Two prisms bonded together in a bonding step are then, in a pressing step, put onto a joining jig and pressed to be formed into an optical device. In particular, the present invention provides novel compositions and methods for using desmethylselegiline for selegiline-responsive diseases and conditions. The present invention can form a cover metal layer covering over the top surface and the two side surfaces, even the under surface of the metal structure, by one single photomask. and under moderately elevated pressure. For example, in accordance with an embodiment of the present disclosure, an improved catheter assembly comprises a tube member, having a first end and a second end with a lumen extending therebetween, and a balloon, wherein the balloon is in fluid communication with the lumen and is threadably coupled to the tube member. The elimination of the per-connection timestamps has no negative effect on the delay bounds guaranteed by the scheduler.
