Elephant trunk thoracic endograft and delivery system
First Claim
1. A prosthesis delivery system comprising:
- a stent/graft composite prosthesis comprising a radially expandable stent and an elongated graft secured to said stent; and
a deployment device comprising;
an elongated outer sheath for overlying said prosthesis, said outer sheath being retractable with respect to said prosthesis for allowing radial expansion of said prosthesis; and
a stent retaining member for maintaining an end of said prosthesis in a radially compressed state, said retaining member being separately removable from said end for allowing said radial expansion of said end of said prosthesis.

Abstract
A delivery system for delivering a device within a body lumen. The delivery system includes a self-expanding stent/graft composite prosthesis and a deployment device. The deployment device includes an outer sheath which overlies the graft, and a stent retaining means for maintaining the one end of the stent in a radially compressed state. The outer sheath is retractable with respect to the graft, and the stent retaining means is removable to allow the stent end to radially expand. The deployment device may further include an inner sheath to overlie the composite and is retractable with respect to the composite. An endoluminal prosthesis including a graft attached to one stent and a second stent unattached within the graft lumen.
