Abstract
There is disclosed a novel endovascular prosthesis that has an improved rotational range of proper placement of the prosthesis with respect to the opening of the aneurysm and provides improved flexibility with respect to longitudinal positioning of the device in the artery. This provides the clinician with a significant advantage over the prior art devices described above. The present elongate 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 the wall of the vascular lumen such as an artery. The endovascular prosthesis further comprises a retractable leaf portion attached to the first expandable portion; the retractable leaf portion serves to facilitate stasis and thrombotic occlusion of the aneurysm. The retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion.
