Patent ID: 8663307

Claim:
An endoluminal prosthesis comprising: a tubular graft having a length and comprising: a graft material, a proximal end having a proximal opening, and a distal end having a distal opening, wherein the proximal and distal openings and the graft material form a lumen for the flow of body fluids therethrough; an annular support member attached to the graft material, but otherwise being unconnected to another annular support member, said annular support member comprising a closed ring defining a circumference and an axis extending longitudinally therethrough, a plurality of apices coupled by a plurality of spokes, wherein the apices comprise alternating crests and troughs arranged to hold the graft material in a leak resistant sealing engagement with the inner wall of a body lumen; wherein at least one of the troughs extends axially beyond an other of the troughs; wherein the troughs of the annular support member comprise a plurality of alternating longer troughs and shorter troughs; wherein said annular support member corresponds to a first annular support member and further comprising a second annular support member comprising a plurality of second spokes coupled by a plurality of second apices to form a second ring, wherein the second annular support member is attached to the graft material to define a circumferential area of the graft material around the second annular support member, but otherwise being unconnected to said first annular support member, and wherein the one of the longer troughs of the first support member is attached to the graft material within the circumferential area of the second support member.
