Patent ID: 8449600

Claim:
A leg extension stent graft comprising a tubular body of a biocompatible graft material, the tubular body comprising a first end with an outside sealing surface, a plurality of self-expanding stents connected to the tubular body along the length thereof with at least one self-expanding stent within the tubular body at the first end, the tubular body comprising a second end comprising a connection region, the connection region comprising a flared stent defining an external frusto-conical surface extending from the second end of the tubular body, the flared stent comprising a self expanding stent being formed from a resilient wire, the flared stent comprising a frusto-conical configuration with a narrower first end and a wider second end, the narrower first end being connected to the second end of the tubular body, the resilient wire comprising a plurality of struts, a first bend between each strut at the first end of the flared stent and a second bend between each strut at the second end of the flared stent and further including a wire ring at the second end of the connection region, the wire ring being fastened to the second bends of the flared stent to assist the flared stent to maintain the frusto-conical configuration, the first bends being fastened to the second end of the tubular body, the flared stent thereby providing a connection arrangement when the connection region of the leg extension stent graft is engaged within an iliac stent graft.
