Tricuspid regurgitation control devices for orthogonal transcatheter heart valve prosthesis

An orthogonally-deliverable prosthetic heart valve, the prosthetic valve comprising:

• an outer frame defining a central channel that extends along a central axis of the outer frame, the outer frame forming a plurality of compressible wire cells having an orientation and cell geometry that allows compression of the outer frame in an axial direction parallel to the central axis, the outer frame further forming a pair of hinge points that allow folding of the outer frame along a long-axis that extends through the hinge points;
• a flow control component disposed within the central channel and coupled to the outer frame, the flow control component having an inner frame and a set of leaflets coupled to the inner frame, the flow control component configured to permit blood flow in a first direction through an inflow end of the prosthetic valve to an outflow end of the prosthetic valve and to block blood flow in a second direction, opposite the first direction;
• and
• a regurgitation control component disposed within the central channel and coupled to a drum that is attached to a top edge of the outer frame to cover a portion of the central channel adjacent to and outside of the inner frame of the flow control component, the regurgitation control component configured to selectively permit a controlled regurgitation in the second direction,
• the prosthetic valve configured to be folded along the long-axis and compressed along the central axis to place the prosthetic valve in a compressed configuration for orthogonal delivery via a delivery catheter, the long-axis being substantially parallel to a length-wise axis of the delivery catheter when the prosthetic valve is disposed therein, the prosthetic valve configured to transition to an expanded configuration when the prosthetic valve is released from the delivery catheter.
