Patent number: 11957584Abstract: 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.Type: GrantFiled: November 11, 2021Date of Patent: April 16, 2024Assignee: NEOCHORD, INC.Inventors: Graham Garvin, Joel Helgerson, Tim Crowley, Tom Broome, Daryl Edmiston

Publication number: 20230270432Abstract: 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.Type: ApplicationFiled: March 20, 2023Publication date: August 31, 2023Inventors: Levi Caffes, Joel Helgerson, Andrew Schifle, Daryl Edmiston

Publication number: 20220000470Abstract: 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.Type: ApplicationFiled: August 31, 2021Publication date: January 6, 2022Applicant: CROSSROADS EXTREMITY SYSTEMS, LLCInventors: T.

Publication number: 20190343634Abstract: 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.Type: ApplicationFiled: May 8, 2019Publication date: November 14, 2019Inventors: Graham Garvin, Tim Crowley, Joel Helgerson, Tom Broome, Daryl Edmiston
