Abstract
An active implantable medical device (AIMD), for electrical stimulation of a tissue includes a light source, lodged in an encapsulation unit, for delivering optical energy pulses of optical power (Popt). A stimulation optical fibre for transferring optical energy from the light source of the encapsulation unit to the tissue coupling unit is also provided. The tissue coupling unit is configured for being coupled to a tissue to be electrically stimulated by electrodes (65) belonging to an electrical circuit. The PV-unit includes Us units arranged in series, each unit having Pp photovoltaic cells (PV-cells) arranged in parallel. Us and Pp, ∈N, and Us×Pp=N=constant. The electrical circuit includes switches configured for varying the values of Us and alternatively or concomitantly, the light source is an addressable optical emitters array.
