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 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 then move distally to prepare to deploy the next suture clip.

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 suture clips comprise 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 comprise 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 comprise rounded edges on engagement surfaces of the tabs to minimize particulate formation.

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.

Abstract: Described herein are reusable surgical needles having a resiliently collapsible rear loop that captures a suture as it is passed through an object and resiliently expands upon exiting the object to release the suture. Also described are suture spool assemblies that comprise a rigid housing and a rotatable spool of suture material suspended within the housing so that a plurality of sutures can be dispensed from the assembly in succession during a surgery. Also described are annular pledgets having diametrical dimensions similar to an outer ring of a cardiac implant such that a single annular pledget can be used with a plurality of sutures that secure the cardiac implant to native tissue around the perimeter of the cardiac implant. Related methods of suturing cardiac implants are also disclosed.

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: A cardiac implant system including a cardiac implant such as an annuloplasty ring, a prosthetic heart valve, or a valved conduit pre-assembled at the time of manufacture with devices for securing the implant to a heart valve annulus using knotless suture fasteners. The knotless suture fasteners may be embedded within a pliant sealing edge of the cardiac implant, or they may be positioned adjacent to the sealing edge. The knotless suture fasteners are spring-biased so as to grip onto annulus anchoring sutures pass to therethrough upon removal of a restraining device, such as a hypotube inserted within the suture fasteners. Guide tubes are assembled in line with the suture fasteners to permit introduction of suture snares that pass through the suture fasteners and through the sealing edge to facilitate capture of the pre-installed annulus anchoring sutures.
