    摘要： Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.

    摘要： System for fixation of leaflets of a heart valve including a delivery catheter having an elongated shaft, a proximal end portion and a distal end portion configured to be positioned proximate native leaflets of a heart valve from a remote vascular access point, the delivery catheter further includes a rotatable actuator rod having a threaded fastener at a distal end thereof, and a fixation device releasably coupled by a threaded connection to the threaded fastener of the actuator rod. The fixation device includes a first arm moveable between a closed position and an open position, and a second arm moveable between a closed position and an open position. The fixation device further includes a first gripping element movable relative to the first arm in the open position, the first gripping element biased toward the first arm to capture a first leaflet of the heart valve therebetween and a second gripping element movable relative to the second arm in the open position, the second gripping element biased toward the second arm to capture a second leaflet of the heart valve therebetween. The first gripping element is biased toward the first arm, and the second gripping element is biased toward the second arm. The fixation device further includes a covering disposed on each of the first gripping element and the second gripping element.

    摘要： System for fixation of leaflets of a heart valve including a delivery catheter having an elongated shaft, a proximal end portion and a distal end portion configured to be positioned proximate native leaflets of a heart valve from a remote vascular access point, the delivery catheter further includes a rotatable actuator rod having a threaded fastener at a distal end thereof, and a fixation device releasably coupled by a threaded connection to the threaded fastener of the actuator rod. The fixation device includes a first arm moveable between a closed position and an open position, a second arm moveable between a closed position and an open position. The fixation device further includes a first gripping element movable relative to the first arm in the open position, the first gripping element biased toward the first arm to capture a first leaflet of the heart valve therebetween, and a second gripping element movable relative to the second arm in the open position, the second gripping element biased toward the second arm to capture a second leaflet of the heart valve therebetween. The first gripping element and the second gripping element each includes a plurality of barbs extending therefrom, the plurality of barbs of each of the first gripping element and the second gripping element being aligned transversely in at least one row. The fixation device further includes a covering disposed on each of the first gripping element and the second gripping element, wherein the plurality of barbs of the first gripping element and the second gripping element, respectively, protrude through the covering.
