<P>PROBLEM TO BE SOLVED: To provide a thrombus suction catheter which can absorb vibrations during inserting the catheter and can improve the blood vessel following performance and the kink resistance by making a lengthened intermediate part accomplish an interference action. <P>SOLUTION: In the thrombus suction catheter (1), a shaft tube (2) is made up of three kinds of tubes with varied hardness, of a proximal part (3), an intermediate part (4) and a distal part (5). A reinforcing material (7) is mounted on the inner wall surface of the proximal part (3) to keep it from coming into contact with a liquid, and a guide wire tube (6) is mounted on the distal part (5). Each of the proximal part (3) and the intermediate part (4) has a suction lumen (11) while the distal part (5) has a guide wire lumen (10) and the suction lumen (11). The distal part (5) is formed out of a soft tube with its hardness D2 being 40-75 when the hardness D1 of the intermediate part (4) is 100. <P>COPYRIGHT: (C)2007,JPO&INPIT |
