摘要:
Apparatus and methods are described herein for various embodiments of a prosthetic heart valve that have a tether securement feature that can be used to secure an anchoring tether to the prosthetic heart valve such that the tether can maintain the prosthetic heart valve in a desired position within the heart under high tensile forces applied to the tether during functioning of the heart. In some embodiments the tether securement feature can also include an engagement member that can be used to help position the prosthetic heart valve within a heart. Such an engagement member can be matingly engaged by a positioning device that can be used to help in radial positioning of the prosthetic heart valve during delivery and deployment of the prosthetic heart valve.
