Abstract: A knotless suture fastener installation system for securing medical devices such as cardiac implants. The knotless suture fasteners may be spring-biased so as to grip onto sutures passed therethrough. The system includes a fastener deployment tool with a proximal handle and a distal shaft to which a fastener cartridge attaches. A plurality of disposable cartridges are sequentially attached to the end of the deployment tool and used to secure the medical implant one fastener at a time. The deployment tool may also cut the sutures being fastened.

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 surgical site retractor is configured to retract tissue, such as in an intercostal procedure. The retractor may be formed from non-radiopaque material for improved monitoring via X-ray imaging. The retractor may have a rigid retractor and a soft tissue retractor, where the rigid retractor has a plurality of legs and the soft tissue retractor extends between the legs to prevent soft tissue from extending between said legs. The retractor may have a bendable arm with an implement holder, such as distal cuff or clip adapted to resiliently hold an implement such as a tube of an elongated port-access device. A method involves partly installing the surgical site retractor, expanding the surgical site retractor, deploying the surgical implement from outside the body through the incision and into the patient, resiliently capturing the implement with the holder of the arm, and bending the arm to hold the implement in a desired position.

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.

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: Described herein are systems and methods for securing sutures that obviate the need for tying knots. 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.
