METHODS FOR RETAINING A PROSTHETIC HEART VALVE
First Claim
1. A method of retaining a prosthetic heart valve at a native aortic valve having three aortic valve leaflets and three intermediate commissures, comprising:
- delivering a support member to an outflow side of a native aortic valve of a patient, the support member comprising an annular body sized such that it can be positioned within the aorta of a patient and around the native aortic valve leaflets, the support member defining three peaks and three valleys;
orienting the support member so that the three peaks are adjacent to the commissures and the valleys are adjacent to the leaflets of the aortic valve;
after positioning the support member around the leaflets of the aortic valve, delivering an expandable prosthetic heart valve to within the aortic valve leaflets; and
expanding the expandable prosthetic heart valve into contact with the leaflets of the aortic valve, thereby causing the leaflets to be secured between an inner surface of the support member and an outer surface of the prosthetic heart valve.

Abstract
A prosthetic valve system for replacing a native aortic valve exhibiting regurgitation comprises a support structure and a transcatheter heart valve (THV) that is separate from the support structure. The support structure is radially collapsible and expandable, and deployable on an outflow side of the native aortic valve, circumscribing the native leaflets of the aortic valve. The THV is radially collapsible and expandable, and deployable in an annulus of the native aortic valve to frictionally engage the native leaflets between an interior surface of the support structure and the THV.

11. A method of retaining a prosthetic heart valve at a native valve having leaflets, comprising:
-
delivering a support member to an outflow side of a native valve of a patient, the support member comprising an annular body sized such that it can be positioned around the native valve leaflets; after positioning the support member around the native valve leaflets, delivering an expandable prosthetic heart valve to within the valve leaflets; and expanding the expandable prosthetic heart valve into contact with the native valve leaflets, thereby causing the leaflets to be pinched between an inner surface of the support member and an outer surface of the prosthetic heart valve. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
