Abstract: Embodiments of the present disclosure are directed to devices and methods for treating tricuspid valve insufficiency. For example, in some embodiments, a tricuspid insufficiency treatment device is provided, and includes a tubular member configured for implantation within a vena cava of a patient, where the tubular member is formed with a sidewall. The device also includes at least two (2) valves arranged circumferentially along the sidewall, where each valve comprises an opening formed in the sidewall, and a blocking member arranged to block and unblock a respective opening of the plurality of openings. Each blocking member comprises 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.

Abstract: Embodiments of the subject disclosure are directed a tricuspid valve treatment device, as well as associated methods for treating and/or replacing a diseased or otherwise damaged tricuspid valve using, for example, such disclosed devices and systems) is provided. In some embodiments, the device includes a lateral outflow port configured for arrangement after implantation in the right atrium, or right atrium and right ventricle, and configured for the fixation of a surgical or transcatheter valve, where such valve can be placed after the tricuspid valve treatment device is implanted.
