FIXATION DEVICES, SYSTEMS AND METHODS FOR ENGAGING TISSUE
First Claim
1. A system for fixation of leaflets of a heart valve comprising:
- 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; and
a fixation device releasably coupled to the delivery catheter, the fixation device comprising;
a first arm moveable between a closed position and an open position;
a second arm moveable between a closed position and an open position;
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;
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,wherein the first gripping element and the second gripping element each comprises 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; and
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.

Abstract
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, and a fixation device releasably coupled to the delivery catheter. 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 and the second gripping element each include 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.
