Abstract
A system for mechanically deploying intraluminal implants is disclosed. The system is used with an implant that is delivered and/or deployed via a pull wire and includes a handle having a funnel and receiving channel for receiving the pull wire, a slider having a thumb grip and a wedge, and a shuttle having a grabber for grasping the pull wire. The thumb grip is pulled proximally to retract the wedge to cause the grabber to grasp the wire and retract the shuttle but not the wire. An extension spring linked between the slider and the shuttle abruptly pulls the shuttle to retract the pull wire after the slider is fully retracted.

2. A handle for retracting a pull wire, the handle comprising:
-
a slider movably mounted to said handle and having a resting position, a priming phase, and a deployment position, said slider further comprising a trip; a shuttle movably mounted to said handle, the shuttle having a resting position and a retracted position, and further comprising a wire gripper for engaging a pull wire, and a latch comprising a latched position and an unlatched position; and a spring linking said shuttle to said slider; wherein said slider is movable by a user from said resting position, through said priming phase, and to said deployment position, and wherein when said slider is moved from said resting position through said priming phase, said wire gripper is configured to engage said pull wire, said spring is elongated to store energy therein; and
when said slider is moved to said deployment position, said trip releases said latch from said latched position to said unlatched position, and said shuttle is thereby retracted by said spring to its deployed position, thereby retracting the pull wire. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
