ル。[Claims for Utility Model Registration] 1. A tube whose distal end is sealed, and a tube that is torn into a plurality of strips along the axis at the same position in the circumferential direction, each of which is bent radially with respect to the central axis. In a catheter in which one or more portions 3 are formed, a guide tube 4, which is a tube whose outer diameter is approximately equal to the inner diameter of the catheter and whose length reaches the front end of the bent portion, is disposed on the inner wall of the catheter near the rear end of the bent portion.
A catheter characterized by being inserted and fixed. 2 It is a tube with a sealed tip, and one or more bent parts 3 are formed by bending a plurality of band-like parts along the axis line at the same position in the circumferential direction radially with respect to the central axis line. In this catheter, a guide tube 4, which is a tube whose outer diameter is approximately equal to the inner diameter of the catheter and whose length reaches the front end of the bent part, is disposed on the inner wall of the catheter near the rear end of the bent part.
is inserted and fixed, and the tube has a sealed tip and has an outer diameter smaller than the inner diameter of the guide tube 4, and is configured such that an insertion tube 5 into which a stylet can be attached and detached can be inserted and detached into the inner cavity. A catheter characterized by:
