1. A method of treating a native heart valve, the method comprising:
- introducing an endoprosthesis into a patient'"'"'s vasculature through a femoral artery in a proximal direction towards the native heart valve, wherein the endoprosthesis includes a plurality of first arches, each first arch having an apex pointing in the proximal direction;
positioning the plurality of first arches of the endoprosthesis relative to the native heart valve by placing the apex of each first arch within a respective pocket of the native heart valve, each first arch having an open end opposite the apex and joined to an open end of an adjacent first arch; and
positioning a plurality of second arches of the endoprosthesis radially inward of the plurality of first arches, such that the native heart valve is positioned radially inward of at least a portion of the plurality of first arches and radially outward of at least a portion of the plurality of second arches;
wherein the endoprosthesis includes a prosthetic valve attached to the plurality of second arches, and at least part of the prosthetic valve extends from the plurality of second arches transversely across an interior of the endoprosthesis.

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 a 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.

13. A method of treating a native heart valve, the method comprising:
-
positioning an endoprosthesis proximate the native heart valve, the endoprosthesis extending from a proximal end to a distal end; positioning a plurality of first arches of the endoprosthesis relative to the native heart valve by placing an apex of each first arch within a corresponding pocket of the native heart valve on a first side of a plurality of native valve leaflets, wherein the plurality of first arches points in a proximal direction, and the distal end of the endoprosthesis is distal to the plurality of first arches and points in a distal direction opposite the proximal direction, and wherein each first arch has a U-shape and an open end opposite the apex joined to an open end of an adjacent first arch; and positioning a plurality of second arches of the endoprosthesis on a second side of the plurality of native valve leaflets, such that the native heart valve is positioned radially inward of at least a portion of the plurality of first arches and radially outward of at least a portion of the plurality of second arches, the plurality of first arches being connected to the plurality of second arches by connecting webs; wherein a prosthetic valve is attached to the plurality of second arches of the endoprosthesis, such that at least part of the prosthetic valve extends transversely across an interior of the endoprosthesis. - View Dependent Claims (14, 15, 16, 17)

18. A method of treating a native heart valve, the method comprising:
-
positioning an endoprosthesis relative to the native heart valve by advancing a proximal end of the endoprosthesis through an aortic arch towards the native heart valve, the endoprosthesis comprising three first arches and a plurality of second arches, wherein positioning the endoprosthesis includes; placing an apex of each first arch within a corresponding pocket of the native heart valve by moving the proximal end of the endoprosthesis towards the native heart valve, such that the plurality of first arches is radially outward of three native valve leaflets of the native heart valve, each first arch having an open end opposite the apex and joined to an open end of an adjacent first arch; and placing the plurality of second arches radially inward of the three native valve leaflets, the three first arches being coupled to the plurality of second arches by three connecting webs; wherein the endoprosthesis includes a prosthetic valve attached to the plurality of second arches such that at least part of the prosthetic valve extends from the plurality of second arches transversely across an interior of the endoprosthesis. - View Dependent Claims (19, 20)
