Proximal, distal, and anterior anchoring tabs for side-delivered transcatheter mitral valve prosthesis

A side delivered mitral valve having a proximal tab anchoring tab component, comprising:

• (i) a self-expanding annular outer support frame, said annular support frame having a central channel, a distal side, and an outer perimeter wall circumscribing a central vertical y-axis in an expanded configuration, said outer perimeter wall having an anterior side, a posterior side, a distal side and a proximal side, said outer support frame covered with a polyester mesh, pericardium-based material or both;
• (ii) a subannular proximal tab mounted on the proximal side of the outer perimeter wall, said proximal tab comprising a wire form extending from 5-20 mm away from the outer perimeter wall and covered with a polyester mesh, pericardium-based material or both;
• (iii) a collapsible inner flow control component mounted within the annular support frame,
• the collapsible inner flow control component having a leaflet frame with 2-4 flexible leaflets mounted thereon, wherein the 2-4 leaflets are configured to permit blood flow in a first direction through an inflow end of the flow control component and block blood flow in a second direction, opposite the first direction, through an outflow end of the flow control component;
• the outer support frame and the leaflet frame comprising diamond- or eye-shaped wire cells made from heat-set Nitinol and configured to be foldable along a z-axis from a rounded or cylindrical configuration to a flattened cylinder configuration, and compressible along the central vertical y axis to a shortened configuration;
• (iv) a distal anchoring tab mounted on the distal side of the annular support frame, wherein the tab is an elongated member attached at a first end to the outer perimeter wall of the annular support frame and has an unattached second end that is heat set to a folded position to press against the outer perimeter wall, wherein the tab engages with a guide wire during deployment to an opened configuration, wherein the tab in the opened configuration tracks over the guide wire allowing the Jab to capture a native posterior leaflet and/or chordae, and upon withdrawal of the guide wire releasing the tab to the folded position, the native posterior leaflet and/or chordae are sandwiched between the folded tab and the outer perimeter wall of the annular support frame;
• wherein the valve is compressible to a compressed configuration for introduction into the body using a delivery catheter for implanting at a desired location in the body, said compressed configuration is oriented along a horizontal x-axis at an intersecting angle of between 45-135 degrees to the central vertical y-axis, and expandable to an expanded configuration having a horizontal x-axis at an intersecting angle of between 45-135 degrees to the central vertical y-axis, and
• wherein the horizontal x-axis of the compressed configuration of the valve is substantially parallel to a length-wise cylindrical axis of the delivery catheter.
