Abstract: A device for suturing an incision in an artery has a handle, a supply of suture stored on spindle housed in the handle, a tube extending from the handle having a lumen through which suture extends, and a curved needle at a distal end of the handle, the curved needle having an opening through which a free end of the suture extends. A method for suturing an incision in an artery includes creating sequential openings in first and second flaps of the incision, with loops of suture extending through openings in one flap, with a free end of suture extending through the second flap being pulled through the loops and secured to another free end of suture extending through the first flap, to close the incision.

Abstract: Described herein are systems and methods for securing sutures that obviate the need for tying knots. Instead of tying two ends of a suture or two sutures together with a knot, two or more suture portions can be fused or cauterized together using heat. A device can be applied to adjacent suture portions that heats the suture portions and causes the suture portions to fuse together, effectively securing the suture portions together without a knot. Such devices can include a shaft, a heating element positioned within the shaft, and a suture holder at the distal end of the shaft. The holder in an open position receives sutures and in a closed position holds the sutures. Actuation of the device causes the heating element to apply heat and fuse together sutures held by the holder. The holder can separate from the fused sutures after the sutures are fused together.

Abstract: Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.

Abstract: Disclosed suture clips include a generally disk-shaped body having an annular outer body, first and second tabs extending radially inwardly from opposing sides of the annular outer body, first and second slots passing through a thickness of the suture clip and separating the annular outer body from lateral sides of the first and second tabs, and the first and second slots include stepped portions configured to align the suture clip on a rail of a clip deployment device. The stepped slots create bracketing surfaces that interface with the rail on which the clips are mounted, such that the bracketing surfaces prevent or limit the freedom of the clips from tilting or shifting relative to the rail. The disclosed clips can also include rounded edges on engagement surfaces of the tabs to minimize particulate formation.

Abstract: Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

Abstract: A device for deploying a suture clip onto a suture can include a proximal handle portion that includes an actuation mechanism. The device can also include an outer shaft defining an inner lumen. A crimping assembly can be at least partially disposed within a distal end of the outer shaft. The crimping assembly can include a plurality of crimping members configured to receive and radially compress a suture clip. The actuating mechanism can be configured to move the plurality of crimping members radially inwardly from a first position, where the crimping members are configured to receive a suture clip, to a second position where the plurality of crimping members are configured to radially compress the suture clip, causing the suture clip to plastically deform and become secured around one or more sutures.

A device can be applied to adjacent suture portions that heats the suture portions and causes the suture portions to fuse together, effectively securing the suture portions together without a knot. The device can include a handle, an outer shaft coupled to the handle, an inner shaft movable proximally and distally within the outer shaft; a suture holder at the distal end portion of the outer shaft, and an electrical heating element positioned within the outer shaft. Actuation of the device causes the inner shaft and the heating element to move distally relative to the outer shaft and the suture holder, such that the heating element moves into the proximity of the suture holder to fuse together sutures held by the suture holder.

Abstract: Suture clip deployment devices for applying suture clips to sutures are described. Some embodiments can include a generally tubular main body and a vacuum port located at the distal end, a hollow inner body longitudinally slidable within the main body and extending from the main body at its distal end, and a suture recess located in the generally tubular main body. At least one suture clip configured to frictionally fit on an outer surface of the inner body is deployed during use. Clip deployment can occur after a vacuum source is applied to the device so as to draw the suture into the device. The suture lines can be retrieved through the suture recess, and the device can be actuated so as to deliver the suture clip off the delivery device and onto the suture, locking the suture in place.
