20160121081 | Catheter - A guide wire port is formed in a midway position, in an axial line direction, of an outer shaft. A core wire extending across the guide wire port is provided in an outer tube hole of the outer shaft. The core wire has a leading end side area positioned further to a leading end side than the guide wire port and a tapered area provided on a base end side of the leading end side area. The tapered area has a first tapered area including a same position as the guide wire port in the axial line direction and a second tapered area provided continuously from a base end side of the first tapered area. A rate of increase of a transverse cross-sectional area from the leading end side toward the base end side is larger in the first tapered area than in the second tapered area. | 05-05-2016 |
20130237962 | CATHETER ASSEMBLY - Provided is a catheter assembly that can increase the degree of freedom for selecting a guide wire to be used. The catheter assembly includes an outer catheter and an inner catheter. The outer catheter is a catheter for introducing a balloon catheter or the like to an affected area and the inner catheter is an insertion-assisting tool that assists insertion by preceding the insertion of the outer catheter when being inserted in a human body. An inner opening by which a guide wire tube hole of the inner catheter is opened at a proximal end side and an outer opening by which the outer tube hole of the outer catheter is opened at a proximal end side are formed at the middle position in the axial line direction, and the openings are formed at an angle with respect to the axial line directions at positions on the same line. | 09-12-2013 |
20090264865 | INSERTION ASSISTING TOOL FOR CATHETER, CATHETER ASSEMBLY, AND CATHETER SET - An insertion assisting tool inserted into a catheter and positioned ahead of the catheter is provided so as to assist an insertion of the catheter. The insertion assisting tool includes: a distal end portion whose end is tapered and which has a guide wire lumen opening at a tip end and a proximal end of the distal end portion; and a shaft extending from a part of a proximal-end surface of the distal end portion to a proximal end of the insertion assisting tool. | 10-22-2009 |
