  • Publication number: 20230293168
    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.

  • Patent number: 11759200
    Abstract: Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

  • Patent number: 11707271
    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.

  • Patent number: 11464633
    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.

  • Patent number: 11439385
    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.

  • Patent number: 11395650
    Abstract: Described herein are systems and methods for securing sutures that obviate the need for tying knots. Disclosed suture clips can comprise a first part and a second part that are attachable together to secure one or more sutures in a suture engagement region between the first and second parts. The first and second parts can include locking projections and slots at opposing ends of the suture engagement region to align the two parts, contain sutures, and/or secure the clip onto sutures. When the first and second parts are attached together, first engagement features of the first part inter-engage with second engagement features of the second part to grip and secure sutures within suture engagement region. An exemplary delivery device holds a plurality of such suture clips in an elongated shaft portion and deploys the clips successively to sutures via actuation of a handle portion.

  • Patent number: 11382616
    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.

  • Publication number: 20220133477
    Abstract: Disclosed herein are annular prosthetic devices, such as annuloplasty rings, that include suture clips integrated into or mounted within an annular frame. The clips can quickly secure to sutures to obviate the need to tied knots in the sutures during implantation. Embodiments comprise an annular frame having an open central region and a plurality of suture clips spaced angularly apart around the frame. Each of the suture clips can comprise two opposing tabs that extend toward each other such that the suture clip forms a gripping region between ends of the tabs and the gripping region is configured to grip a suture inserted through the suture clip between the two tabs. The annular frame and the plurality of suture clips can be formed from a single piece of flat material with the suture clip tabs being formed by laser cutting the piece of flat material, or the suture clips can be movable along a track formed in the annular frame.

  • Publication number: 20220071619
    Abstract: A multiple-firing clip device includes a hollow shaft defining a lateral opening communicating with an environment and a distal shaft portion between the lateral opening and a distal end opening. A shuttle longitudinally moves on the shaft and comprises a shuttle body defining a lumen surrounding the shaft, a snare, and a snare-extender slide defining a snare track to form a snare travel path in which the snare is disposed from the body and through the track and a portion of the body. The slide moves along a given extent defining a slide distance and a distal end and movement of the slide to the distal end shortens the snare travel path to extend the snare portion through the lateral opening, through the distal shaft portion, and distally out from a distal side of the body longer than the given extent to secure a suture with the snare.

  • Publication number: 20220008066
    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.
