A device for gathering tissue of a heart valve leaflet may include an outer tube extending in an elongated direction, a capture tool moveable in the outer tube between a contained position and a use position, and a tissue securing component disposed at a distal end of the outer tube and adapted to be applied to tissue captured by the capture tool and to hold the captured tissue in a gathered configuration. The capture tool may include two grasping members that are moveable relative to one another in the elongated direction. Each grasping member may have a proximal portion and a plurality of fingers or barbs. The grasping members may be operable to capture tissue of the heart valve leaflet therebetween and to draw the captured tissue into the outer tube in the gathered configuration.
