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.

Abstract: An implantable prosthetic device can include a frame that is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The frame can include a plurality of struts, each strut comprising a first portion and a second portion separated by a deflection point. Each strut can be curved helically with respect to a first, longitudinal axis of the frame. The first portion of each strut can be curved in a first direction with respect to a first line parallel to a second axis that is perpendicular to the first, longitudinal axis of the frame, and the second portion of each strut can be curved in a second direction with respect to a second line parallel to the second axis.

Abstract: Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.

Abstract: An assembly can comprise a radially expandable and compressible annular frame, at least one linear actuator assembly coupled to the frame and at least one locking mechanism coupled to the frame. The linear actuator can be configured to apply a distally directed force and/or a proximally directed force to the frame to radially expand or compress the frame. The locking mechanism can comprise a first sleeve member connected to the frame at a first location, a second sleeve member having internal threads and being connected to the frame at a second location, and a first screw configured to engage the internal threads of the second sleeve member to retain the frame in a radially expanded state.
