  • Publication number: 20220061991
    Abstract: 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.

  • Publication number: 20220000470
    Abstract: A knotless suture anchor system is disclosed for improved anchoring in tissue. The knotless suture anchor system includes an anchor body having an exterior surface, a proximal end, a distal end, a longitudinal axis extending between the proximal and distal ends, an interior longitudinal passageway extending at least partway from the proximal end toward the distal end, a proximal opening communicating with the longitudinal passageway nearer the proximal end, and a distal opening communicating with the longitudinal passageway nearer the distal end. The knotless suture anchor system also includes an interference member insertable distally into the longitudinal passageway to secure a portion of a suture within the longitudinal passageway by compressing the portion of the suture between the interference member and the anchor body, and a frangible connection that joins a proximal member to the anchor body.

  • Publication number: 20210282764
    Abstract: 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.

  • Publication number: 20200281582
    Abstract: In one embodiment, a suture attachment catheter configured to repair a heart valve by inserting a suture in a valve leaflet of a beating heart of a patient includes a handle control, a flexible catheter body, and a suture attachment assembly at a distal end of the catheter body. The suture attachment assembly can include a rail between a distal clamping jaw hingedly attached to the rail, and a proximal clamping jaw. One of the proximal clamping jaw or distal clamping jaw can be selectively slideable with respect to the other on the rail using a jaw actuator of the control handle to adjust a distance between the proximal clamping jaw and the distal clamping jaw. A needle can be selectively slideable within the catheter body by using a needle actuator of the proximal handle control to penetrate a valve leaflet and insert a suture through the valve leaflet when the valve leaflet is captured between the proximal clamping jaw and the distal clamping jaw.

  • Patent number: 10667927
    Abstract: An expandable fusion cage system includes an expandable fusion cage having an upper portion, a lower portion, and a hinge portion coupling the lower portion and the upper portion at their distal ends. Positioned between the upper and lower portions is an expansion element that when moved in the proximal direction causes the cage to expand at its proximal end. The system can also include inserter instruments, expandable distraction instruments, and bone funnels.

  • Publication number: 20190343634
    Abstract: Disclosed herein are various embodiments of 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. Each of the disclosed anchor embodiments transitions from a first position for delivery of the anchor to the heart wall to a second position for insertion of the anchor into the heart wall. In some embodiments, it is the transition to the second position that provides the necessary 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.
