A medical device disposed about a distal end portion of the inner tubular member. A proximal stopper is provided having a distal end and disposed proximal to a proximal end of the movable tubular structure. The distal end of the proximal stopper is spaced from the proximal end of the movable tubular structure at least a longitudinal length dimension of the medical device, wherein the outer tubular member and the movable tubular structure are movable in a proximal direction up to engagement of the proximal stopper to deploy the medical device from the inner tubular member.
