A self-expanding element delivery apparatus includes a catheter having an inner lumen, a self-expanding element, and a delivery wire disposed within and extending through the inner lumen and the self-expanding element. The self-expanding element has a proximal, distal, and an intermediate portion. The element has anchor members, a compressed configuration fitting within the inner lumen, and an expanded configuration dimensioned larger than the catheter. The delivery wire also has proximal and distal portions, an intermediate portion, a dual function bump member disposed approximate to the intermediate portion, and a pusher bump member disposed approximate to the proximal portion of the delivery wire. A bump member distance between the dual function bump member and the pusher bump member is such that so that only one of the dual function bump member and the pusher bump member can contact one of the anchor members.
