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.

Systems, devices, and methods for treating heart valves

A prosthetic heart valve has a frame including a plurality of strut members, the frame being radially expandable and collapsible between a collapsed state and an expanded state, the frame having an inflow end and an outflow end and defining a longitudinal axis. A leaflet structure is situated at least partially within the frame. A covering is disposed around an exterior of the frame and includes a cushioning layer, a first strip of material coupled to the cushioning layer and folded to encapsulate apices of the strut members of the inflow end of the frame, and a second strip of material coupled to the cushioning layer and folded to encapsulate apices of the strut members of the outflow end of the frame. The cushioning layer includes texturized filaments that provide compressible volume and a plush surface to the cushioning layer when the frame is in the expanded state.

Covered prosthetic heart valve

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.

Crimping accessory device for a prosthetic valve

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.

A prosthetic heart valve includes a frame having a plurality of strut members, an inflow end, and an outflow end. 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 has a first layer and a second layer, wherein the second layer has a plush surface. The first layer is folded over a circumferential edge portion of the second layer to form a protective portion that extends beyond the strut members in a direction along a longitudinal axis of the prosthetic heart valve.

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.
