1. A self-expanding element delivery apparatus, comprising:
a catheter comprising an inner lumen;
a self-expanding element comprising:
a proximal end;
a distal end;
an intermediate portion located between the proximal end and the distal end;
a proximal anchor member disposed at the proximal end;
a distal anchor member disposed at the distal end;
a compressed configuration dimensioned to fit within the inner lumen of the catheter; and
an expanded configuration dimensioned larger than the catheter;
wherein the self-expanding element is in the compressed configuration when disposed within the inner lumen, and
wherein the self-expanding element is in the expanded configuration when disposed outside the inner lumen;
a delivery wire disposed within and extending through the inner lumen and the self-expanding element, comprising:
a proximal portion consisting of a pusher bump member disposed approximate to the proximal portion of the delivery wire, the pusher bump member being proximal of the proximal anchor member and unengaged to the self-expanding element;
a distal portion;
an intermediate portion located between said proximal and distal portions of the delivery wire, consisting of a dual function bump member disposed approximate to the intermediate portion of the delivery wire, the dual function bump member being confined inside the self-expanding element by the proximal anchor member and the distal anchor member; and
a bump member distance between the dual function bump member and the pusher bump member so that only one of the dual function bump member and the pusher bump member can contact one of the distal anchor member and the proximal anchor member.
