Abstract: A system comprising a sluice and a catheter. The catheter including an inner, a middle and an outer tube. A stent is disposed in a distal-end portion of the catheter between the inner and outer-tube. The middle-tube ends distally at the proximal end of the stent. An actuating unit having a drive unit provided in the proximal region of the catheter for releasing the stent. A connecting portion is provided between the drive unit and the sluice. The drive unit is cooperating with the middle-tube and the connecting portion where the drive unit is operated the middle-tube is displaced in the distal direction and the actuating unit together with the outer-tube attached thereto is displaced in the proximal direction. The inner-tube is cooperating with the middle-tube and/or the connecting portion and/or the drive unit in such a way that the inner-tube is displaced at least to some extent relative to the actuating unit.

Abstract: A device for applying active substances to surfaces of medical implants (11) has a base station (22) and a replaceable cartridge (10) that can be mounted on the base station, the cartridge (10) having a holder for the implants (11) and also a nozzle for spraying the active substance onto the surface. The base station (22) has a drive unit (75) for moving the holder and the nozzle in relation to each other. For this purpose, the cartridge (10) has a basically cylindrical first housing part (14) which has the holder and a basically cylindrical second housing part (15) which has the nozzle. The first and second housing parts (14, 15) are formed so that they fit into each other and are arranged so that they can be moved, and preferably rotated, relative to each other (FIG. 8).
