1. A method of manufacturing an elongate shaft for delivery of a medical device, comprising:
extruding a polymeric tubular member and a longitudinal support filament over a first polymeric sheath, while the first polymeric sheath is disposed on a mandrel, to form a composite tubular member;
removing the mandrel from within the composite tubular member;
sliding a metallic tubular member over a second polymeric sheath and securing a distal end of the second polymeric sheath to a distal end of the metallic tubular member;
placing the composite tubular member, with the mandrel removed, over a distal portion of the metallic tubular member; and
reflowing a proximal portion of the polymeric tubular member onto the distal portion of the metallic tubular member to secure the longitudinal support filament relative to the metallic tubular member.
