Abstract: An endoluminal prosthesis for deployment in a body which has a first tubular structure for stabilising the prosthesis, the first tubular structure being substantially concentric about a first axis and movable between a compact and an expanded state. The prosthesis also has a second tubular structure for supporting an artificial heart valve, the second tubular structure being substantially concentric about a second axis and moveable between a compact and an expanded state. The first axis and the second axis extend at different angles when the first and second structures are in the compact and/or expanded state. A third structure which is shape and/or length adjustable is positioned between the first and second structures.

Abstract: A stent (10) which may be used in the treatment of stenosis and particularly ostial stenosis. The stent (10) includes a flange member (15) which engages the surrounding wall of an ostium and anchors the stent (10) in its target vessel. A delivery system for a stent (10) is also disclosed, the delivery system including a membrane (109) or a compression member to hold an intraluminal stent (101) in a first radially compressed state until said stent (101) is delivered to a target site.
