1. An endoluminal prosthesis comprising:
- a stent graft comprising a tubular graft wall, a stent, a main strand, a proximal strand perpendicular to the main strand and having first and second ends, and a distal strand perpendicular to the main strand and having first and second ends;
wherein the tubular graft wall defines an internal lumen of the stent graft and comprises a first surface and a second surface;
wherein the stent is positioned on the first surface of the tubular graft wall and comprises at least two proximal apices and at least three distal apices;
wherein the proximal strand is positioned on at least the first surface of the tubular graft wall with the first end connected to one of the at least two proximal apices of the stent and the second end connected to another of the at least two proximal apices of the stent;
wherein the distal strand is positioned on at least the first surface of the tubular graft wall with the first end connected to one of the least three distal apices of the stent and the second end connected to an another of the least three distal apices of the stent;
wherein the main strand is positioned longitudinally along one of the first and second surfaces of the tubular graft wall and connected to the proximal strand and the distal strand on one of the first and second surfaces of the tubular graft wall and moveable in at least a distal direction;
wherein movement of the main strand in the distal direction pulls the proximal strand distally to cause the at least two proximal apices of the stent to move inwardly toward each other and reduce a diameter of the tubular graft at the at least two proximal apices of the stent.

Abstract
Systems and methods of adjusting the diameter of an endoluminal prosthesis that allows for controlled radial deployment of the endoluminal prosthesis and the ability to revise the positioning of the endoluminal prosthesis after unsheathing. The endoluminal prosthesis includes a stent graft having a tubular graft wall, a stent, a main strand, a proximal strand, and a distal strand.

17. A system for controlled radial contraction and expansion of an endoluminal prosthesis, the system comprising:
-
a stent graft comprising a tubular graft, a stent connected to the tubular graft, a main strand, a proximal strand, and a distal strand; wherein the tubular graft wall defines an internal lumen of the stent graft and comprises a first surface and a second surface; wherein the stent is positioned on the first surface of the tubular graft wall and comprises at least two proximal apices and at least three distal apices; wherein the proximal strand is positioned on at least the first surface of the tubular graft wall and connected to the two proximal apices of the stent; wherein the distal strand is positioned on at least the first surface of the tubular graft wall and connected to at least two of the three distal apices of the stent; wherein the main strand is positioned along one of the first and second surfaces of the tubular graft wall and connected to the proximal strand and the distal strand on one of the first and second surfaces of the tubular graft wall and is configured to move in a proximal direction and a distal direction; wherein the main strand comprises a proximal end connected to the proximal strand and a distal manipulation end; wherein movement of the main strand in the distal direction reduces the diameter of the stent and an associated portion of the tubular graft and movement of the main strand in the proximal direction increases the diameter of the stent and an associated portion of the tubular graft from the reduced diameter. - View Dependent Claims (18, 19, 20)
