Abstract
A system for delivering an implant including a handle, a trigger, and an actuation assembly. The actuation assembly can include 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, and a second clutch driver. The actuation assembly can be configured to displace the outer tubular member in the 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 move the inner shaft member proximally a distance (y) relative to the handle with no displacement of the outer tubular member upon return of the trigger from the second position to the first position.
