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 has hold a plurality of such suture clips in an elongated shaft portion and deploy the clips successively to sutures via actuation of a handle portion.

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.

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.

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 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.

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: 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.
