Abstract
A stent graft assembly for use in placing a stent graft in a vessel of a patient comprising a balloon delivery catheter having a distal extremity and having an inflatable balloon on the distal extremity. A stent graft disposed over the inflatable balloon. The stent graft comprises a stent and a graft in the form of a polymeric sleeve extending over at least a portion of the graft. The graft has first and second ends. First and second expandable security rings are disposed over the first and second ends of the graft and serve to secure the first and second ends of the graft to the stent to prevent inadvertent displacement of the graft with respect to the stent during deployment of the stent graft into the vessel of the patient.
