1. A patient-specific prosthesis for implantation at a treatment site in a patient, the prosthesis comprising:
a) a tubular graft;
b) a fenestration disposed in the tubular graft, the fenestration corresponding to a predicted branch blood vessel location;
c) a coupling member disposed about the fenestration, the coupling member including a coil configured to (a) expand from a first configuration to a second configuration in response to the application of an expanding force, and (b) contract to a third configuration upon removal of the expanding force;
d) a shape memory core disposed in the coil; and
e) a branch stent configured to be coupled to the fenestration, the branch stent including an engagement portion for engaging with the coupling member, and a flexible tail portion extending from the engagement portion, wherein the engagement portion of the branch stent includes a proximal portion having a first diameter, an intermediate portion having a second diameter, and a distal portion having a third diameter, the second diameter less than the first diameter and the third diameter in an expanded state.
