A pneumatic circuit and other components are provided for the operation of a medical device. In one embodiment of the invention the deformable material is conductive foam, such as metalized foam. A second section, attached to the first section, configured to releasably and reattachably attach to a second location on the package so as to close an opening of the package. High power laser cutting, scribing, and welding results are improved with a combination of modulation and high beam quality while providing for improved processing speeds. Other embodiments include an adjustable controlled compound deposit and control windings with adjustable electrical currents. At least one beam steerer may be provided for adjusting direction of passage of a laser beam through the light passage.
