Patent ID: 8894701

Claim:
A hybrid prosthesis for deployment in a body vessel, the prosthesis comprising: a tubular stent body comprising a wire comprising a shape memory alloy, the tubular stent body having a self-expanding portion comprising a distal portion of the wire and a balloon-expandable portion comprising a proximal portion of the wire, wherein the shape memory alloy consists of a single share memory alloy comprising an A f of less than 37° C. in the self-expanding portion and an A s of greater than 37° C. in the balloon-expandable portion, wherein the distal portion of the wire has a helical configuration comprising bent wire portions alternating with straight wire portions in a helical zigzag pattern about a longitudinal axis of the stent body, the helical zigzag pattern extending along an entire length of the distal portion, and wherein the proximal portion of the wire has a ring-like configuration including one or more rings centered about a longitudinal axis of the stent body, each of the one or more rings including bent wire portions alternating with straight wire portions in a circumferential zigzag pattern about the longitudinal axis wherein the hybrid prosthesis is a side arm prosthesis deployable in a branch vessel body lumen.
