<P>PROBLEM TO BE SOLVED: To provide a medical appliance allowing suitable improvement of kink resistance in a configuration to utilize a metal tube part in a portion inserted into a living body. <P>SOLUTION: A metal joint ring 42 and a metal reinforcing coil 43 are embedded in a resin layer 41 to form the outer tube part 31. The reinforcing coil 43 is formed in a coil state wherein the axial direction becomes the long direction by making a stainless steel metal wire spirally round, and rigidity of the reinforcing coil 43 is set to be lower than the joint ring 42. The reinforcing coil 43 extends such that a near end part is present in a position of an outer opening 34 and that a remote end part is present on the remote side of the joint ring 42, and is provided over the approximate whole of the outer tube part 31. In the configuration, the reinforcing coil 43 extends toward the remote side from inside the joint ring 42. <P>COPYRIGHT: (C)2012,JPO&INPIT |
