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: In one embodiment, a multi-layer suture fastener that includes a generally disc-shaped body defining a plurality of axially spaced-apart layers. Each layer can include an inner axial surface and an outer axial surface. A suture opening can extend from the inner axial surface to the outer axial surface of each layer. The suture openings can have an open configuration and a closed configuration. One or more lines of suture can be passed through the suture openings when in the open configuration. The suture openings can be placed in the closed configuration. In the closed configuration, the one or more lines of suture can be restricted by radial surfaces of the suture opening from sliding through the suture openings in at least one longitudinal direction of the one or more lines of suture.

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: 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 include 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: 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: 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: 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.
