Abstract: Systems, assemblies, and methods for treating valve regurgitation and other valve problems are described. Prosthetic valves can have integrated coverings or flanges. Prosthetic valves can have a flange attached to the inflow end of the annular frame and designed to extend outwardly therefrom. Docking devices can be used to repair or reshape native heart valves and to secure prosthetic heart valves at a specific location and position relative to a native heart valve. Delivery systems can be used to deploy a docking device into the heart, including a lubricous sleeve in the delivery system. Packaging and storage systems suitable for the delivery systems are described.

Abstract: A prosthetic heart valve includes a frame having an inflow end and an outflow end, and defining a longitudinal axis. The prosthetic heart valve further includes a leaflet structure situated at least partially within the frame, and a covering disposed around the frame. The covering includes a first woven portion extending circumferentially around the frame and including a plurality of texturized strands or yarns extending along the longitudinal axis of the frame. The covering further includes a second woven portion extending circumferentially around the frame and spaced apart from the first woven portion along the longitudinal axis of the frame. The texturized strands extend along the longitudinal axis of the frame from the first woven portion to the second woven portion and form a floating portion between the first woven portion and the second woven portion.

Abstract: A prosthetic heart valve includes a frame having a plurality of strut members, and having an inflow end and an outflow end. A leaflet structure is situated at least partially within the frame, and a covering is disposed around an exterior of the frame. The covering includes a cushioning layer, a first strip member folded over the inflow end of the frame and sutured to itself through the frame to form a first protective portion, and a second strip member folded over the outflow end of the frame and sutured to itself through the frame to form a second protective portion.

Abstract: Embodiments are provided of an assembly having a prosthetic valve, the prosthetic valve having a radially expandable and compressible annular frame, and a crimping accessory device, and methods for using the assembly in compressing the prosthetic valve. The frame includes an outer surface and an inner surface. A leaflet assembly is supported inside the annular frame. The leaflet assembly includes a plurality of leaflets, each having an inner surface and an outer surface. The crimping accessory device has a plurality of axially-extending fingers. At least a first finger of the plurality of fingers is disposed between the outer surface of a first leaflet of the plurality of leaflets, and at least a second finger of the plurality of fingers is disposed radially-inwardly of the inner surface of the first leaflet.

Abstract: Certain examples of the disclosure concern a guard member for a docking device configured to receive a prosthetic valve. The guard member can include an expandable member and an elastic member extending along an axial length of the expandable member. The expandable member can be movable between a radially compressed state and a radially expanded state. When the expandable member is in the radially compressed state, the elastic member can be in an axially stretched state. The elastic member in the axially stretched state can be configured to return to a resting state, thereby moving the expandable member from the radially compressed state to the radially expanded state.

Abstract: A prosthetic heart valve has a frame including a plurality of strut members, an inflow end, and an outflow end. A leaflet structure is situated at least partially within the frame, and a covering is disposed around an exterior of the frame. The covering includes a cushioning layer, and a first strip member folded over an inflow circumferential edge portion of the cushioning layer to form a first protective portion. A second strip member is folded over an outflow circumferential edge portion of the cushioning layer to form a second protective portion. The first strip member and the second strip member are spaced apart from each other along a longitudinal axis of the prosthetic heart valve.
