Abstract

A device for treating tricuspid regurgitation includes a shaft and a first fixation mechanism disposed on a distal end of the shaft. The first fixation mechanism is configured to anchor the device to a first cardiac tissue. The device includes a second fixation mechanism disposed on a proximal end of the shaft. The second fixation mechanism is configured to anchor the device to a second cardiac tissue. The device includes an approximation mechanism connecting the first fixation mechanism and the second fixation mechanism, wherein the approximation mechanism causes the second fixation mechanism to move along the shaft toward the first fixation mechanism to approximate the first cardiac tissue and the second cardiac tissue.
