摘要：
A device for transcatheter gathering of tissue of a heart valve leaflet may include an elongated tube, a capture tool moveable in the tube between a retracted position and an extended position, a tissue support located within a distal portion of the tube, and a clamping member pivotable in the tube between an open position spaced from the tissue support and a closed position adjacent the tissue support. The clamping member may have a flattened clamping portion and a C-shaped portion that defines a pocket therein. An open side of the C-shaped portion may face the tissue support. The capture tool and the clamping member may be operable to gather and clamp tissue between the tissue support and the clamping member, such that the clamped tissue has a gathered configuration. The device may also include a releasable clip adapted to hold the clamped tissue in the gathered configuration.
