Abstract
Various embodiments of anchors are 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. Each of the disclosed anchor embodiments 'toggles' from a first position for delivery of the anchor to the heart wall and a second position for insertion of the anchor into the heart wall. In some embodiments, it is the 'toggle' to the second position that provides the insertion force for inserting the anchor into the heart muscle sufficient to retain the anchor from accidental withdrawal from the heart wall during normal valve operation (e.g., when a valve leaflet pulls on the suture attached to the anchor during systole). Such anchors are particularly suitable for use in intravascular, transcatheter procedures as described above given the inherent difficulties in providing sufficient force for insertion of an anchor into the heart wall with a flexible catheter.
