Abstract

Abstract A sleeve for attaching a medical balloon to a catheter utilizing a balloon (8). The sleeve comprises a plurality of co-extruded and coextensive layers of different polymeric materials (20A, 20B) at least one of which is a base structural layer (20B) and the other of which (20A) is formed of polyethylene and copolymers thereof or of Selar. The base structural layer is thicker than the other layer. The diameter of the catheter at the joint (10, 11) is substantially the same as the tube.
