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.

Claims21

Dependent claims

A heart valve prosthesis, comprising:

a first member comprising a central portion to be disposed adjacent to a line of coaptation on a first side of two adjacent heart leaflets, a first peripheral portion, and a second peripheral portion disposed on an opposite side of the central portion from the first peripheral portion, the first peripheral portion and the second peripheral portion configured to be placed into direct contact with the two adjacent heart leaflets;
and
a second member separate from the first member, the second member comprising a central portion, a first peripheral portion, and a second peripheral portion disposed on an opposite side of the central portion of the second member from the first peripheral portion, the first peripheral portion and the second peripheral portion of the second member configured to be placed into direct contact with a second side of the two adjacent heart leaflets;
wherein in a delivery state the first and second members are in a first aligned delivery configuration in which the second peripheral portion of the first member is disposed over the first peripheral portion of the second member and the first peripheral portion of the first member is disposed distal to the first peripheral portion of the second member;
and
wherein the first and second members transition to a second aligned deployed configuration in which the first peripheral portion of the first member is disposed over the first peripheral portion of the second member and the second peripheral portion of the first member is disposed over the second peripheral portion of the second member.

A heart valve prosthesis, comprising:

a first member comprising 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;
a second member separate from the first member, the second member comprising a central portion and peripheral portions configured to be placed into direct contact with a second side of the two adjacent heart leaflets;
wherein the first member comprises a first hinge portion having a concave surface disposed in the first central portion and a concave recess disposed in one of the peripheral portions, and wherein one of the peripheral portions of the second member comprises a second hinge portion having a convex surface;
and
wherein the first and second hinge portions are in contact in a delivery configuration and at least a portion of the convex surface of the second member is in contact with the concave surface of the first member to control movement of the first member relative to the second member about the second hinge portion, the first and second hinge portions disengageable to provide a deployed configuration for trapping one or more leaflets, the convex surface of the second member being aligned with and/or received in the concave recess of the first member in the deployed configuration for trapping.
