First Claim
1. A method of deploying a prosthesis within a native mitral valve, the method comprising:
- delivering an expandable frame configured to radially expand and collapse between an expanded configuration and a collapsed configuration to the native mitral valve in the collapsed configuration, the expandable frame comprising;
a proximal end having a number of proximal anchors, the number of proximal anchors each connected to the frame and having a free end positioned radially outward from the frame when the frame is in the expanded configuration, wherein each of the number of proximal anchors comprises first and second struts connected to and extending radially outward from the frame when the frame is in the expanded configuration, the first and second struts each comprising a substantially straight segment;
a distal end having a number of distal anchors, the number of distal anchors equal to the number of proximal anchors, the number of distal anchors each having a free end positioned radially outward from the frame and extending toward the proximal end when the frame is in the expanded configuration, wherein each of the number of proximal anchors has a different shape from a shape of each of the number of distal anchors; and
a valve body attached to the expandable frame, wherein the valve body can move between (i) an open position wherein blood can flow from the proximal end toward the distal end; and
(ii) a closed position which blocks blood from flowing from the distal end toward the proximal end; and
radially expanding the expandable frame to the expanded configuration, wherein the radially expanding causes the free ends of the number of proximal anchors and the number of distal anchors to draw closer together;
wherein, in the expanded configuration, the number of proximal anchors are on an inflow side of the native mitral valve and the number of distal anchors are on an outflow side of the native mitral valve.

Abstract
A method of deploying a prosthesis within a native mitral valve is disclosed. The expandable frame preferably includes about twelve proximal anchors, wherein the proximal anchors have free ends positioned radially outwardly from the frame in an expanded configuration. The expandable frame preferably includes about twelve distal anchors, wherein the distal anchors also have a free ends positioned radially outwardly from the frame and extend toward a proximal end when the frame is in the expanded configuration. A valve body is supported within the frame for preventing blood flow in one direction. The expandable frame is radially expanded during deployment, which causes the free ends of the proximal and distal anchors to move closer together. In the expanded configuration, the proximal anchors are positioned on an inflow side of the native mitral valve and the distal anchors are positioned on an outflow side of the native mitral valve.
