Abstract: In a method of installing an expandable stent in a right ventricular outflow tract, a frame of the expandable stent is positioned at a deployed position in the right ventricular outflow tract, the frame including a waist portion, and first and second opposed sealing portions extending from the waist portion. The frame is expanded such that the waist portion expands to a first diameter, the first sealing portion expands to a second diameter larger than the first diameter and into contact with a first portion of an inner surface of the right ventricular outflow tract, and the second sealing portion expands to a third diameter larger than the first diameter and into contact with a second portion of the inner surface of the right ventricular outflow tract, wherein the waist portion is spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.

Abstract: A prosthetic heart valve includes an annular frame that has an inflow end and an outflow end and is radially compressible and expandable between a radially compressed configuration and a radially expanded configuration. The prosthetic heart valve further includes a leaflet structure positioned within the frame and secured thereto, and an outer sealing member mounted outside of the frame and adapted to seal against surrounding tissue when the prosthetic heart valve is implanted within a native heart valve annulus of a patient. The sealing member can include a mesh layer and pile layer comprising a plurality of pile yarns extending outwardly from the mesh layer.

Abstract: An expandable docking station frame includes a waist portion, a sealing portion connected to the waist portion, and a retaining portion connected to the sealing portion. The sealing portion is expandable radially outward of the waist portion to provide a seal against a first location of an inner surface of a circulatory system at a deployed position over a range of sizes of expansion. The retaining portion is expandable radially outward to engage a second location of the inner surface of the circulatory system at the deployed position, to retain the docking station at the deployed position in the circulatory system. When the expandable docking station frame is in an expanded and unconstrained state, the sealing portion and the retaining portion are joined by a concave profile portion radially inward of each of a first outermost diameter of the sealing portion and a second outermost diameter of the retaining portion.

Abstract: Anchoring or docking devices configured to be positioned at a native valve of a human heart and to provide structural support for docking a prosthetic valve therein. The docking devices can have coiled structures that define an inner space in which the prosthetic valve can be held. The docking devices can have enlarged end regions with circular or non-circular shapes, for example, to facilitate implantation of the docking device or to better hold the docking device in position once deployed. The docking devices can be laser-cut tubes with locking wires to assist in better maintaining a shape of the docking device. The docking devices can include various features to promote friction, such as frictional cover layers. Such docking devices can have ends configured to more securely attach the cover layers to cores of the docking devices.

Abstract: Expandable docking stations for docking an expandable valve can include a valve seat, one or more sealing portions, and one or more retaining portions. The valve seat can be unexpandable or substantially unexpandable beyond a deployed size. The one or more sealing portions are connected to the valve seat and extend radially outward of the valve seat. The one or more sealing portions are constructed to expand outward of the valve seat and provide a seal over a range of sizes. The one or more retaining portions are connected to the one or more sealing portions. The one or more retaining portions are configured to retain the docking station at a deployed position.

Abstract: A prosthetic heart valve includes an annular frame that is radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The frame has a plurality of circumferentially extending rows of angled struts, each row of angled struts comprising angled struts arranged in a zig-zag pattern. The prosthetic heart valve further includes a leaflet structure positioned within the frame and secured thereto, and an outer sealing member mounted outside of the frame. The sealing member has an undulating outflow edge portion forming a plurality of triangular projections that are connected to and shaped to correspond to the zig-zag pattern of one of the rows of angled struts. The outer sealing member is sized to fit snugly against the outer surface of the frame when the frame is in the expanded configuration.

Abstract: A docking device for docking a prosthetic valve at a native valve of a heart can include a coil comprising a plurality of turns and having a proximal end and distal end. The docking device can further include a first covering disposed around and covering the coil from the distal end to the proximal end of the coil, and a second covering disposed over the first covering. A distal end and proximal end of the second covering are spaced away from a distal end and proximal end, respectively, of the first covering.
