    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 device and method for deploying self-cinching surgical clips. The device accesses at least two layers of tissue or material from only one side of the tissue or material and punctures through the two layers of tissue or material. The various configurations of clips disclosed herein are made of a superelastic material such as Nitinol, and have a constrained and a relaxed state, and no sharp edges or tips so as to reduce tissue irritation following deployment. The clip is disposed within the housing of the delivery device and held in a constrained state by a tube assembly until deployment wherein the clip assumes its relaxed state, where the ends of the clip are brought into close approximation, thereby securing the layers of tissue or material together.

    IPC: A61F2/24

    Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.

    IPC: A61F2/24

    Abstract: A prosthetic heart valve holder system includes a prosthetic heart valve having a base at an inflow end, a plurality of commissure posts extending from the base toward an outflow end, and valve leaflets secured to the commissure posts to permit flow through the heart valve. A deflector is provided at the outflow end having a central hub and a plurality of arms extending from the central hub secured to and covering the tips of respective commissure posts. A valve support body is secured to the base and a post connects the valve support body to the hub of the deflector. The plurality of arms are sufficiently collapsible such that, in a first position, free ends of the arms are located axially between the hub and the valve support body to prevent suture looping during an implant procedure, and in a second position, the hub is located axially between the free ends of the arms and the valve support body to permit removal of the deflector from the outflow side of the valve, through the valve leaflets, to the inflow side of the valve.

    Abstract: A dynamic, adjustable annuloplasty ring sizer can include an adjustable ring replica, which can be adjusted through a range of sizes corresponding to available prosthetic annuloplasty repair ring sizes. Actuation of an adjustment trigger on a handle portion of the ring sizer can displace tension wires that extend through a malleable shaft and through a plurality of articulating segments that form the ring replica. Displacement of the tension wires causes flexion of the joints between adjacent articulating segments, thereby reducing the overall size of the ring replica. Releasing the tension wires can allow an elastic extension wire to act on the ring replica, enlarging the ring replica to its maximum, at-rest size. In this manner, the appropriate size of annuloplasty ring prosthesis can be determined with a single device, without requiring a plurality of static ring sizers that require individual insertion and placement for the conventional trial-and-error sizing methods.
