TRANSCATHETER MITRAL VALVE PROSTHESIS
First Claim
1. A method of anchoring a prosthetic valve in a patient'"'"'s heart, said method comprising:
- providing the prosthetic valve, wherein the prosthetic valve comprises an anchor having an atrial skirt, an annular region, a ventricular skirt, and a plurality of valve leaflets, wherein the ventricular skirt comprises a first trigonal anchoring tab disposed on an anterior portion of the ventricular skirt, wherein the anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring with the heart;
positioning the prosthetic valve in the patient'"'"'s heart;
expanding the atrial skirt radially outward so as to lie over a superior surface of the patient'"'"'s native mitral valve, and anchoring the atrial skirt against a portion of the atrium;
radially expanding the annular region of the anchor to conform with and to engage the native mitral valve annulus;
anchoring the first trigonal anchoring tab against a first fibrous trigon on a first side of an anterior leaflet of the native mitral valve, such that the anterior leaflet and adjacent chordae tendineae are captured between the trigonal anchoring tab and an anterior surface of the anchor; and
radially expanding the ventricular skirt thereby displacing the native mitral valve leaflets radially outward.

Abstract
A prosthetic cardiac valve comprises an anchor having an atrial skirt, an annular region, and a ventricular skirt. The prosthetic valve also has a plurality of prosthetic valve leaflets each having a first end and a free end. The first end is coupled with the anchor and the free end is opposite the first end. The prosthetic cardiac valve has an open configuration in which the free ends of the prosthetic valve leaflets are disposed away from one another to allow antegrade blood flow therepast, and a closed configuration in which the free ends of the prosthetic valve leaflets engage one another and substantially prevent retrograde blood flow therepast. The anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring the prosthetic cardiac valve to a patient'"'"'s heart.

30. A prosthetic cardiac valve, said valve comprising:
-
an anchor having an atrial skirt, an annular region, and a ventricular skirt, wherein the ventricular skirt comprises first and second trigonal anchoring tabs, both tabs disposed on an anterior portion of the ventricular skirt, the first trigonal anchoring tab adapted to be anchored against a first fibrous trigon on a first side of an anterior leaflet of the patient'"'"'s mitral valve, the second trigonal anchoring tab adapted to be anchored against a second fibrous trigon on a second side of the anterior leaflet, and wherein the anterior leaflet and adjacent chordae tendineae are captured between the trigonal anchoring tabs and an anterior surface of the anchor; wherein the anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring the prosthetic cardiac valve to a patient'"'"'s heart; and a plurality of prosthetic valve leaflets, each of the leaflets having a first end and a free end, wherein the first end is coupled with the anchor and the free end is opposite of the first end, wherein the prosthetic cardiac valve has an open configuration in which the free ends of the prosthetic valve leaflets are disposed away from one another to allow antegrade blood flow therepast, and a closed configuration in which the free ends of the prosthetic valve leaflets engage one another and substantially prevent retrograde blood flow therepast. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 72, 73)

61. A delivery system for delivering a prosthetic cardiac valve to a patient'"'"'s heart, said system comprising:
-
an inner guidewire shaft having a lumen extending therethrough, the lumen adapted to slidably receive a guidewire; a hub shaft concentrically disposed over the inner guidewire shaft; a bell shaft slidably and concentrically disposed over the hub shaft; a sheath slidably and concentrically disposed over the bell shaft; and a handle near a proximal end of the delivery system, the handle comprising an actuator mechanism adapted to advance and retract the bell shaft and the sheath. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69, 70, 71)
