A hybrid prosthesis (100) for deployment in a body vessel includes a tubular stent body (110) comprising a wire (105) comprising a shape memory alloy, where the tubular stent body (110) has a self-expanding portion (110a) comprising a distal portion (115) of the wire (105) and a balloon-expandable portion (110b) comprising a proximal portion (120) of the wire (105). The shape memory alloy comprises an A f of less than 37°C in the self-expanding portion (110a) and an A s of greater than 37°C in the balloon-expandable portion (110b). |
