Patent ID: 8641749

Claim:
A delivery system for the introduction of a self-expanding stent into a body vessel, the delivery system comprising: a self-expanding stent with a hollow cylindrical body and a proximal and a distal end, in which at least the proximal end has projecting loops pointing alternately in the proximal and distal direction, the loops having a shoulder and straight sections, an outer tube which passes through the stent and an inner tube which passes through the outer tube, the inner tube and the outer tube being designed to move axially with respect to one another, and a locking system for the projecting loops at the proximal end of the stent for introduction of the stent into the body vessel, the locking system having a cap element with pins fixed to it which point axially away from the cap in the proximal direction of the delivery system and a first engagement unit for the pins which is positioned proximal with respect to the cap element in the delivery system, wherein the cap element is fixed to the inner tube in such a way that movement of the inner tube in the distal direction can release the projecting loops at the proximal end of the stent from the locking system and allow them to expand, wherein the first engagement unit for the pins pointing in the proximal direction of the delivery system is fixed to the outer tube in such a way that the first engagement unit and the cap element can move axially with respect to one another.
