1. A system for delivering an implant, comprising:
- a catheter assembly, the catheter assembly having an outer tubular member defining an outer tubular member lumen, an inner shaft member disposed at least partially within the outer tubular member lumen, and a pusher assembly coupled to a distal end portion of a distal inner shaft portion;
a handle;
a trigger operatively coupled to the handle; and
an actuation assembly operatively coupled to the trigger and the catheter assembly, 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 at least one planet gear, a ring gear operatively engaged with the at least one 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 further comprises a shuttle frame having the planet carrier, the at least one planet gear, the sun gear shaft, the ring gear, the first clutch driver and the second clutch driver disposed thereon, and wherein the actuation assembly is configured to displace the outer tubular member in a proximal direction a distance (d) relative to the handle and to separately move the inner shaft member distally a 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 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.

Abstract
A system for delivering an implant including a handle, a trigger, an actuation assembly, and a catheter assembly. The actuation assembly is configured to displace the outer tubular member in the proximal direction and to separately move the inner shaft member distally upon deployment of the trigger from the first position to the second position, and move the inner shaft member proximally with no displacement of the outer tubular member upon return of the trigger from the second position to the first position. The catheter assembly includes an outer tubular member, an inner shaft member, and a pusher assembly.
