Medical device for treating a heart valve insufficiency
First Claim
1. A method of implanting an endoprosthesis having a plurality of positioning arches, a plurality of retaining arches, and a prosthetic valve attached to the plurality of retaining arches such that at least a part of the prosthetic valve extends from the plurality of retaining arches transversely across an interior of the endoprosthesis, the method comprising:
- positioning the endoprosthesis adjacent a native valve;
expanding the plurality of positioning arches from a collapsed configuration to an expanded configuration while holding the plurality of retaining arches in a collapsed configuration;
positioning the expanded plurality of positioning arches radially outward of at least one native leaflet of the native valve and radially inward of a vessel wall;
expanding the plurality of retaining arches from the collapsed configuration to an expanded configuration; and
engaging the at least one native leaflet of the native valve with at least one of the plurality of positioning arches and at least one of the plurality of retaining arches.

Abstract
A medical device for treating a heart valve insufficiency, with an endoprosthesis which can be introduced into a patient'"'"'s body and expanded to secure a heart valve prosthesis in the patient'"'"'s aorta. In an embodiment, the endoprosthesis has at plurality of positioning arches configured to be positioned with respect to a patient'"'"'s aorta and a plurality of retaining arches to support a heart valve prosthesis. The endoprosthesis includes a first collapsed mode during the process of introducing it into the patient'"'"'s body and a second expanded mode when it is implanted.

18. A method of implanting an endoprosthesis adjacent a native valve having a plurality of native valve leaflets, the endoprosthesis including a plurality of first arches, each first arch having a closed proximal end and an open distal end, a plurality of second arches, and a prosthetic valve attached directly to the plurality of second arches, the method comprising:
-
expanding the plurality of first arches from a collapsed configuration to an expanded configuration while holding the plurality of second arches in a collapsed configuration; positioning a closed end of each of the plurality of first arches within a respective pocket of the native valve before positioning a remainder of each of the plurality of first arches relative to the respective pocket of the native valve; and expanding the plurality of second arches from the collapsed configuration to an expanded configuration after positioning the plurality of first arches within the respective pockets of the native valve. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of implanting an endoprosthesis having a plurality of first arches, each first arch having an open distal end and a closed proximal end, a plurality of second arches, and a prosthetic valve sutured to the plurality of second arches and extending transversely across an interior of the endoprosthesis, the method comprising:
-
maneuvering the endoprosthesis in a collapsed configuration to a position adjacent a native valve, the native valve including a plurality of native valve leaflets; radially expanding the plurality of first arches from a collapsed configuration to an expanded configuration, while holding the plurality of second arches in a collapsed configuration; maneuvering the endoprosthesis with the plurality of first arches expanded relative to the native valve to position the closed proximal end of each of the plurality of first arches within a respective pocket of the native valve such that the respective open ends of the plurality of first arches project away from the respective pocket; radially expanding the plurality of second arches from a collapsed configuration to an expanded configuration to engage at least a portion of the native valve leaflets on a radially inward side with the plurality of second arches. - View Dependent Claims (36, 37, 38, 39, 40, 41)
