Cardiac implant with integrated suture fasteners
First Claim
1. A knotless heart valve system, comprising:
- a prosthetic heart valve having an inner frame arranged around a flow axis through the heart valve along which blood will flow from an inflow side to an outflow side thereof when implanted, and occluding members that provide one-way flow through the valve and mounted to move within the inner frame; and
a plurality of knotless suture fasteners distributed around an outer periphery of the inner frame and attached to the heart valve, each fastener having an axial slot sized to receive a suture and facing radially outward such that a suture may be passed laterally 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, the heart valve being capable of being anchored to a native annulus without the use of knots by passing sutures pre-installed at the annulus into each fastener and converting the fasteners to their closed states.

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.

11. A knotless annuloplasty ring system, comprising:
-
an annuloplasty ring having a metallic core and a pliant sealing edge surrounding the core, the annuloplasty ring being arranged around a flow axis along which blood will flow from an inflow side to an outflow side of the annuloplasty ring when implanted, the pliant sealing edge having inflow and outflow faces; and a plurality of knotless suture fasteners distributed around the sealing edge and attached thereto, each fastener having an axial slot sized to receive a suture and facing radially outward such that a suture may be passed laterally 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, the annuloplasty ring being capable of being anchored to a native annulus without the use of knots by passing sutures pre-installed at the annulus into each fastener and converting the fasteners to their closed states. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
