First Claim

1. A method of treating a patient with 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 inhibiting the natural separating of the first and second leaflets in systole by forcing the outer edges of the leaflets together and preventing their separation;
the prosthetic valve 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.

20. A prosthetic valve apparatus comprising an expandable valve seating and a one-way valve coupled to the seating for engageable insertion into an aperture through a mitral valve leaflet to provide a route for unidirectional blood through from a left atrium into a left ventricle of a heart in lieu of natural mitral valve.
