Abstract

The present invention relates to a device for inserting a self-expanding stent into a body vessel. The device comprises a tube, a pushing element and a grip having a housing via which the pushing element is secured on the grip. Further, the device comprises a stent carrier and a moveable element, the latter of which is guided in the housing of the grip and is coupled to the pushing element. Moving the movable element in the proximal direction effects a movement of the pushing element in the distal direction and a movement of the tube in the proximal direction.
