Method for implanting prosthetic valve
First Claim
Patent Images
1. A method of treating a patient with regurgitation during systole due to a dysfunctional or diseased valve comprising the steps of:
- (A) piercing an aperture through a first leaflet of the valve;
(B) advancing and positioning a collapsed prosthetic valve apparatus comprising a one-way valve mounted on an expandable seating, into the aperture;
(C) expanding the expandable seating and forcing an outer edge of the first leaflet against an outer edge of a second leaflet, thereby preventing the natural separating of the first and second leaflets in systole by forcing the outer edges of the leaflets together and preventing their separation, thereby preventing regurgitation during systole;
the prosthetic valve apparatus providing an alternative passageway for blood flow therethrough, whilst inhibiting back-flow in systole.

Abstract
A method for implanting a prosthetic valve apparatus in a novel location which replaces the function of a native diseased valve. The prosthetic valve apparatus includes a one way valve and an expandable valve seating. anchoring and securing apparatus in a newly created orifice near or at the center of the anterior valve leaflet. The prosthetic valve apparatus also causes the sealing of the native valve and thus results in a solution for paravalvular leakage and regurgitation.
