The disclosure pertains to a medical device deployment system comprising a restraint member which holds the embolic protection filter in a restrained, or partially collapsed, state for insertion into a lumen and transit to a desired deployment site. The display package can be a blister package, a clam shell package, or a similar package containing product such as cosmetics. The laying head comprises a fixed containing and protecting bell element enclosing a portion of the rotating bell element and having a shape that is complementary thereto. However, unlike existing CGI programs, the persistent CGI program is not automatically terminated after output is transmitted to the web browser by the web server application. The key enables four functional positions by means of a quarter-circle turn: both outlets open, one outlet open and another closed and both outlets closed. The surgical instrument has a movement detection device to detect a movement sequence of the surgical instrument and the HF surgical unit has an evaluation device for evaluating a movement sequence detected by the detection device.
