Embodiments of the invention are directed to a medical device and methods for immobilizing and retrieving material from a patient’s body. The operating unit has a tensile testing device as well as a device for transferring a yarn to the tensile testing device. The router suitably incorporates photonic wavelength selective optical adddrop filters and multiplexers. Further, the system may be utilized as part of a system for producing and tuning super-oxygenated and structured water. A number of photographable images and remaining time for recording a moving image which are calculated from a capacity of a storage medium are preferably displayed in combination in accordance with combinations of the number of pixels and the compression rate.
