1. System for inserting a self-expandable occluder into a patient and for releasing the occluder in the left atrial appendage of the patient, the system comprising the occluder and_an insertion unit which has a drive unit and has an insertion catheter comprising an outer tube and an inner tube extending through the outer tube, wherein a proximal end region of the occluder is movement-coupled to the outer tube, and wherein a distal end region of the occluder is movement-coupled to the inner tube, wherein, in order to release the occluder, the drive unit interacts with the inner tube and the outer tube such that, when actuated, the inner tube can be moved in a distal or proximal direction and the outer tube can be moved in the proximal direction or distal direction, so that the distal end and the proximal end of the occluder can be moved away from or toward one another, wherein, during insertion of the occluder, a distal end of the outer tube is disposed inside the occlude, wherein the outer tube comprises at least one latching finger-like end portion at its distal end region, and wherein the latching finger- like end portion cooperates with the proximal end region of the occluder only when the inner tube is disposed inside the outer tube.
