Abstract

A delivery system including a restraining member maintains a collapsed implant in its collapsed state for delivery through a small passageway to a desired site in a mammalian body. Once the implant is positioned at the desired site, the restraining member is released so that the stent may expand or be expanded to its expanded state. In a preferred embodiment, the restraining member comprises a sheet of material that surrounds at least a portion of the collapsed stent. Portions of the restraining member are releasably coupled to one another with a low profile thread-like member or suture.

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of application Ser. No. 09 / 985,498, filed Nov. 5, 2001 which is a continuation of application Ser. No. 08 / 772,373, filed Dec. 23, 1996 and now issued as U.S. Pat. No. 6,352,561.BACKGROUND OF THE INVENTION

[0002] 1. Technical Field

[0003] This invention relates generally to implants for repairing ducts and passageways in the body. More specifically, the invention relates to implant deployment apparatus.

[0004] 2. Background Art

Shortcomings of this procedure include the morbidity and mortality associated with surgery, long recovery times after surgery, and the high incidence of repeat intervention needed due to limitations of the graft or of the procedure.

[0006] Vessels thickened by disease may be treated less invasively...
