Transcatheter mitral valve prosthesis
First Claim
1. 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, wherein the hub shaft comprises a plurality of slots formed into an outer surface of the hub shaft to create a plurality of discrete recessed regions and disposed adjacent a distal end thereof, the slots configured to receive and hold a portion of the prosthetic cardiac valve;
a bell shaft slidably and concentrically disposed over the hub shaft, the bell shaft having a distal section and a proximal section;
a sheath slidably and concentrically disposed over the bell shaft, wherein the distal section has a diameter larger than a diameter of the proximal section and wherein the sheath is disposed over the larger diameter section of the bell shaft during delivery of the prosthetic cardiac valve; 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.

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.
