Claim 0:
1. A valve leaflet capture device, comprising:
a wire body, configured in a spiral shape, comprising a distal coil, a middle coil and a proximal coil that are sequentially arranged, wherein the distal coil is arranged at a distal end of the wire body, and the proximal coil is arranged at a proximal end of the wire body, wherein both a spiral inner diameter of the proximal coil and a spiral inner diameter of the distal coil are greater than a spiral inner diameter of the middle coil; and
a proximal joint, comprising a proximal joint body, a proximal clamping jaw and a proximal clamping portion, wherein the proximal clamping jaw is arranged at one end of the proximal joint body, the proximal clamping portion is arranged at an other end of the proximal joint body, and the proximal joint is provided with a proximal through-hole that runs through the proximal joint body from the proximal clamping portion to the proximal clamping jaw, and a proximal end of the proximal coil is clamped in the proximal clamping jaw after being fixed to the proximal joint body, the proximal clamping jaw is configured to tightly clamp the proximal end of the wire body after fixing the proximal end of the wire body to the joint body, the proximal through-hole is in communication with the proximal end of the proximal coil, and the proximal clamping portion is configured for clamping a releasable portion of a delivery device, and a pushing member of the delivery device pushes against the proximal end of the proximal coil through the proximal through-hole.
