Methods and systems for delivering an implant
First Claim
1. A trigger assembly for an implant delivery system having 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 and an actuation assembly configured to displace the inner shaft member distally and proximally relative to the outer tubular member:
- a trigger functionally connected to the actuation assembly by a driving rack; and
a gear train functionally disposed between the trigger and the driving rack;
wherein the gear train comprisesa trigger gear sector,a trigger pinion operatively meshed with the trigger gear sector,a slide pinion operatively coupled to the trigger pinion, anda slide rack disposed on a slide coupled to the driving rack and operatively meshed with the slide pinion,wherein the driving rack is configured to move the inner shaft member distally relative the handle and the outer tubular member proximally relative the handle.

Abstract
A system for delivering an implant including a handle, a trigger, and an actuation assembly. 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.
