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.

Abstract: Catheter assembly for delivering an implant including an outer tubular member, an inner shaft member, and a pusher assembly. The outer tubular member defines an outer tubular member lumen and includes an inner layer, a reinforcement layer, a middle layer, and an outer layer. The inner shaft member is disposed at least partially within the outer tubular member lumen. The inner shaft member includes a proximal inner shaft portion and a distal inner shaft portion, the distal inner shaft portion having a distal end portion. The pusher assembly is coupled to the distal end portion of the distal inner shaft portion. The inner shaft member is configured to move distally and proximally relative the outer tubular member between an initial position and a deployed position.
