REPOSITIONABLE DIAMETER CONSTRAINTS
First Claim
1. A system for deploying an endoluminal prosthesis, the system comprising:
- a graft comprising biocompatible material having at least one lumen extending therethrough;
a rotatable cannula extending at least partially through the graft lumen; and
a suture having a first portion and a second portion, the first portion being coupled to the rotatable cannula within the graft lumen and the second portion being coupled to the graft, wherein the lengths of the first and second portions adjust in response to rotation of the rotatable cannula to vary a diameter of the graft.

Abstract
An endoluminal prosthesis includes an expandable stent graft that includes a cannula extending through a lumen of the stent graft. A suture is threaded along the perimeter of the graft through openings therein, with an inner end of the suture mounted to the cannula. The cannula is rotatable relative to the graft to wind or unwind the suture around the cannula and cause the graft to become compressed when wound or allow the graft to expand when unwound. The cannula includes an attachment member for retaining an inner end of the suture, and the attachment member can release the inner end of the suture when adjustment of the graft diameter is no longer desired.

9. A method for delivering an endoluminal prosthesis, the method comprising the steps of:
-
locating, within a patient'"'"'s body, an endoluminal prosthesis having a graft comprising biocompatible material having at least one lumen extending therethrough, wherein a cannula extends at least partially through the graft lumen and a suture is at least partially wound about the cannula and at least partially mounted about a perimeter of the graft; rotating the cannula in a first direction; in response to rotating the cannula in the first direction, unwinding a portion of the suture; expanding the graft outwardly; rotating the cannula in a second direction that is opposite the first direction; in response to rotating the cannula in the second direction, winding a portion of the suture about the cannula; and reducing the diameter of the graft. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
