Abstract
The present invention relates to a delivery system for a self-expanding stent with a hollow cylindrical body and a proximal and a distal end. At least the proximal end thereof has projecting loops pointing alternately in the proximal and distal direction, the loops having a shoulder and straight sections. In addition, there is 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. In addition, it is fitted with 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 pin elements fixed to it which point axially in the proximal direction of the delivery system and a first engagement unit for the pin elements which is positioned proximal with respect to the cap element in the delivery system.
