materials, and a heart model for a catheter simulator includes a main body of heart and coronary arteries laid along the surface of the main body of heart, in which a portion of the coronary arteries is attachable and detachable. ## Claims ### Claim 1 An organ model for a catheter simulator, the organ model comprising: at least one of a simulated organ or a simulated blood vessel, both being formed from an elastic material, wherein a portion of the simulated organ or a portion of the simulated blood vessel is attachable and detachable. ### Claim 2 (depends on 1) The organ model for a catheter simulator according to claim 1, wherein the elastic material has X-ray transmissibility, and a portion of the simulated organ or a portion of the simulated blood vessel, both being attachable and detachable, includes an X-ray opaque portion. ### Claim 3 (depends on 1) The organ model for a catheter simulator according to claim 1, wherein a portion of the simulated organ or a portion of the simulated blood vessel, both being attachable and detachable, is a portion of a simulated blood vessel (vascular part), the vascular part includes an opening at both ends, and the two ends of the vascular part are connected to a mounting unit of the simulated blood vessel. ### Claim 4 (depends on 2) The organ model for a catheter simulator according to claim 2, wherein a portion of the simulated organ or a portion of the simulated blood vessel, both being attachable and detachable, is a portion of a simulated blood vessel (vascular part), the vascular part includes an opening at both ends, and the two ends of the vascular part are connected to a mounting unit of the simulated blood vessel. ### Claim 5 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein when the two ends of the vascular part are connected to the mounting unit of the simulated blood vessel, the inner diameter of portions other than the vascular part in the simulated blood vessel approximately coincides with the inner diameter of the vascular part. ### Claim 6 (depends on 4) The organ model for a catheter simulator according to claim 4, wherein when the two ends of the vascular part are connected to the mounting unit of the simulated blood vessel, the inner diameter of portions other than the vascular part in the simulated blood vessel approximately coincides with the inner diameter of the vascular part. ### Claim 7 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein the mounting unit of the simulated blood vessel has, at both ends, an edge serving as a connection unit to the vascular part, the region between the edges is continued in any of the bottom, the upper section, or the lateral section, or in a portion, even in a state of having the vascular part removed, and the distance between the edges is shorter than the length of the vascular part. ### Claim 8 (depends on 4) The organ model for a catheter simulator according to claim 4, wherein the mounting unit of the simulated blood vessel has, at both ends, an edge serving as a connection unit to the vascular part, the region between the edges is continued in any of the bottom, the upper section, or the lateral section, or in a portion, even in a state of having the vascular part removed, and the distance between the edges is shorter than the length of the vascular part. ### Claim 9 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein the mounting unit of the simulated blood vessel has, at both ends, an edge serving as a connection unit to the vascular part, and the inner surface of the edge is elastically adheres closely to the outer surface of the edge of the vascular part. ### Claim 10 (depends on 4) The organ model for a catheter simulator according to claim 4, wherein the mounting unit of the simulated blood vessel has, at both ends, an edge serving as a connection unit to the vascular part, and the inner surface of the edge is elastically adheres closely to the outer surface of the edge of the vascular part. ### Claim 11 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein the thickness of a side wall of the vascular part is thinner than the thickness of a side wall of a portion other than the vascular part in the simulated blood vessel. ### Claim 12 (depends on 4) The organ model for a catheter simulator according to claim 4, wherein the thickness of a side wall of the vascular part is thinner than the thickness of a side wall of a portion other than the vascular part in the simulated blood vessel. ### Claim 13 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein the organ model is a heart model, the heart model has a main body of heart and coronary arteries laid along the surface of the main body of heart, and the vascular part is a coronary artery part. ### Claim 14 (depends on 4) The organ model for a catheter simulator according to claim 4, wherein the organ model is a heart model, the heart model has a main body of heart and coronary arteries laid along the surface of the main body of heart, and the vascular part is a coronary artery part. ### Claim 15 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein the heart model has an aorta protruding toward the interior of the main body of heart; and an aortic valve positioned at the tip of the aorta. ### Claim 16 (depends on 3) The organ model for a catheter simulator according to claim 3, wherein a portion corresponding to the vascular wall of the vascular part has a multiple structure with a double or higher structure. ### Claim 17 (depends on 3) The organ model for a catheter simulator according to claim 3, further comprising an auxiliary part, the auxiliary part being a tubular body to be inserted inside the vascular part. ### Claim 18 (depends on 11) The organ model for a catheter simulator according to claim 11, wherein the auxiliary part has a diseased portion formed therein, the diseased portion having a smaller diameter than other regions, and in a state of having the auxiliary part inserted inside the vascular part, a gap is produced between the outer surface of the diseased portion and the inner surface of the vascular part. ### Claim 19 (depends on 12) The organ model for a catheter simulator according to claim 12, wherein at least one of the auxiliary part or the vascular part includes a small hole or a slit continuing from a gap produced between the outer surface of the diseased portion and the inner surface of the vascular part, or both of the small hole and the slit. ### Claim 20 (depends on 11) The organ model for a catheter simulator according to claim 11,
