Abstract: A device for crimping a radially expandable and collapsible prosthetic valve comprises a coiled wire frame having a longitudinal opening extending from a proximal end to a distal end thereof The opening has a first state and a second state, the opening in the first state having a first diameter dimensioned to receive the prosthetic valve in an expanded or partially crimped configuration therein, and the opening in the second state having a second diameter dimensioned to receive the prosthetic valve in a crimped configuration. The coiled wire frame has a first end coupled to a first member and a second end coupled to a second member. The first member is movable relative to the second member to convert the coiled wire frame from the first state to the second state.

Abstract: Reinforcement members for an outer skirt of a prosthetic heart valve are disclosed. As one example, a prosthetic heart valve can include an annular frame and an outer skirt disposed around an outer surface of the frame, the outer skirt including a sealing layer comprising an outflow edge portion secured to the frame and an inflow edge portion secured to the frame and a deformable reinforcement member attached to the sealing layer. The reinforcement member extends circumferentially along the sealing layer and is configured to extend radially outward from the frame such that the sealing layer bulges radially outward and away from the frame when the frame is radially expanded from a radially compressed state to a radially expanded state. The reinforcement member comprises a circumferentially extending row of cells or an undulating shape.

Abstract: An expandable docking station includes an annular valve seat having an end, an annular outer wall comprising struts disposed around the valve seat, and links that connect the end of the annular valve seat to the annular outer wall. Each of the links extends from the struts of the annular outer wall directly toward a longitudinal axis that runs longitudinally through a center of the docking station, and to a corresponding one of a plurality of circumferentially spaced axially extending legs at least partially defining the annular valve seat. The outer wall is configured to conform to an interior shape of a blood vessel, when expanded inside the blood vessel, such that the outer wall can expand in multiple locations to conform to multiple bulges of the blood vessel and can contract in multiple locations to conform to multiple narrowed regions of the blood vessel.

Abstract: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.

Abstract: An assembly can comprise a prosthetic valve comprising a radially expandable and compressible frame and a rotatable screw connected to the frame, where the screw comprises a screw head having an annular bore with internal threads, and where the screw is rotatable to radially expand the frame. The assembly further comprises a delivery apparatus releasably coupled to the screw, the delivery apparatus comprising a first shaft and a first head disposed at an end of the first shaft, the first head comprising external threads configured to engage with the internal threads of the screw head, and a second shaft that is coaxial with and surrounds the first shaft, the second shaft comprising a second head disposed at an end of the second shaft. The second head is configured to releasably engage with an exterior surface of the screw head and rotate the screw.

Abstract: Devices, assemblies, and methods for displacement of leaflets surrounding a prosthetic valve, such as native leaflets or host leaflets of a previously-implanted prosthetic valve, during valve implantation procedures are disclosed herein. As one example, a valve assembly can include a prosthetic valve and a leaflet engagement frame coupled to the frame of the prosthetic valve. The leaflet engagement frame can include a plurality of engagement frame struts defining one or more rungs, and a plurality of spikes that extend in a distal direction from a first rung of struts of the leaflet engagement frame. The distally extending spikes are configured to engage with one or more native or host leaflets positioned outside the valve assembly when the valve assembly is in a partially expanded state, and to distally fold the engaged native or host leaflets when the valve assembly is further expanded.
