Abstract
A method of manufacturing an elongate shaft for delivery of a medical device may include disposing a polymeric sheath having a lumen extending therethrough over a mandrel; sliding a proximal portion of the polymeric sheath into a lumen of a metallic tubular member; placing a polymeric tubular member over the distal portion of the polymeric sheath and a distal portion of the metallic tubular member; fixedly attaching a proximal coupler to a distal end of a longitudinal support filament; inserting a proximal end of the longitudinal support filament between the polymeric sheath and the polymeric tubular member to position the longitudinal support filament alongside the distal portion of the metallic tubular member and a distal portion of the polymeric sheath; and reflowing the polymeric tubular member to secure the longitudinal support filament relative to the polymeric sheath and the metallic tubular member.
