Abstract

Apparatus and methods are described herein for anchoring a prosthetic heart valve. In some embodiments, an apparatus includes a tether attachment member that includes a base member that defines at least a portion of a tether passageway through which a portion of a tether extending from a prosthetic heart valve can be received therethrough. The base member defines a locking pin channel that intersects the tether passageway. A locking pin is disposable within the locking pin channel and movable between a first position in which the locking pin is at a spaced distance from the tether passageway, and a second position in which the locking pin intersects the tether passageway and can engage the portion of a tether disposed therein to secure the tether to the tether attachment member.

Claims

1. An anchor apparatus for anchoring a prosthetic heart valve within a heart, comprising:

a tether attachment member including a base member having a retaining channel, and a hub having an outer perimeter portion received within the retaining channel so that the hub is rotatably coupled to the base member, the base member and the hub each defining at least a portion of a tether passageway through which a portion of a tether extending from the prosthetic heart valve can be received therethrough, the base member defining a locking pin channel that intersects the tether passageway at a transverse angle and is in fluid communication therewith; and

a locking pin disposed at least partially within the locking pin channel, a bottom portion of the hub defining a curved channel in which a driver portion of the locking pin is received,

wherein an entirety of the hub, including the curved channel, is configured for limited rotation relative to the base member between a first rotational position and a second rotational position such that the hub drives the locking pin linearly within the locking pin channel moving the locking pin from a first position in which the locking pin is at a spaced distance from the tether passageway, and a second position in which the locking pin intersects the tether passageway and engages a portion of a tether disposed therein to secure the tether to the tether attachment member and to anchor the prosthetic heart valve within the heart;

wherein the driver portion of the locking pin is configured to move along the curved channel as the hub rotates between the first rotational position and the second rotational position.

2. The anchor apparatus of claim 1, further comprising:

a pad coupled to the tether attachment member, the pad configured to contact a ventricular wall such that the pad is disposed between the ventricular wall and the tether attachment member.

3. The anchor apparatus of claim 1, further comprising:

a tube member coupled to the base member, the tube member defining a portion of the tether passageway.

4. The anchor apparatus of claim 1, further comprising:

a tube member coupled to the base member, the tube member defining a portion of the tether passageway; and

a cover member disposed over the tube member.

5. The anchor apparatus of claim 1, wherein the base member defines a detent configured to receive therein a protrusion on the hub to limit the rotation of the hub relative to the base member between the first rotational position and the second rotational position.

6. The anchor apparatus of claim 1, wherein the base member includes cutout sections that are configured to engage coupling arms of a delivery device.

7. The anchor apparatus of claim 6, wherein the base member defines side openings within the cutout sections, the side openings being configured to receive coupling pins extending form the coupling arms of the delivery device.
