CARDIAC IMPLANT WITH INTEGRATED SUTURE FASTENERS
First Claim
1. A cardiac implant system, comprising:
- a cardiac implant having an inner frame arranged around a flow axis through the implant along which blood will flow when implanted from an inflow side to an outflow side of the implant, and a pliant sealing edge extending outward from the inner frame and having inflow and outflow faces, the sealing edge having formed therein a plurality of generally axial slits that open radially outward; and
a plurality of knotless suture fasteners distributed around and at least partially embedded into the sealing edge and secured therein, each fastener having an axial slot sized to receive a suture and facing radially outward, and each fastener being located adjacent one of the axial slits in the sealing edge such that a suture may be passed through the slit and into the axial slot of the fastener, each fastener having an open state which permits a suture to slide axially therethrough and a closed state which prevents axial movement of the suture in at least one direction.

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.
