<p>The present application relates to one or more devices for repairing a cardiac valve. The device(s) can comprise a catheter assembly configured to pass from a remote vasculature of a patient to a position within the heart adjacent the cardiac valve, and at least two maneuverable grasping elements independently translatable through the catheter assembly, the grasping elements being reversibly and radially extendable from the catheter assembly to capture and reposition portions of at least two valve leaflets into an apposed position. The device(s) can further comprise a fastening mechanism translatable through the catheter assembly to secure the stabilized portions of the two valve leaflets, and a capture triggering mechanism including one or more sensors configured to detect the position of the valve leaflets with respect to the grasping elements, where the grasping elements extend in response to an indication that the leaflets are within a predetermined distance therefrom.</p> |
