Publication number: 20160113797Abstract: Stent delivery system and method of manufacturing same. The stent delivery system comprises an inner catheter with an enlarged tip disposed at the distal end thereof.

Patent number: 8388676Abstract: A temporary stent endoprosthesis that does not require an interventional procedure for removal. The disintegrating stent is preferably made from a bioabsorbable polymer, such as by braiding polymer monofilaments into a tubular mesh shape, and the polymer has fracture initiation sites within it that promotes the disintegration of the stent into small pieces that are harmlessly transported out of the body by the vessel contents. Fracture initiation sites may be created by controlling the heterogenous structure of amorphous and crystalline regions, by introducing internal or surface fracture initiation sites, or use of multiple strands with small section size.Type: GrantFiled: December 23, 2003Date of Patent: March 5, 2013Assignee: Boston Scientific Scimed, Inc.Inventor: Jonathan S.
