Patent ID: 7905914

Claim:
A prosthesis assembly comprising: a proximal prosthesis having a proximal end and a distal end, the proximal prosthesis further having a proximal orifice at the proximal end to be located in and when expanded to be supported by a vascular vessel; at least one distal prosthesis having a proximal end and a distal end; the proximal prosthesis having at least two transversely placed tapering portions that extend from an intermediate portion to the distal end of the proximal prosthesis to form a bifurcated prosthesis; the proximal prosthesis also having at least one distal orifice at the distal end of at least one of the tapering portions which when expanded serves to receive the proximal end of the at least one distal prosthesis; wherein the proximal prosthesis and the at least one distal prosthesis each comprises an expandable stent constructed with a wire skeleton having one or more parts that extends from the respective proximal ends to the respective distal ends; at least one fabric layer over and/or in the wire skeletons of the expandable stents; and wherein a cross-sectional area of the at least one distal orifice when expanded is sufficiently less than that of the proximal end of the at least one distal prosthesis when expanded within the at least one distal orifice so as to form a seal between the proximal and distal prostheses.
