<p><P>PROBLEM TO BE SOLVED: To provide a stent for a vascular channel which is inserted into the vascular channel without producing a stress concentration zone in the vascular channel. <P>SOLUTION: A stent for a vascular channel 31 which is inserted into the vascular channel of a living body and holds the inserted vascular channel from its inside has a tubular member 33 which constitutes a passageway from one end to other end side. In the tubular member 33, low rigidity parts 35, 36 which are lower in rigidity than the central main body part are formed in one on a metallic thin wire 32 or a central main body part 34 which twists a polymer thread in a net-like shape, and on the both ends side of the central main body part 34. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
