Abstract: A coaxial multilumen annulus plane catheter, including an outer pigtail catheter enclosing one or two additional lumens, each housing either a slidable shaped wire or a second pigtail catheter shaped to fit into a wide range of annulus diameters and/or depths. In embodiments, the device may include a catheter delivery handle with thumb/finger-actuated sliders that extend or retract the shaped wires and are sized to enable side-to-side or radial motion, imparting a torque to the pre-shaped wires which translates the length of the wires to enable individually controlled rotation or sweep of each wire to accommodate different annulus diameters. The delivery handle includes hemostasis controls and flush ports. In other embodiments, a handle is obviated by direct lumen axial and rotational control at a proximal end.

Abstract: A valve implant includes a valve leaflet prosthesis having a wire frame, a leaflet blade panel attached to the wire frame, and one or more tether struts extending from the wire frame, and a stent having a first end portion and a second end portion along a longitudinal stent axis, and a flexible extended stent strut extending longitudinally from the first end portion, wherein the one or more tether struts of the valve leaflet prosthesis is rotatably coupled to the flexible extended stent strut in a manner such that the one or more tether struts are rotatable about a rotational axis which is parallel to the one or more tether struts and which extends transverse to the longitudinal stent axis. A delivery system for the valve implant and a method of preparing the delivery system are also disclosed.
