Abstract
A catheter incorporating an insert molded tip and an improved method of manufacture that is simple, efficient, and significantly reduces current scrap rates for soft tip attachment to catheters. One catheter shaft embodiment includes a counterbored distal portion having anchor holes through the wall of the catheter body in this distal portion. In another embodiment, the catheter shaft has a reduced diameter portion including anchor holes. In yet another embodiment the catheter shaft has external longitudinal and external grooves. The tip is injection molded onto the body with tip material filling the counterbore, reduced diameter portion, anchor holes, and grooves to form integral anchors to secure the tip.
