Process for making a catheter
First Claim
1. A method for forming a tubular member for a medical device comprising the steps of:
- providing a tubular member of a plastic material, said tubular member having a wall with a surface and a length, andapplying a compressive force to one side of the wall of the tubular member at a region of the tubular member along said length, said compressive force being sufficient to reform said material of said tubular member to impart a contour to said surface.

Abstract
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.

12. A method for forming a tubular member for a medical device comprising the steps of:
-
providing a tubular member of a plastic material, said tubular member having a wall with an inner surface, an outer surface and a length; and applying a compressive force to the outer surface of the wall of the tubular member at a region of the tubular member along said length, said compressive force being sufficient to reform said material of said tubular member to impart a contour to said surface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
