摘要：
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, specifically to an endovascular prosthesis and a method for delivery thereof. Elongate endovascular prosthesis comprises a first expandable portion and retractable leaf portion attached to the first expandable portion. First expandable portion is expandable from a first, unexpanded state to a second, expanded state to urge the first expandable portion against vascular walls. Retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion. Retractable leaf portion configured such that a pair of ribs attached on opposite sides of a longitudinally straightened 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 a second embodiment of the elongate 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 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. Method for delivering said endovascular prosthesis to a bifurcated artery having an aneurysm located at a junction of a main passageway, a first passageway and a second passageway, comprises the following steps: (a) placing a guidewire and delivery catheter in a first passageway such that the guidewire emanates from the delivery catheter (b) passing a combination of the endovascular prosthesis interconnected to a delivery device through the delivery catheter such that the first end of the endovascular prosthesis is urged against a portion of the first passageway (c) withdrawing the guidewire from the first passageway (d) placing the guidewire
