Abstract
A leaflet capture device and system, and an assembling method. The leaflet capture device comprises: a wire body configured to be spiral and comprising a distal coil, an intermediate coil, and a proximal coil which are arranged in sequence; and a proximal joint comprising a proximal joint main body portion, a proximal clamping jaw, and a proximal clamping portion. The proximal clamping jaw is arranged on one end of the proximal joint main body portion; the proximal clamping portion is arranged on the other end of the proximal joint main body portion; the proximal joint is provided with a proximal through hole passing the proximal clamping jaw through the clamping portion via the proximal joint main body portion; a proximal end portion of the proximal coil is clamped in the proximal clamping jaw after being fixed to the proximal joint main body portion; the proximal through hole is communicated with the proximal end portion of the proximal coil; the proximal clamping portion is fitted to a releasable portion of a delivery device; a pushing member of the delivery device abuts against the proximal end portion of the proximal coil via the proximal through hole. The leaflet capture devi…
