Abstract
A mitral valve prosthesis includes an expandable frame having a proximal end, a distal end, and a middle portion. A plurality of tips extend from the proximal end of the frame for attachment to a delivery catheter. A plurality of anchors are disposed along the distal end of the frame and extend toward the proximal end for engaging tissue. An outer circumferential portion extends around the middle portion of the frame and is positioned radially outwardly of the frame. The outer circumferential portion preferably increases in diameter along a distal direction. A distal end of the outer circumferential portion is located distal of free ends of the anchors when the expandable frame is deployed. A valve body is positioned within an interior of the expandable frame and includes leaflets adapted to allow flow in a first direction and prevent flow in a second direction.
