Patent ID: 8840657

Claim:
A stent graft comprising: a tubular graft comprising a socket arrangement into which may be placed a second stent graft, the socket arrangement comprising: a first ring and second ring attached to the tubular graft and each comprised of a wire terminating in loops, the second ring spaced apart from the first ring; a stent comprising a single length of a resilient wire, the resilient wire comprising a zig zag form defined by a plurality of struts and a bend between each strut and an adjacent strut, the resilient wire comprising a first end and a second end, each end comprising a terminal strut; the terminal struts of the first end and the second end each terminating in a terminal loop, the terminal loops preventing the resilient wire from digging into a vasculature into which the stent graft is deployed; the stent being attached in a substantially cylindrical form around an outside of the tubular graft between the first ring and the second ring, the first end and the second end of the stent overlapping each other so that at least the terminal struts overlap each other along their entire length; and wherein the stent is sized in the cylindrical form at rest to be smaller than the diameter of the tubular graft and therefore smaller than the diameter of the first ring and second ring, thereby providing a compressive effect on the tubular graft to keep tension on the second stent graft and provide firm locking for the second stent graft.
