Claim:
1. An actuation assembly for an implant delivery system having a handle, a trigger, an outer tubular member and an inner shaft member, the inner shaft member being disposed within the outer tubular member and movable distally and proximally relative to the outer tubular member, the actuation assembly comprising: a planet carrier; at least one planet gear operatively coupled to the planet carrier; a sun gear shaft operatively engaged with the planet gear; a ring gear operatively engaged with the planet gear; a first clutch driver configured to limit the sun gear shaft to uni-directional rotational motion; and a second clutch driver configured to uni-directionally lock the sun gear shaft and the planet carrier; wherein the actuation assembly is operatively coupled to the trigger and the inner and outer tubular members, and configured to displace the outer tubular member in the proximal direction a first distance (d) relative to the handle and to separately move the inner shaft member distally a second distance (x) relative to the handle upon deployment of the trigger from a first position to a second position, and further wherein the actuation assembly is configured to move the inner shaft member proximally a third distance (y) relative to the handle with no displacement of the outer tubular member relative to the handle upon return of the trigger from the second position to the first position.
