<P>PROBLEM TO BE SOLVED: To provide a balloon catheter with a new structure, by which a balloon can be positioned in a circumferential direction with respect to body tubular tissue and inflated so as to be bent in a suitable direction conforming to the bending direction of the body tubular tissue. <P>SOLUTION: In the balloon catheter 10, a balloon 30 is attached in an externally inserted state to the distal end side of a catheter body 12 and a supply/drain passage 28 for supplying/sucking pressure fluid to/from the balloon 30 from the proximal end of the catheter body 12 is formed. A bent part 34 bent in the longitudinal direction by supplying pressure fluid via the supply/drain passage 28 and inflated is provided to the balloon 30, contrast markers 36 are provided to both end parts in the longitudinal direction and a part where the bent part 34 is externally inserted, respectively, in the part where the balloon 30 is externally inserted in the catheter body 12, and contrast shapes of the contrast markers 36 are varied in the circumferential direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
