Abstract
Disclosed herein are various embodiments of cardiac anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Such cardiac anchors are particularly suitable for use in intravascular, transcatheter procedures.
Claims23
A cardiac anchor configured to be implanted into a heart wall of a heart of a patient to anchor a suture configured to extend from a valve leaflet of the heart as an artificial chordae, the anchor comprising:
- an anchor body including an actuation head at a proximal end of the anchor body configured to be engaged by an actuation tool to enact rotation of the anchor body;
- a coil extending around at least a portion of the anchor body and distally of the anchor body, the coil having a distal tip configured to be transversely driven into and along the heart wall;
- a flexible shaft extending from the anchor body distally through a longitudinal axis of the coil such that the flexible shaft extends distally beyond the coil;
- and
- a blunt tip at a distal end of the flexible shaft, wherein the blunt tip and flexible shaft are configured such that the flexible shaft bends against the heart wall when the blunt tip is forced against the heart wall to stabilize a position of the coil with the longitudinal axis of the coil in a position generally parallel relative to the heart wall.
A cardiac anchor configured to be implanted into a heart wall of a heart of a patient to anchor a suture configured to extend from a valve leaflet of the heart as an artificial chordae, the anchor comprising:
- an anchor body including an actuation head at a proximal end of the anchor body configured to be engaged by an actuation tool to enact rotation of the anchor body;
- a coil extending around at least a portion of the anchor body and distally of the anchor body, the coil having a distal tip configured to be transversely driven into and along the heart wall;
- and
- means for orienting the coil transversely to the heart wall such that rotation of the coil causes the coil to become embedded transversely along the heart wall, wherein the means for orienting the coil bends against the heart wall to stabilize a position of the coil with the longitudinal axis of the coil in a position generally parallel relative to the heart wall.

- a flexible shaft extending from the anchor body distally through the coil such that the flexible shaft extends distally beyond the coil;
- and
- a blunt tip at a distal end of the flexible shaft, wherein the coil defines a series of coil turns configured such that only a portion of each coil turn is embedded in the heart wall, the flexible shaft is configured to bend against the heart wall when the blunt tip is forced against the heart wall to stabilize a position of the coil with the longitudinal axis of the coil in a position generally parallel relative to the heart wall.
