    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.

    摘要： System for fixation of leaflets of a heart valve including an implantable fixation device including a first distal element and a second distal element, a first proximal element moveable relative to the first distal element between a first position and a second position, and a second proximal element moveable relative to the second distal element between a first position and a second position. The system further includes a delivery device including a catheter having a proximal end portion and a distal end portion, the implantable fixation device releasably coupled to the distal end portion of the catheter, the catheter defining at least one lumen extending between the proximal end portion and the distal end portion. The delivery device further includes a first proximal element line extending through the at least one lumen, the first proximal element line coupled to the first proximal element and actuatable to move the first proximal element between the first position and second position, and a second proximal element line extending through the at least one lumen, the second proximal element line coupled to the second proximal element and actuatable to move the second proximal element between the first position and second position. The first proximal element line and the second proximal element line are independently actuatable.
