Abstract
The invention is directed to a method of forming a distal tip on a catheter. The method includes defining an area on the distal end of a polymeric tube, creating at least one void by removing at least some of the material within the area, and sealing the cut edge closed. The area is defined by a boundary, which includes a first location on the distal tip, a second location on the distal tip radially spaced apart from the first location, and a third location proximal to the distal tip. The preferred area is a cut having a V-shape. This method creates a superior catheter tip profile, specifically for soft tips.
