A minimally invasive wirelessly powered brain stimulation system for treating neurological disorders

Area of Science:

• Biomedical Engineering
• Neuroscience
• Medical Devices

Background:

• Neurological disorders such as Alzheimer's disease and epilepsy pose significant treatment challenges.
• Current therapeutic interventions often lack efficacy or involve invasive procedures.

Purpose of the Study:

• To introduce and evaluate a novel, minimally invasive, wirelessly powered medical device for treating neurological disorders.
• To assess the efficacy of a magnetic induction extra-cranial brain stimulation (MI-ECBS) system in canine models.

Main Methods:

• Development of a wirelessly powered MI-ECBS system capable of delivering high frequency stimulation (HFS) and low frequency stimulation (LFS).
• Application of HFS (1mA, 10Hz) and LFS (1Hz) protocols to canine models.
• Monitoring of electroencephalogram (EEG) power spectrum to assess neuro-modulation effects.

Main Results:

• Successful demonstration of complementary neuro-modulation, including facilitation and inhibition, using the MI-ECBS system.
• EEG power spectrum analysis confirmed the modulation effects.
• Achieved a 39.57x enhancement in stimulation delivery efficacy compared to conventional transcutaneous direct current stimulation (tDCS).

Conclusions:

• The novel MI-ECBS system offers a promising minimally invasive therapeutic approach for Alzheimer's disease and epilepsy.
• Wireless power and precise waveform delivery enhance stimulation efficacy.
• The system demonstrates significant advantages over existing tDCS methods.
