    • A fastener delivery tool includes a loading chamber for receiving a fastener having a pair of tines overlapping one another to define a loop in a parent or relaxed state. A retaining member retains the fastener in the loading chamber. The fastener delivery tool also includes a tongue, pusher member, and an ejection track communicating with the loading chamber. An actuator causes the tongue to move to engage the tines of the fastener to transform the fastener from the relaxed state to a constrained state defining a U-shape. The actuator also causes the pusher member to release the retaining member and advance the fastener down the ejection track in the constrained state. The tool also includes a trigger for ejecting the fastener completely from the ejection track. The fastener may be used to secure a prosthetic heart valve or components thereof into surrounding tissue, e.g., within a tissue annulus.
    • 紧固件输送工具包括用于接纳紧固件的装载室,所述紧固件具有一对彼此重叠的齿,以限定处于母体或松弛状态的环。 保持构件将紧固件保持在装载室中。 紧固件输送工具还包括舌头,推动器构件和与装载室连通的排出轨道。 致动器使舌头移动以接合紧固件的尖齿,以将紧固件从松弛状态转变为限定U形的约束状态。 致动器还使得推动器构件释放保持构件并且在紧固状态下将紧固件向下推出排出轨道。 该工具还包括用于从弹出轨道完全弹出紧固件的触发器。 紧固件可以用于将假体心脏瓣膜或其部件固定到周围组织中,例如在组织环空中。

    • A valve introducer is provided for delivering a valve prosthesis into a biological annulus. During use, a gasket member is introduced into the biological annulus, and secured relative to the biological annulus. A distal end of a valve introducer is introduced into a passage communicating with the biological annulus, and disposed adjacent the gasket member. A valve prosthesis is advanced through the valve introducer towards the gasket member, and secured to the gasket member. In one embodiment, the valve introducer and valve prosthesis have corresponding shapes, requiring the valve prosthesis to be oriented to properly align the valve prosthesis before advancing the valve prosthesis into the valve introducer. Optionally, the valve introducer is compressed or otherwise manipulated to reduce a profile of the distal end before introduction into the passage, which may facilitate introducing the valve introducer through the passage, e.g., past the sino-tubular junction.
    • 提供了一种阀导管器,用于将瓣膜假体递送到生物环空中。 在使用期间,垫圈构件被引入到生物环空中,并相对于生物环固定。 阀导入器的远端被引入到与生物环带连通的通道中,并且邻近垫圈构件设置。 阀门假体通过阀导入器前进到垫圈构件,并固定到垫圈构件。 在一个实施例中,阀导入器和瓣膜假体具有相应的形状,需要在将瓣膜假体推入瓣膜引导器之前将瓣膜假体定向成适当对准瓣膜假体。 可选地,阀导入器被压缩或以其他方式操纵以在引入通道之前减小远端的轮廓,这可以有助于引导阀导入器穿过通道,例如通过中肠管结。

The first prosthesis may be deployed adjacent or within the biological annulus and secured at least partially into the biological annulus. The second prosthesis may then be deployed adjacent the biological annulus, expanded, and docked to the first prosthesis. In one embodiment, the first and/or second prostheses may be advanced over one or more sutures or other filaments secured to tissue surrounding or adjacent the biological annulus.

    • A heart valve assembly includes a prosthesis for receiving a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus adjacent a sinus cavity. The prosthesis includes an annular member implantable within the biological annulus for contacting tissue surrounding the biological annulus to provide an opening through the biological annulus, a collar extending upwardly from the annular member, and a sewing cuff extending radially outwardly from the annular member and/or collar. Optionally, the annular member and/or collar may be resiliently compressible, expandable, and/or otherwise biased. A valve member, e.g., a mechanical or bioprosthetic valve may be coupled to the collar, e.g., using a drawstring, sutures, or other connectors, to secure the valve member to the gasket member.

The annular prosthesis includes an annular ring for dilating tissue within a biological annulus and a conformable sewing cuff extending radially from the annular member. The valve prosthesis includes a frame and a valve component. The annular ring is introduced into the biological annulus to dilate tissue surrounding the biological annulus and the sewing cuff conforms to tissue above the biological annulus. Fasteners are directed through the sewing cuff to secure the annular prosthesis to the biological annulus. The annular prosthesis may include a baleen element for biasing fabric on the annular ring outwardly to enhance sealing against the biological annulus.
