  • Publication number: 20200237512
    Abstract: An implantable prosthetic device has a coaption element and at least one anchor. The coaption 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 coaption element can have a structure that is impervious to blood. The coaption element can be connected to leaflets of the native valve by the anchor.

  • Publication number: 20200113693
    Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a coaption element formed from a strip of material; a pair of extension members; a pair of paddles formed from the strip of material and connected to the coaption element; and a cap attached to the paddles. The paddles are movable between an open position and a closed position, are disposed over the extension member, and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. The cap has a retention body for receiving attachment portions of the extension members, a retaining nut, and a retaining bolt for securing the retaining nut.

  • Publication number: 20200113678
    Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material; a coaption element formed from the strip of material; a pair of paddles formed from the strip of material and connected to the coaption element; a cap attached to the paddles; and a pair of extension members connected to the cap and movable between an open position and a closed position. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. In the closed position the extension members are biased in a closing direction.

  • Publication number: 20200113695
    Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material; a coaption element formed from the strip of material; a pair of paddles formed from the strip of material and connected to the coaption element; a cap attached to the paddles; and a pair of extension members connected to the cap and the paddles via attachment portions. The paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient. Movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position. The extension members extend to end portions attached to the strip material. The end portions extend beyond the strip of material.

  • Publication number: 20200038015
    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.

  • Publication number: 20190290428
    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.
