Method and apparatus for wireless charging of a bioelectronic device implanted in a laboratory animal or in a human being

Abstract

The invention relates to an apparatus for charging a remote feedable circuit bioelectronic implanted in a patient or in a laboratory animal, said apparatus comprising a composable container configured to define a closed environment suitable to receive a patient or a laboratory animal, said container comprising a plurality of composable walls made of a nonmagnetic material and connected to each other so as to define said closed environment, said container comprising at least one first winding whose axis is arranged in a first direction (Z) and at least one second winding whose axis is arranged in a second direction (Y) perpendicular to said first direction (Z). The apparatus further comprises a system for powering and driving the windings of the composable container, said system comprising a switching power driver for each winding, a plurality of phase locked loop circuits respectively connected to each switching power driver and connected to a programmable logic circuit of the powering and driving system, said programmable logic circuit being configured to perform a phase comparison, the programmable logic circuit being in turn connected to a microprocessor of the powering and driving system, said microprocessor being configured to provide driving signals to the windings for generating inside the container a rotating magnetic field.
