ABSTRACT:
Undesirable cross-conduction between electrode pairs in a human-implantable dual channel neurostimulator is prevented. The first and second pairs of electrodes may, optionally, share a common electrode. The first electrode pair is stimulated and then recharged. Then, after a finite waiting period has elapsed, the second electrode pair is stimulated and then recharged. Then, after a finite waiting period, the process is repeated. A high impedance state is established across one of the electrode pairs while the other electrode pair is being stimulated and recharged. Such a high impedance state prevents current from flowing through one of the electrode pairs while the other electrode pair is being stimulated or recharged.
