Zusammenfassung:To provide leaflet clips, devices and methods for introducing leaflet clips into a heart valve.SOLUTION: A leaflet clip has an elongated member including a proximal end portion and a distal end portion, and first and second clipping arms movable between an open position and a closed position. The clipping arms include respective proximal end portions coupled to the proximal end portion of the elongated member, and respective distal end portions extending distally and radially outward relative to the elongated member. The leaflet clip further includes a tubular member coaxially disposed about the elongated member. Axial motion of the tubular member relative to the elongated member or axial motion of the elongated member relative to the tubular member causes corresponding movement of the clipping arms between the open and closed positions.SELECTED DRAWING: Figure 1 【課題】弁尖クリップを心臓弁内に導入する弁尖クリップおよびデバイスおよび方法を提供する。【解決手段】弁尖クリップが、近位端部分および遠位端部分を含む細長部材と、開位置と閉位置との間で移動可能な第1のクリッピングアームおよび第2のクリッピングアームとを有する。クリッピングアームは、細長部材の近位端部分に結合されたそれぞれの近位端部分と、細長部材に対し遠位方向かつ径方向に外側に延びるそれぞれの遠位端部分とを含む。弁尖クリップは、細長部材の周りに同軸で配置された管状部材を更に備える。細長部材に対する管状部材の軸方向運動または管状部材に対する細長部材の軸方向運動によって、開位置と閉位置との間でクリッピングアームの対応する動きが生じる。【選択図】図1
