Abstract: Presented herein are hybrid multi-phasic stimulation techniques for stimulation of tissue of a recipient of an implantable medical device. In particular, in accordance with the hybrid multi-phasic stimulation techniques, at least one stimulation current pulse is delivered to the tissue of the recipient in order to stimulate the tissue. The at least one stimulation current pulse injects charge into the tissue that is then removed through the combination of at least one discharging current pulse and a period of electrode shorting.
