    摘要： Fixation device for fixation of leaflets of a heart valve, the fixation device including a central element defining a central axis. The fixation device further includes a distal portion including at least one arm coupled to the central element, wherein the at least one arm is moveable to a selected position between a fully open position and a fully closed position. The distal portion further includes at least one leg operatively coupled to the at least one arm and configured to move the at least one arm to the selected position between the fully open position and the fully closed position. The at least one arm includes a contact portion configured to engage native heart valve tissue, the contact portion defining a contact portion axis. The distal portion includes a flexure portion configured to enable the contact portion in the selected position to move within a flex angle range between an undeformed contact portion angle relative to the central axis and a flexed contact portion angle relative to the central axis. The flexed contact portion angle is greater than the undeformed contact portion angle. The flex angle range is about 10 degrees to about 45 degrees. The fixation device further includes at least one gripping element moveable relative to the at least one arm to capture a native leaflet therebetween.
