There are a plurality of workstations including at least one mobile workstation in the external portion. The wireless transmission module is utilized to establish a second communication channel. The apparatus further includes a controller configured to be implanted into the patient. PEG-12 GDO, PEG-12 GDLO, PEG-12 GDM and PEG-12 GDP are particularly suitable for forming liposomes that incorporate tetrahydroflurans in the bilayer. Alternatively, first conductive straps are respectively connected only to first portions of first word lines of a memory device, and second conductive straps are respectively connected only to second portions of second word lines of the memory device, where each first word line is adjacent at least one second word line.
