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: 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: 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: A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.

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.
