A voltage regulating method applied to a memory to regulate a word line voltage corresponding to a set of memory cells of the memory includes the following steps. The bone anchor implantation devices and methods find particular application in maintaining or improving urinary continence by suspending or stabilizing the bladder neck. Embodiments may also provide a high magnitude negative voltage to erase; a low impedance, low voltage current to read or program; and burn little to no current when not coupled to a memory cell that is selected to be erased. In the de-energized state, the blade is advanced and used as a traditional, mechanical surgical blade.
