  • Patent number: 11980543
    Abstract: A transcatheter valve prosthesis is disclosed that has a compressed, delivery configuration and an expanded configuration for deployment within a native heart valve. The valve prosthesis includes a self-expanding frame and a prosthetic valve component. The self-expanding frame includes a valve receiving portion defining an opening therethrough and first and second anchors at opposing ends of the valve receiving portion. The valve receiving portion is substantially planar and the first and second anchors are oriented substantially perpendicular to the valve receiving portion when the valve prosthesis is in the expanded configuration. The prosthetic valve component is disposed within the opening of the valve receiving portion and secured thereto.

  • Patent number: 11857413
    Abstract: A prosthetic heart valve including a stent frame and a valve structure. The valve structure is disposed within a lumen of the stent frame. The stent frame is configured to self-expand from a compressed condition for transluminal delivery. The stent frame has a lattice structure forming a tubular shape defining a circumference and a plurality of closed cells arranged to define a band exhibiting a variable radial stiffness. The prosthesis can be deployed such that the band applies a minimal force on to anatomical locations relating to the heart's conductive pathways. A region of the band otherwise having low radial stiffness is located at or over a conductive pathway upon final implant.

  • Publication number: 20210077258
    Abstract: A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.
