Appl. No.:

11/265631

Inventors:

Paul R. Seyler - Flagstaff AZ, US

Assignee:

Machine Solutions, Inc. - Flagstaff AZ

International Classification:

B21D 39/00

B21D 41/00

US Classification:

29508, 29282, 292835, 72402

Abstract:

A method of sheathing a stent including the steps of providing a stent assembly including a catheter member and a stent member disposed about the catheter member; placing a first sheath film adjacent one side of the stent assembly; placing a second sheath film adjacent an opposite side of the stent assembly, and compressing the stent assembly, whereby the first and second sheath films move toward each other and substantially surround the stent assembly. The first and second sheath films are provided in rolls. Compressing is implemented by a radial compression mechanism. The first and second sheath films pass through the radial compression mechanism. Compressing sheaths the stent assembly and crimps the stent onto the catheter. As an alternative to two sheath films, a single film may be used, whereby compressing surrounds the stent assembly with the single sheath film. Also disclosed in an apparatus for sheathing a stent, including a compressing mechanism; a sheath film supply; a film feeder for moving at least one sheath film from the film supply through the compressing mechanism, and a stent input system for moving a stent assembly into the crimping mechanism.
