Open the CIPO recordAbstract From the Canadian patent
A stimulation system including a stimulator having a multi-channel electrode array utilizing a monopolar electrode configuration. A processor is operatively coupled to the stimulator. The processor is configured to determine a channel interaction (CI) sequence using simultaneous sign-, correlated pulses and channel interaction compensation. The CI sequence has a CI pulse rate and a CI mean pulse amplitude and produces resulting potentials , that are substantially equal to desired potentials at given positions relative to the multi-channel array. The CI sequence may include temporal gaps between pulses, wherein the processor may be configured to increase the CI pulse rate such that the …
