Iversen discloses wherein one terminal end of each of the string-shaped members is not fixed to the holding parts ([0105], “mitral valve … is anchored to the wall of the left ventricle … by chordae tendineae” Examiner notes that chordae tendineae are string-shaped members.). Okayama and Iversen combined are considered analogous to the claimed invention because they are in the field of catheter simulators, heart models, and valve repair devices and processes. Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the applicant’s invention for a catheter simulator for practicing catheter manipulations in a state of holding a heart model in a container filled with a liquid, the heart model including a main body formed from an elastic material and including a left atrium and a left ventricle, with a mitral valve installed at a boundary portion between the left atrium and the left ventricle, wherein the container includes a holding part for holding the heart model, and an introduction part capable of inserting a catheter, a pump for circulating the liquid to be filled in the container into the heart model is connected to the container, the pump is intermittently driven so that a pulsatile flow flows from the left atrium toward the left ventricle in the heart model held in the container, and a catheter surgery, and a catheter can be practiced against the anterior leaflet and the posterior leaflet of the heart model held by the holding part, as disclosed by Okayama, the mitral valve including an anterior leaflet and a posterior leaflet, both the leaflets extending toward the left ventricle side and being capable of opening and closing, and the anterior leaflet and the posterior leaflet being each provided on the tip side with a plurality of string-shaped members extending into the left ventricle, on a mitral valve using, and the mitral valve is configured to open when the string-shaped members are pulled toward a cardiac apex side by a sucking action of the pump, as disclosed by Iversen, to provide a mitral valve, an anterior leaflet, a posterior leaflet, left ventricle, cord-like tendons, chordae tendineae, and left atrium for valve repair devices and processes. One skilled in the art would recognize the value of the addition of a mitral valve, an anterior leaflet, a posterior leaflet, left ventricle, cord-like tendons, chordae tendineae, and left atrium for valve repair devices and processes. In regards to claim 20, Okayama does not disclose wherein the anterior leaflet and the posterior leaflet are held by a holder, and the holder is installed at a boundary portion between the left atrium and the left ventricle. Iversen discloses wherein the anterior leaflet and the posterior leaflet are held by a holder, and the holder is installed at a boundary portion between the left atrium and the left ventricle ([0173], “delivery member … can … include a suction device for holding valve tissue” Examiner notes that the anterior leaflet and the posterior leaflet are both made of valve tissue). Okayama and Iversen combined are considered analogous to the claimed invention because they are in the field of catheter simulators, heart models, and valve repair devices and processes. Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the applicant’s invention for a catheter simulator for practicing catheter manipulations in a state of holding a heart model in a container filled with a liquid, the heart model including a main body formed from an elastic material and including a left atrium and a left ventricle, with a mitral valve installed at a boundary portion between the left atrium and the left ventricle, wherein the container includes a holding part for holding the heart model, and an introduction part capable of inserting a catheter, a pump for circulating the liquid to be filled in the container into the heart model is connected to the container, the pump is intermittently driven so that a pulsatile flow flows from the left atrium toward the left ventricle in the heart model held in the container, and a catheter surgery, and a catheter can be practiced against the anterior leaflet and the posterior leaflet of the heart model held by the holding part, as disclosed by Okayama, the mitral valve including an anterior leaflet and a posterior leaflet, both the leaflets extending toward the left ventricle side and being capable of opening and closing, and the anterior leaflet and the posterior leaflet being each provided on the tip side with a plurality of string-shaped members extending into the left ventricle, on a mitral valve using, and the mitral valve is configured to open when the string-shaped members are pulled toward a cardiac apex side by a sucking action of the pump, wherein the anterior leaflet and the posterior leaflet are held by a holder, and the holder is installed at a boundary portion between the left atrium and the left ventricle, as disclosed by Iversen, to provide a mitral valve, an anterior leaflet, a posterior leaflet, left ventricle, cord-like tendons, chordae tendineae, and left atrium for valve repair devices and processes.

Response to Arguments Applicant's arguments filed March 26, 2026 have been fully considered but are not persuasive. Applicant amended claims 1, 2, 11-13, and 16 and added new claims 17-20. Claims 1-20 are pending in this application. With respect to amended claim 1, Applicant argues “neither Okayama nor Iverson, alone or in combination, teach or suggest each and every feature recited in Applicant's claim 1” (See Response under 37 C.F.R. 1.111, Remarks, Claim Rejections under 35 U.S.C. 103, page 7, paragraph 3.) Examiner acknowledges Applicant’s remarks. Regarding claim 1, Okayama discloses a heart model comprising ([0011], “an object of the present invention is to provide … a heart model”): a main body ([0020], “The … heart model … has a main body”) formed from an elastic material ([0111], “The … heart models … are formed from a material having elasticity”) and including a left atrium and a left ventricle ([0020], “The … heart model … has … a left atrium … and a left ventricle”), with a mitral valve installed at a boundary portion between the left atrium and the left ventricle ([0071], “there is no serious problem even if … a tricuspid valve … and a mitral valve are not formed inside the main body”); and a vena cava provided in the main body ([0020], “The … heart model … has a … venae cavae (superior vena cava and inferior vena cava) that are connected to the main body of heart”) and Iversen discloses wherein the mitral valve includes an anterior leaflet and a posterior leaflet ([0105], “the mitral valve … includes two leaflets, the anterior leaflet … and the posterior leaflet”), both the leaflets extending to the left ventricle side and capable of opening and closing ([0020], “Figure 3 is a … view of a … mitral valve with the leaflets closed”), and the anterior leaflet and the posterior leaflet are each provided on a tip side with a plurality of string-shaped members extending into the left ventricle ([0105], “The mitral valve … is anchored to the wall of the left ventricle … by … cord-like tendons that connect … the muscles … within the walls of the left ventricle … to the leaflets” Examiner notes that cord-like tendons are generally considered synonymous with string-shaped tendons.) and one terminal end of each of the string-shaped members is free ([0105], “mitral valve … is anchored to the wall of the left ventricle … by chordae tendineae” Examiner notes that chordae tendineae are string-shaped members.). In claim 1, Applicant’s reference to “one terminal end of each of the string-shaped members is free” is not implied in the Applicant’s specification. MPEP § 2111 discusses proper claim interpretation, including giving claims their broadest reasonable interpretation (“BRI”) in light of the specification during examination. Under BRI, the words of a claim must be given their plain meaning unless such meaning is inconsistent with the specification, and it is improper to import claim limitations from the specification into the claim. Applicant’s argument is not persuasive because the BRI is broader than what is argued. Therefore, the rejection of amended claim 1, as obvious over Okayama in view of Iversen is maintained. Consequently, the rejections of dependent claims 2-10 are maintained. With respect to amended claim 11, Applicant argues “neither Okayama nor Iverson, alone or in combination, teach or suggest each and every feature recited in Applicant's claim 11” (See Response under 37 C.F.R. 1.111, Remarks, Claim Rejections under 35 U.S.C. 103, page 8, paragraph 3.) Examiner acknowledges Applicant’s remarks. Regarding claim 11, Okayama discloses a mitral valve model installed at a boundary portion between a left atrium and a left ventricle of a heart model ([0071], “there is no serious problem even if … a tricuspid valve … and a mitral valve are not formed inside the main body”), formed from a hard material harder than a material constituting the heart model ([0116], “The material … may be any material harder than the material for forming … the heart model”) and Iversen discloses and comprising an anterior leaflet and a posterior leaflet formed from flexible members, with edge sides thereof bent to lie on top of each other ([0105], “the mitral valve … includes two leaflets, the anterior leaflet … and the posterior leaflet”), formed from flexible members ([0103], “Each of these valves has flexible leaflets”), with edge sides thereof bent to lie on top of each other ([0109], “the anterior leaflet … and the posterior leaflet … coapt” Examiner notes that coapt refers to fitting tightly together and the state of being joined together.), wherein the anterior leaflet and the posterior leaflet are mounted on a holder ([0173], “The delivery member … can … include a suction device for holding valve tissue” Examiner notes that the anterior leaflet and the posterior leaflet are both made of valve tissue.) the holder is installed at a boundary portion between the left atrium and the left ventricle ([0268], “a tortuous path is created with multiple holding points”), and the anterior leaflet and the posterior leaflet are each provided on the edge side with a plurality of string-shaped members ([0105], “The mitral valve … is anchored to the wall of the left ventricle … by … cord-like tendons that connect … the muscles … within the walls of the left ventricle … to the leaflets” Examiner notes that cord-like tendons are generally considered synonymous with string-shaped tendons.). MPEP § 2111 discusses proper claim interpretation, including giving claims their broadest reasonable interpretation (“BRI”) in light of the specification during examination. Under BRI, the words of a claim must be given their plain meaning unless such meaning is inconsistent with the specification, and it is improper to import claim limitations from the specification into the claim. Applicant’s argument is not persuasive because the BRI is broader than what is argued. Therefore, the rejection of amended claim 11, as obvious over Okayama in view of Iversen is maintained. Consequently, the rejection of dependent claim 12 is maintained. With respect to amended claim 13, Applicant argues “neither Okayama nor Iverson, alone or in combination, teach or suggest each and every feature recited in Applicant's claim 13” (See Response under 37 C.F.R. 1.111, Remarks, Claim Rejections under 35 U.S.C. 103, page 10, paragraph 5.) Examiner acknowledges Applicant’s remarks. Regarding claim 13, Okayama discloses a catheter simulator for practicing catheter manipulations in a state of holding a heart model in a container filled with a liquid ([0012], “the present invention provides a container for a catheter simulator comprising: an accommodating unit for accommodating a liquid, … the heart model is installed in the accommodating unit that is filled with a liquid”), the heart model including a main body formed from an elastic material ([0016], “The heart models … are formed from materials having elasticity”) and including a left atrium and a left ventricle ([0020], “The … heart model … has … a left atrium … and a left ventricle”), with a mitral valve installed at a boundary portion between the left atrium and the left ventricle ([0071], “there is no serious problem even if … a tricuspid valve … and a mitral valve are not formed inside the main body”), wherein the container includes a holding part for holding the heart model ([0011], “an object of the present invention is to provide a container for a … heart model”), and an introduction part capable of inserting a catheter ([0012], “the present invention provides … a installation part for inserting a catheter”), a pump for circulating the liquid to be filled in the container into the heart model is connected to the container ([0018], “the pump is connected to the container”), the pump is intermittently driven so that a pulsatile flow flows ([0124], “The pump … that is connected to the … model … is intermittently driven so as to generate a pulsatile flow”) from the left atrium toward the left ventricle in the heart model held in the container and Iversen discloses the mitral valve including an anterior leaflet and a posterior leaflet ([0105], “the mitral valve … includes two leaflets, the anterior leaflet … and the posterior leaflet”), both the leaflets extending toward the left ventricle side and being capable of opening and closing ([0020], “Figure 3 is a … view of a … mitral valve with the leaflets closed”), and the anterior leaflet and the posterior leaflet being each provided on the tip side with a plurality of string-shaped members extending into the left ventricle ([0105], “The mitral valve … is anchored to the wall of the left ventricle … by … cord-like tendons that connect … the muscles … within the walls of the left ventricle … to the leaflets” Examiner notes that cord-like tendons are generally considered synonymous with string-shaped tendons.), on a mitral valve using ([0105], “the mitral valve … includes two leaflets, the anterior leaflet … and the posterior leaflet”) and the mitral valve is configured to open when the string-shaped members ([0105], “Without the connection to the chordae tendineae … the mitral valve … would revert … back toward … the atrium”) are pulled toward a cardiac apex side by a sucking action of the pump ([0105], “The mitral valve opens … in response to pressure changes in the left atrium … and the left ventricle” Examiner notes that a pump relies on pressure differences to create suction.). MPEP § 2111 discusses proper claim interpretation, including giving claims their broadest reasonable interpretation (“BRI”) in light of the specification during examination. Under BRI, the words of a claim must be given their plain meaning unless such meaning is inconsistent with the specification, and it is improper to import claim limitations from the specification into the claim. Applicant’s argument is not persuasive because the BRI is broader than what is argued. Therefore, the rejection of amended claim 13, as obvious over Okayama in view of Iversen is maintained. Consequently, the rejections of dependent claims 14-20 are maintained. With respect to claim 3, Applicant argues “neither Okayama nor Iverson, alone or in combination, teach or suggest each and every feature recited in Applicant's claim 3” (See Response under 37 C.F.R. 1.111, Remarks, Claim Rejections under 35 U.S.C. 103, page 12, paragraph 3.) Examiner acknowledges Applicant’s remarks. Regarding claim 3, Okayama discloses wherein the string-shaped members are formed from a stretchable material ([0016], “The heart models … are formed from materials having elasticity” Examiner notes that elasticity implies that the material is stretchable.). MPEP § 2111 discusses proper claim interpretation, including giving claims their broadest reasonable interpretation (“BRI”) in light of the specification during examination. Under BRI, the words of a claim must be given their plain meaning unless such meaning is inconsistent with the specification, and it is improper to import claim limitations from the specification into the claim. Applicant’s argument is not persuasive because the BRI is broader than what is argued. Claim 3 is dependent on claim 1. Therefore, the rejection of claim 3, as obvious over Okayama in view of Iversen is maintained. With respect to claim 4, Applicant argues “neither Okayama nor Iverson, alone or in combination, teach or suggest each and every feature recited in Applicant's claim 4” (See Response under 37 C.F.R. 1.111, Remarks, Claim Rejections under 35 U.S.C. 103, page 12, paragraph 6.) Examiner acknowledges Applicant’s remarks. Regarding claim 4, Iversen discloses wherein the anterior leaflet and the posterior leaflet are held by a holder ([0173], “The delivery member … can … include a suction device for holding valve tissue” Examiner notes that the anterior leaflet and the posterior leaflet are both made of valve tissue.) and the holder is installed at a boundary portion between the left atrium and the left ventricle ([0268], “a tortuous path is created with multiple holding points”). MPEP § 2111 discusses proper claim interpretation, including giving claims their broadest reasonable interpretation (“BRI”) in light of the specification during examination. Under BRI, the words of a claim must be given their plain meaning unless such meaning is inconsistent with the specification, and it is improper to import claim limitations from the specification into the claim. Applicant’s argument is not persuasive because the BRI is broader than what is argued. Claim 4 is dependent on claim 1. Therefore, the rejection of claim 4, as obvious over Okayama in view of Iversen is maintained.
