An anchor assembly is configured to implant a cardiac anchor into a heart wall of a patient to anchor a suture configured to extend from a valve leaflet of the heart as an artificial chordae. The anchor assembly can include an anchor hub defining an open interior and a helical coil extending distally from the anchor hub and having a sharpened tip configured to embed the helical coil into the heart wall upon rotation of the helical coil. A spring can be disposed within the open interior of the anchor hub. Compressing the spring distally can create an open space within the open interior of the anchor hub for a suture extending through the anchor hub to slide freely and releasing compression on the spring can cause the spring to expand in a proximal direction to clamp the suture within the open interior of the anchor hub.

Helical cardiac anchors for minimally invasive heart valve repair

Disclosed herein are minimally invasive systems and methods for intravascularly accessing the heart and performing a transcatheter repair of a heart valve by inserting a suture as an artificial chordae into a heart valve leaflet. In various embodiments, such systems and methods can be employed in other heart valve repair procedures such an edge to edge repair to coapt leaflets by inserting one or more sutures that retain the leaflets in a coapted positioned or inserting a suture to repair a tear in a leaflet, for example.

Device for suture attachment for minimally invasive heart valve repair

Disclosed herein are various embodiments of suture adjustment mechanisms for 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. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.

Suture length adjustment for minimally invasive heart valve repair

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.
