Minimally invasive heart valve repair in a beating heart
11589989 · 2023-02-28 · ·

In one embodiment, a method of repairing a heart valve accesses an interior of a patient's beating heart minimally invasively and inserts one or more sutures into each of a plurality of heart valve leaflets with a suturing instrument. The suture ends of the sutures are divided into suture pairs, with each pair including one suture end from a suture inserted into a first valve leaflet and one suture end from a suture inserted into a second valve leaflet. One or more tourniquet tubes is advanced over the suture pairs to the leaflets to draw the sutures together to coapt the leaflets and then the sutures are secured in that position.

Implant devices with a pre-set pulley system
11589870 · 2023-02-28 · ·

The problem of positioning one or more nerve ends inside a sheathing implant is solved by the use of a pulley and cinching systems that pull a nerve end into an implant and that can adjust the diameter of an implant to conform the implant to the diameter of the nerve, respectively. The pulley system utilizes a suture that traverses the wall of an implant leaving one end outside the implant wall and another end that can be attached to a nerve. Pulling the suture end outside the wall pulls the nerve attached to the other end of the suture into the bore of the implant. A cinching system utilizes specially arranged sutures within the wall of an implant to tighten or cinch up the wall after a nerve is placed therein, so as to conform at least part of the implant to the diameter of the nerve. Methods are also disclosed by which such pulley systems can be formed during an intraoperative procedure.

Systems, devices, and methods for securing tissue
11564676 · 2023-01-31 · ·

Systems, devices, and methods are provided for securing soft tissue to bone, for securing one or more objects using a surgical filament, and for drawing two or more tissues together so they can be secured in a desired location. One exemplary embodiment of a surgical repair construct that is configured to atraumatically pass through soft tissue to secure tissue in a knotless manner includes a snare linkage, a collapsible loop, and a flexible suture pin. The snare linkage can include a collapsible snare for receiving the collapsible loop, and in use the snare can be collapsed around the collapsible loop and advanced distally towards the bone until the snare is proximate to the tissue, while the collapsible loop can be collapsed distally towards the bone to bring the tissue into proximity with the bone. Other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

Device and method for intracorporeal and extracorporeal laparoscopic suturing and knot tying

An apparatus for laparoscopic intracorporeal knot tying includes a needle grasper including a needle holder shaft and a needle holder jaw located at a distal end of the needle holder shaft, and a knot loop grasper including a knot loop holder shaft, which is slidable on the needle holder shaft, and a knot loop holder jaw located at a distal end of the knot loop holder shaft. In an inactive state of the apparatus, the knot loop holder is located proximal to the needle holder jaw. In an active state of the apparatus at a time of a knot tying, the knot loop holder jaw slides on the needle holder shaft toward the distal end of the needle holder shaft and beyond the needle holder jaw to carry components of a knot over a standing end of a suture held by the needle holder jaw.
