  • Publication number: 20260124432
    Abstract: This distal stabilizer used for catheter delivery in a biological lumen comprises a linear delivery member and a cylindrical part that extends from the distal end of the linear delivery member and that latches to the inner wall of the biological lumen. The cylindrical part has a structure in which cells 20 of a form surrounded by wire-shaped members are lined up along the long axis direction. At least one of the cells is an open cell having at least one free convex end 23. In the open cell, the wire-shaped member 22a that, from among the wire-shaped members forming the free convex end 23, extends in the direction in which the cells are lined up is disposed so as to be substantially parallel to the wire-shaped member 22c of another cell adjacent in the lateral direction with respect to the direction in which the cells are lined up.

  • Publication number: 20220233821
    Abstract: A distal stabilizer for use for catheter delivery in a biological lumen, the distal stabilizer comprising: a thread-like delivery member; and a locking device that extends from a distal end of the thread-like delivery member and is capable of locking onto an inner wall of the biological lumen with an expanding force. The distal stabilizer is usable in a catheter delivery operation including: releasing the locking device, which has been loaded in a first catheter while being in a reduced diameter state, from a distal end of the first catheter, thereby causing the locking device to lock onto the inner wall; and advancing a catheter including a second catheter having an inner diameter larger than the first catheter toward a distal side while the locking device remains locked on the inner wall.
