| 摘要 |
The catheter of the present invention comprises a body portion, a distal portion and an internal lumen and at least the above body portion includes a super-elastic metallic tube. This catheter has a high efficiency of transmitting the pushing force given at its proximal end (pushability) and a high torque transmission efficiency. Furthermore, since the body portion of the catheter includes a super-elastic metallic tube, the wall thickness of the body portion can be made sufficiently thin and a catheter with a smaller diameter can be formed.
