摘要： A heart valve assembly includes an annular prosthesis and a plurality of guide shields removably attached around a circumference of the annular prosthesis. A plurality of elongate guide rails extend from the annular prosthesis, which are releasably retained by the guide shields. During use, the annular prosthesis is directed into a biological annulus, e.g., with the guide rails retained by the guide shields, and secured to tissue surrounding the biological annulus using fasteners. The guide rails are released from the guide shields, and a valve prosthesis is advanced over the leaders and through a passage defined by the guide shields towards the annular prosthesis. The guide rails may include retentions elements that secure the valve prosthesis to the annular prosthesis. The guide shields are removed from the annular prosthesis, the guide rails are separated from the annular prosthesis, and are removed from the biological annulus.

摘要： 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.

摘要： 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.

摘要： A percutaneous heart valve assembly includes a gasket member or other first prosthesis and a valve member or other second prosthesis. The first and second prostheses are contractible from an enlarged or relaxed condition into a contracted or delivery condition. The prostheses may be loaded into the same or separate catheters or other delivery devices for delivery through a patient's vasculature to an implantation site, e.g., a biological annulus within a heart. 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.

摘要： 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.

摘要： A heart valve assembly includes an annular prosthesis and a valve prosthesis. 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. A valve prosthesis is then advanced into the sinus cavity, and secured relative to the annular prosthesis. The sewing cuff may enhance a seal between the valve prosthesis and annular prosthesis.
