| 摘要 |
<p>A dilatation catheter has a tubular proximal shaft (15) having relatively high rigidity, a tubular distal shaft (13) having rigidity lower than that of the proximal shaft (15), a tubular intermediate section (14) interposed between the proximal shaft (15) and the distal shaft (13), a hub (16) mounted on the proximal end portion of the proximal shaft (15), a balloon (12) arranged on the distal end portion of the distal shaft (13) so as to be in fluid communication with the distal shaft (13), and an inner shaft (11) into which a guide wire can be inserted. The distal end portion of the proximal shaft (15) can be inserted into the intermediate section (14) to form an insertion portion (152) having a spiral slit. <IMAGE></p> |
