1. A method of treating a native heart valve, the method comprising:
- expanding a plurality of first arches from a collapsed configuration to an expanded configuration while holding a plurality of second arches in a collapsed configuration, each first arch being directly connected to an adjacent first arch;
positioning the expanded plurality of first arches radially outward of at least one native leaflet of the native heart valve and radially inward of a vessel wall;
after positioning the expanded plurality of first arches, expanding the plurality of second arches from the collapsed configuration to an expanded configuration, the plurality of second arches being coupled to a prosthetic valve; and
engaging the at least one native leaflet with at least one first arch of the plurality of first arches and at least one second arch of the plurality of second arches;
wherein the prosthetic valve is not attached to the plurality of first 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.

17. A method of treating a native heart valve, the method comprising:
-
expanding a plurality of first arches from a collapsed configuration to an expanded configuration while holding a plurality of second arches and third arches in a collapsed configuration, each second arch and each third arch pointing in a same direction; positioning the expanded plurality of first arches radially outward of at least one native leaflet of the native heart valve and radially inward of a vessel wall; after positioning the expanded plurality of first arches, expanding the plurality of second arches and third arches from the collapsed configuration to an expanded configuration, the plurality of second arches being coupled to a prosthetic valve; and engaging the at least one native leaflet with at least one first arch of the plurality of first arches and at least one second arch of the plurality of second arches; wherein each second arch has an apex axially aligned with an apex of one of the third arches to define a space therebetween. - View Dependent Claims (18, 19, 20)
