摘要:
Valve repair devices and systems configured to detect proper valve leaflet insertion. The device/system can have a pair of paddles and a clasp attached to each of the paddles. The clasps may have a fixed arm attached to the paddle, a movable arm connected to the fixed arm that is movable between an open position and a closed position, and an indicator arm connected to at least one of the fixed arm and the movable arm. The indicator arm can move between a first position when not engaged with a leaflet and a second, engaged position when engaged with the leaflet. Movement of the indicator arm from the first position to the second, engaged position indicates capture of a leaflet of the native valve by the pair of paddles.
