Vascular access catheter and methods for manufacture thereof |
摘要 |
An intravascular catheter for providing access to distal vascular sites. The intravascular catheter comprises an elongate shaft with a lumen extending therethrough. The elongate shaft is comprised of a composite construction and has a proximal relatively stiff section, a distal section relatively more flexible than the proximal section, and an intermediate section between the proximal and the distal sections that provides a transition in flexibility between the proximal section and the distal section. The distal section has surface contours that impart flexibility to the distal section. A method for processing a tubular member with surface contours for use in a medical device, such as a catheter or guide wire, is also provided.
