    Abstract: Described herein are systems and methods for securing sutures that obviate the need for tying knots. 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. The device can include a handle, an outer shaft coupled to the handle, an inner shaft movable proximally and distally within the outer shaft; a suture holder at the distal end portion of the outer shaft, and an electrical heating element positioned within the outer shaft. Actuation of the device causes the inner shaft and the heating element to move distally relative to the outer shaft and the suture holder, such that the heating element moves into the proximity of the suture holder to fuse together sutures held by the suture holder.

    Abstract: An implantable heart valve device has a main body including a first end portion and a second end portion. The main body is configured to be implanted around a native leaflet of a heart valve such that the first end portion is on an atrial side of the leaflet and the second end portion is on a ventricular side of the leaflet, and such that the main body can coapt with an opposing native leaflet during operation of the heart valve. One of the first or second end portions comprises a coupling assembly, and the other of the first or second end portions comprises a coupling member configured to extend through the native leaflet when the heart valve device is implanted in a heart valve. The coupling assembly is configured to releasably engage the coupling member to permit adjustment of the relative positions of the first and second end portions.

    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: 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 translation: 一种心脏植入系统，其包括心脏植入物，例如瓣膜成形术环，假体心脏瓣膜或在制造时预先组装的带阀的导管，其中装置使用无缝缝合紧固件将植入物固定到心脏瓣膜环。 无缝缝合紧固件可以嵌入在心脏植入物的柔性密封边缘内，或者它们可以邻近密封边缘定位。 无缝缝合紧固件被弹簧偏置，以便在去除限制装置（例如插入缝合线紧固件内的海波管）时夹紧到环形锚固缝合线上。 引导管与缝合线紧固件一起组装，以允许引入通过缝合线紧固件并穿过密封边缘的缝合线圈，以便于捕获预先安装的环形锚定缝合线。
