Mitral valve prosthesis
First Claim
1. A method of treating a defective mitral valve, comprising:
- inserting a delivery catheter through a small incision in a patient'"'"'s groin, the delivery catheter having a prosthetic device contained within a sheath along a distal end of the delivery catheter, the prosthetic device comprising an insert member and anchoring member;
advancing the distal end of the delivery catheter through a patient'"'"'s vasculature and into a left ventricle;
securing the anchoring member to a muscular wall of the left ventricle; and
allowing the insert member to self-expand between native leaflets of a mitral valve, the insert member including a biocompatible fabric outer layer, a passageway extending therethrough along a longitudinal axis extending from a left atrium to the left ventricle, and a valve member disposed within the passageway, the valve member including one or more flap members defining a one-way valve;
wherein, after deployment of the prosthetic device, the native leaflets of the mitral valve form a tight seal against the fabric outer layer of the insert member for preventing regurgitation, while blood passes through the passageway of the insert member for allowing blood to pass from the left atrium to the left ventricle.

Abstract
A method of treating a defective mitral valve includes percutaneously advancing a prosthetic device into a patient'"'"'s heart. The prosthetic device includes an insert member and anchoring member. The prosthetic device is contained within a sheath along a distal end of a delivery catheter during advancement. The anchoring member is secured to a muscular wall of the left ventricle and the insert member self-expands between native leaflets of the mitral valve. The insert member preferably includes a biocompatible fabric outer layer, a passageway, and a valve member disposed within the passageway. After deployment, the native leaflets of the mitral valve form a tight seal against the fabric outer layer of the insert member for preventing regurgitation, while blood passes through the passageway of the insert member for allowing blood to pass from the left atrium to the left ventricle.

17. A method of treating a defective mitral valve, comprising:
-
inserting a delivery catheter through a small incision in a patient'"'"'s groin, the delivery catheter having a prosthetic device contained within a sheath along a distal end of the delivery catheter, the prosthetic device comprising an insert member and anchoring member formed with a plurality of elongated prongs; advancing the distal end of the delivery catheter through a patient'"'"'s vasculature and into a left ventricle; allowing the elongated prongs to self-expand within a muscular wall of the left ventricle for securing the anchoring member to the left ventricle; and allowing the insert member to self-expand between native leaflets of a mitral valve, the insert member including a biocompatible fabric outer layer, a passageway extending therethrough along a longitudinal axis extending from a left atrium to the left ventricle, and a valve member disposed within the passageway, the valve member including one or more flap members defining a one-way valve; wherein, after deployment of the prosthetic device, the native leaflets of the mitral valve form a tight seal against the fabric outer layer of the insert member for preventing regurgitation, while blood passes through the passageway of the insert member for allowing blood to pass from the left atrium to the left ventricle. - View Dependent Claims (18, 19, 20)
