Abstract:
1. A prosthesis, comprising: a biocompatible tubular graft having a lumen extending at least longitudinally therein, the lumen having a maximum diameter; an expandable stent engageable with said graft, wherein said stent is capable of maintaining at least a portion of said lumen of said graft patent; a fenestration disposed in the graft having a variable size and communicating with said lumen, and adapted to receive a branch graft, the fenestration having a maximum diameter less than the maximum diameter of the lumen; and, a radially elastic frame comprising a single wire having overlapping ends disposed at least partially about said fenestration, and at least partially controlling the variable size of said fenestration; where the diameter of the frame elastically expands in response to the application of a mechanical expanding force and contracts upon removal of the expanding force to maintain a fluid tight seal with the branch graft.
