Abstract
An apparatus for treating a mitral valve, comprising an elongate member having a spiral shape, the elongate member having a proximal end portion and a distal end portion, an expandable proximal anchor joined to the proximal end portion of the elongate body, and an expandable distal anchor joined to the distal end portion of the elongate body. The elongate member is configured to adjust from an elongated state to a shortened state after delivery at least partially into a coronary sinus for reshaping a mitral annulus.
Claims20
An apparatus for treating a mitral valve, comprising:
- an elongate member formed with a substantially spiral shape, the elongate member having a proximal end portion and a distal end portion;
- an expandable proximal anchor joined to the proximal end portion of the elongate member;
- and
- an expandable distal anchor joined to the distal end portion of the elongate member;
- wherein the elongate member is configured to adjust from an elongated state to a shortened state after delivery at least partially into a coronary sinus for reshaping a mitral annulus.
An apparatus for treating a mitral valve, comprising:
- an elongate member having a spiral shape, the elongate member having a proximal end portion and a distal end portion, wherein the elongate member comprises a plurality of coils;
- an expandable proximal anchor joined to the proximal end portion of the elongate body;
- and
- an expandable distal anchor joined to the distal end portion of the elongate body.
A method for treating a mitral valve using an implant, the implant including an elongate member having a spiral shape with coils, the elongate member having a proximal end portion and a distal end portion, an expandable proximal anchor joined to the proximal end portion of the elongate member, and an expandable distal anchor joined to the distal end portion of the elongate member, the method comprising:
- inserting the implant at least partially into the coronary sinus;
- expanding and anchoring the expandable distal anchor in the coronary sinus;
- expanding and anchoring the expandable proximal anchor in or outside of the coronary sinus.
