An implant includes a prosthetic valve and is transitionable from a compressed to an expanded state. The implant includes a frame assembly including a plurality of struts that collectively define an upstream-frame-assembly-perimeter at an upstream end of the frame assembly and a downstream-frame-assembly-perimeter at a downstream end of the frame assembly. The frame assembly includes a valve frame that defines a lumen, and one or more appendages disposed at and extending in a downstream direction from the downstream-frame-assembly-perimeter. A plurality of prosthetic leaflets are disposed within the valve frame lumen and facilitate one-way upstream-to-downstream fluid flow through the lumen. The implant includes a fabric and, in the expanded state of the implant, the fabric obscures the one or more appendages and defines a downstream perimeter of the fabric at a downstream end of the implant. Additional embodiments are described.

Prosthetic valve with appendages

A frame assembly () includes a tubular portion () that defines a lumen along an axis; a plurality of arms () coupled to the tubular portion at a first axial level, each of the arms extending radially outward from the tubular portion to a respective arm-tip; and a plurality of ventricular legs () that are coupled to the tubular portion at a second axial level, and that extend radially outward from the tubular portion. A first sheet () has a greater perimeter (), and a smaller perimeter () that defines an opening. The first sheet is stitched onto the plurality of arms, with the opening aligned with the lumen. Subsequently, an outer perimeter () of a second sheet () is stitched to the greater perimeter of the first sheet. Subsequently, the second sheet is everted by passing an inner perimeter () of the second sheet around the arm-tips.

Prosthetic heart valve

A valve body circumscribes a longitudinal axis and defines a lumen along the axis. Upstream arms are coupled to the valve body, and extend radially outward from the valve body to respective arm-tips. Downstream legs are coupled to the valve body, and extend radially outward from the valve body and toward the plurality of arms. A flexible pouch extends radially outward from the valve body. The arms and the legs narrow the pouch therebetween to form a narrowed portion of the pouch, thereby defining, in an interior space of the pouch: (a) an inner portion, radially inward from the narrowed portion, and in fluid communication with the lumen, and (b) an outer portion, radially outward from the narrowed portion, and in fluid communication with the inner portion via the narrowed portion. Other embodiments are also described.

Prosthetic heart valve with pouch

A frame assembly includes a valve body, a plurality of arms that each extend radially outward from the valve body to a respective arm-tip, and a plurality of ventricular legs that are coupled to the valve body and that extend radially outward from the valve body and toward the plurality of arms. A liner lines the lumen. Prosthetic leaflets are attached to the liner within the lumen. A first sheet of flexible material is attached to the plurality of arms. A second sheet of flexible material is attached to the first sheet and extends radially inwards and downstream, and is attached to the valve body. The first sheet, the second sheet, and the liner define an inflatable pouch therebetween. The apparatus defines a plurality of windows from the lumen into the pouch.
