| 摘要 |
The present invention is a shaped catheter having an atraumatic tip portion which facilitates ease of navigation through the patient's vascular system. The catheter includes a shape-region formed at or near the distal end of the catheter. The shape is formed by placing the catheter over a shaping tool that includes a die, heating the catheter to its softening point for a desired period of time, and then cooling the catheter. A shrink tubing may also be placed over the catheter after it is placed on the shaping tool and before heating to assist in achieving the desired shape.
