    Abstract: A catheter holder capable of stably holding a catheter on a body surface of a patient by facilitating catheter routing when the catheter is mounted on the body surface includes first and second components. The first component has a base portion configured to adhere to the patient's body surface and a receiving portion configured to receive a portion of a catheter disposed inside the patient's body and extending to outside of the body. The second component has a holding portion configured to hold the catheter and/or a connector connected to the catheter, with the second component being rotatably connected to the first component. The first or second component includes a catheter guide portion configured to bend the catheter, which extends from the receiving portion, toward the holding portion, and the catheter guide portion is formed with a crush prevention portion configured to prevent the catheter from being crushed.

    Abstract: A catheter shape retainer includes a retainer main body inserted and disposed in an inner lumen of a catheter to retain a cylindrical shape of the catheter, and a movement restrictor disposed closer to a distal portion of the retainer main body than a proximal portion of the retainer main body to restrict the catheter from moving toward the proximal portion of the retainer main body. When a portion of the retainer main body including the distal portion of the retainer main body is inserted into a living body, a portion of the retainer main body located outside the living body has a length longer than a total length of a puncture device.

    Abstract: In an in-vivo indwelling stent, a plurality of annular bodies formed in a circular shape with linear components are arranged in an axial direction, and adjacent annular bodies are connected by connection portions. Each of the annular bodies includes connection linear portions that connect one end side bent portions and other end side bent portions. One of the connection linear portions of the annular bodies located in a central portion of the stent includes axial linear portions that have one end side vertices of the one end side bent portions as starting ends and extend so as to be parallel to the axial direction of the stent, and bent portions that have starting ends at terminal ends of the axial linear portions and extend in a circumferential direction of the stent.

    Abstract: A medical device for crushing an object in a body lumen, the medical device including: an elongated shaft portion rotatably driven; a crushing unit provided with bendable wire rods and rotatable together with the shaft portion; and a sliding unit fixed to each of end portion of the wire rods on at least one of a distal side of and a proximal side of the wire rods and is interlocked with the shaft portion so as to be slidable in an axial direction of the shaft portion. The shaft portion is provided with contact portions that come into contact with the sliding unit during rotation and limit relative rotation of the shaft portion and the sliding unit. After the sliding unit is attached to the contact portions, the sliding unit rotates in the same direction as the shaft portion along with the rotation of the shaft portion.

    IPC: A61B17/3207

    Abstract: A medical device is disclosed that can effectively destroy an object in a biological lumen, a method for controlling rotation of the medical device, and a rotation controller. The medical device to be inserted into a biological lumen to destroy a thrombus in the biological lumen includes a long shaft portion that is rotationally driven, a drive unit that rotates the shaft portion, a breaking member that is provided at a distal portion of the shaft portion and is rotatable, and a control unit that controls the rotation of the drive unit, in which the control unit controls the drive unit to repeat the rotation while interposing a stop of the rotation between rotations of the drive unit.

    Abstract: This in-vivo indwelling stent has annular bodies constituted by a plurality of annular bodies arranged in the axial direction, and connection portions. The plurality of annular bodies includes first pattern annular bodies and second pattern annular bodies that are alternately arranged. The first pattern annular bodies each have an endless zigzag linear shape including one-end-side apexes, other-end-side apexes, and curved linear bodies that connects the apexes and protrudes in a first circumferential direction. The second pattern annular bodies each have an endless zigzag linear shape including one-end-side apexes, other-end-side apexes, and a plurality of curved linear bodies that connects the apexes and protrudes in a second circumferential direction. The one-end-side apex and the other-end-side apex of adjacent annular bodies are connected to each other with the connection portion.
