The present invention relates to a coating assembly and methods that employ the coating assembly to control the thickness of therapeutic or other coatings delivered to a medical device during a coating process. The device includes a slide channel that narrows in a direction toward an intersection with a barrel channel. 2 dm2 and the layer has been produced by employing ultra short pulsed laser deposition wherein pulsed laser beam is scanned with a rotating optical scanner including at least one mirror for reflecting the laser beam. Actuating members capable of being operated by an operating mechanism included in the casing are connected to the movable members of the hinged joints. The passing on of the refresh instruction to the respective memory segment is interrupted if the segment-specific refresh time has not yet expired. The central computer may then send a signal to a telephone dialing device assigned to the wireless pendant, causing the device to dial an emergency telephone number.
