A system for delivering an implant , the implant disposed within a distal end portion of an outer tubular member and positioned to be engaged by a distal end portion of an inner shaft member when the inner shaft member is moved distally relative to the outer tubular member, the inner shaft member being disposed within the outer tubular member and movable distally and proximally relative to the outer tubular member, comprising: a handle ; a trigger operatively coupled to the handle; an actuation assembly including a planetary gear system, the planetary gear system having a planet carrier , at least one planet gear operatively engaged with the planet carrier , a sun gear shaft operatively meshed with the at least one planet gear , a ring gear operatively meshed with the at least one planet gear , and a first clutch driver configured to limit the sun gear shaft to uni-directional rotational motion; a ratchet mechanism functionally coupled to the trigger; a driving rack and a gear train functionally disposed between the trigger and the driving rack , the gear train having a trigger gear sector , a trigger pinion operatively meshed with the trigger gear sector , a slide pinion operatively coupled to the trigger pinion , and a slide rack disposed on a slide coupled to the driving rack and operatively meshed with the trigger pinion ; wherein the sun gear shaft is functionally coupled to the outer tubular member to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and the ring gear is coupled by a ratchet rack to the inner shaft member 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 first clutch driver allows the ring gear 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. a handle ; a trigger operatively coupled to the handle; an actuation assembly including a planetary gear system, the planetary gear system having a ratchet mechanism functionally coupled to the trigger; a driving rack and a gear train functionally disposed between the trigger and the driving rack , the gear train having a trigger gear sector , a trigger pinion operatively meshed with the trigger gear sector , a slide pinion operatively coupled to the trigger pinion , and a slide rack disposed on a slide coupled to the driving rack and operatively meshed with the trigger pinion ; wherein the sun gear shaft is functionally coupled to the outer tubular member to displace the outer tubular member in the proximal direction a distance (d) relative to the handle and the ring gear is coupled by a ratchet rack to the inner shaft member 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 first clutch driver allows the ring gear 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. a trigger gear sector , a trigger pinion operatively meshed with the trigger gear sector , a slide pinion operatively coupled to the trigger pinion , and a slide rack disposed on a slide coupled to the driving rack and operatively meshed with the trigger pinion ; <EOS>
