066], [0087], [0088], [0094], [0126]) (as recited in claim 9); wherein projecting the coherent light to cause fragmentation of the kidney stone is performed in accordance with operational settings, the operational settings including one or more of a pulse frequency, a pulse duration, or a wavelength of the coherent light (e.g., [0066], [0087], [0088], [0094], [0126]) (as recited in claims 14 and 23); wherein at least one of the operational settings is defined at least partially based on the determined material composition of the kidney stone (e.g., [0066], [0087], [0088], [0094], [0126]) (as recited in claims 15 and 24).
