Endovascular prosthesis
First Claim
1. A prosthesis for endovascular blocking of an aneurysmal opening, the prosthesis comprising:
- a body having a promixal end, a distal end and at least one expandable portion disposed therebetween, the at least one expandable portion being expandable from a first, unexpanded state to a second, expanded state with a radially outward force thereon to urge the first expandable portion against a vascular lumen, and a leaf portion attached to the body, the leaf portion being independently moveable with respect to the body.

Abstract
A novel endovascular approach useful in the treatment of aneurysms, particularly saccular aneurysms. The present endovascular prosthesis comprises a leaf portion capable of being urged against and blocking the opening of the aneurysm thereby leading to obliteration of the aneurysm. The leaf portion is attached to, and independently moveable with respect to, a body comprising at least one expandable portion. Thus, the body serves the general purpose of fixing the endovascular prosthesis in place at a target body passageway in the vicinity at which the aneurysm is located and the leaf portion serves the purpose of blocking the aneurysmal opening thereby leading to obliteration of the aneurysm. A method of delivering and implanting the endovascular prosthesis is also described.

26. A method for endovascular blocking of an aneurysmal opening with a prosthesis comprising:
- a body having a promixal end, a distal end and at least one expandable portion disposed therebetween, and a leaf portion attached to the body, the method comprising the steps of;
disposing the prosthesis on a catheter;
inserting the prosthesis and catheter within a body passageway by catheterization of the body passageway;
translating the prosthesis and catheter to a target body passageway at which the aneurysm opening is located;
exerting a radially outward expansive force on the at least one expandable portion such that the at least one expandable portion is urged against the target body passageway. urging the leaf portion against the aneurysmal opening thereby blocking the aneurysmal opening.
- a body having a promixal end, a distal end and at least one expandable portion disposed therebetween, and a leaf portion attached to the body, the method comprising the steps of;

27. A prosthesis for endovascular blocking of an aneurysmal opening, the prosthesis comprising:
-
a body having a longitudinal axis comprising at least one expandable portion, the at least one expandable portion being expandable from a first, unexpanded state to a second, expanded state with a radially outward force thereon to urge the first expandable portion against a vascular lumen, and a leaf portion attached to the body, the body being flexible between;
(i) a first position in which the at least one expandable portion and the leaf portion are aligned along the longitudinal axis, and (ii) a second position in which the at least one expandable portion and the leaf are unaligned along the longitudinal axis.
