Abstract

The present invention relates to an endovascular prosthesis. The endovascular prosthesis comprises a first expandable portion expandable from a first, unexpanded state to a second, expanded state to urge the first expandable portion against a vascular ¥ lumen and a retractable leaf portion attached to the first expandable portion. The retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion. In one preferred embodiment of the present endovascular pros thesis, the retractable leaf portion is configured such that a pair of ribs attached on opposite sides of a longitudinally straightened o configuration of the spine portion in a plane of view normal to a central axis of the prosthesis defines a shape, in two dimensions, that is substantially non-circular. In another preferred embodiment of the present endovascular prosthesis, the retractable leaf portion is configured such that a pair of ribs attached on opposite sides of a longitudinally straightened configuration of the spine portion in o a plane of view normal to a central axis of the prosthesis defines a shape, in two dimensions, through which one straight line can be translated from one side to the other side of the shape so as to traverse the shape only once at every point along the shape. The rib portions of the present endovascular prosthesis can be designed so as to provide an improved rotational range of proper placement of the prosthesis with respect to the opening of the aneurysm.
