Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material having first and second edges surrounding a central portion; a coaption element formed from the strip of material; and a pair of paddles formed from the strip of material and connected to the coaption element. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient.

Abstract: An implantable prosthetic device has a coaptation element and at least one anchor. The coaptation element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaptation element can have a structure that is impervious to blood. The coaptation element can be connected to leaflets of the native valve by the anchor.

Abstract: Embodiments of the present disclosure include an implantable assembly for a native heart valve that includes a prosthetic heart valve and a braided support structure. The prosthetic valve includes a frame and prosthetic leaflets. The braided support structure has an inner braided layer and an outer braided layer. The outer braided layer is disposed over the inner braided layer. The outer braided layer is less porous to blood than the inner braided layer. The braided support structure defines a plurality of arms that are angularly spaced around the prosthetic heart valve such that each arm extends radially outwardly from the prosthetic heart valve. Other embodiments are also described.

Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a coaption element; a pair of paddles connected to the coaption element; a first cover extending from a distal end of the device and covering at least a portion of the paddles; and a second cover extending from a proximal end of the device and covering at least a portion of the coaption element. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient.

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.

Abstract: An implantable prosthetic spacer device can include an inflatable spacer having a plurality of inflatable members and a frame, the frame comprising one or more anchors and one or more clasps. The inflatable spacer can be configured to be disposed between native leaflets of a heart. The implantable prosthetic spacer can be disposed in a symmetrical or an asymmetrical configuration. The inflatable spacers can be inflatable between an uninflated and an inflated configuration.

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.
