Systems, methods and devices for treating tricuspid insufficiency

A tricuspid insufficiency treatment device comprising:

• a tubular member configured for implantation within a vena cava of a patient, the tubular member formed with a sidewall,
• and
• at least three (3) valves arranged in a single adjacent grouping along the sidewall, each valve comprising:
• an opening formed in the sidewall, and
• a blocking member comprising a flap or cover pivotally attached at or proximate a portion of a respective opening and arranged to block and unblock the opening during ventricular systole and ventricular diastole, respectively, such that the opening is unblocked in a direction opposite to the attachment of the flap or cover,
• wherein each of the valves is hinged to the tubular member along different sides such that each blocking member opens away and in a different direction from each of the other blocking members.

A tricuspid insufficiency treatment device comprising:

• a tubular member configured for implantation within a vena cava of a patient, the tubular member formed with a sidewall,
• and
• a centralized grouping of at least three (3) valves arranged along the sidewall, each valve comprising:
• an opening formed in the sidewall, and
• a blocking member comprising a flap or cover pivotally attached at or proximate a portion of a respective opening and arranged to block and unblock the opening during ventricular systole and ventricular diastole, respectively, such that the opening is unblocked in a direction opposite to the attachment of the flap or cover,
• wherein
• the tubular member comprises an expandable stent having a plurality of cells,
• each of the plurality of cells includes a first rhombus shape,
• each opening for each of the at least three valves correspond to a specific respective cell of the stent, and
• the blocking member includes a second rhombus shape that corresponds to the first rhombus shape.

A tricuspid insufficiency treatment device comprising:

• a tubular member configured for implantation within a vena cava of a patient, the tubular member formed with a sidewall,
• and
• at least three (3) valves arranged circumferentially along the sidewall, each valve comprising:
• an opening formed in the sidewall, and
• a blocking member comprising a flap or cover pivotally attached at or proximate a portion of a respective opening and arranged to block and unblock the opening during ventricular systole and ventricular diastole, respectively, such that the opening is unblocked in a direction opposite to the attachment of the flap or cover,
• wherein each blocking member includes a length of shape reinforcing wire arranged and running only along substantially the entire the perimeter thereof.
