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.

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: 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.

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.
