IMPROVED DELIVERY SYSTEM ASSEMBLIES FOR IMPLANTABLE MEDICAL DEVICES

摘要

An inner member of an improved assembly for a delivery system includes a first segment formed by a multi-lumen tubing surrounded by a braided tubing, and a second segment formed by a single-lumen tubing that extends within a distal portion of the braided tubing. The single-lumen tubing accommodates an antenna of a medical device, is in fluid communication with three lumens of the multi-lumen tubing, and opens into a flared distal end of the inner member. A distal-most portion of an outer tube of the system contains the flared distal end and an enclosure of the medical device abutting the distal end. A pull wire of the assembly extends within another lumen of the multi-lumen tubing, and is coupled to a pull band mounted in a cone member that forms the flared distal end.
