Abstract
A heart valve prosthesis is provided that includes a first member and a second member. The first member comprises a first central portion to be disposed adjacent to a line of coaptation on a first side of two adjacent heart leaflets and peripheral portions to be placed into direct contact with the two adjacent heart leaflets. The second member is separate from or can be separable from the first member, for example during delivery. The second member has a central portion and peripheral portions configured to be placed into direct contact with a second side of the two adjacent heart leaflets.

A method, comprising:
- advancing a distal body and at least a portion of a proximal body on a delivery catheter into a first heart chamber of a heart by passing the distal body through a heart valve;
- exposing the distal body and at least the portion of the proximal body outside a distal end of the delivery catheter while in the first heart chamber;
- pivoting the distal body about the proximal body while maintaining contact between the proximal body and the distal body;
- separating the proximal body from the distal body;
- withdrawing the proximal body from the first heart chamber to a second heart chamber by passing the proximal body through the heart valve;
- capturing a portion of a leaflet between the proximal body and the distal body;
- and
- securing the proximal body to the distal body to keep the captured leaflets between the proximal body and the distal body.
