An improved medical implant device is provided which has a plurality of micro-electrodes. The resilient electrode plate separators extend beyond the peripheral edges of the electrode plates in the plate stack of the battery and a) encapsulate, at least the major surfaces and certain portions, preferably all, of the electrode plate edges, and b) form electrolyte reservoirs within the battery external of the plate stack. The latch contacts the limiting member with the latch in an open position. The flexure carriage has four first cross members disposed between adjacent pairs of elongate columns and arranged to interconnect the first ends. The method also recognizes faults in the power section based on the evaluation of the phase current. The aerosolized particles having a uniform diameter in the range of about 1 to 5 microns are inhaled into a patient’s lungs and thereafter reach the patient’s circulatory system.
