Wireless Device with Energy Management for Closed-Loop Deep Brain Stimulation (CLDBS)

Deep brain stimulation (DBS) is an effective and safe medical treatment that improves the lives of patients with a wide range neurological psychiatric diseases, has been consolidated as first-line tool in last two decades. Closed-loop deep (CLDBS) pushes this further by automatically adjusting parameters to response real time. The main contribution paper low-size/power-controlled, compact complete CLDBS system simultaneous acquisition channels, neurostimulation channels wireless communication. Each channel low-noise amplifier (LNA) buffer differential configuration eliminate DC signal component input. Energy management efficiently done control communication unit. battery supports almost 9 h both circuits active. If only circuit used Open Loop DBS, can hold sufficient voltage for 24 operation. whole low-cost portable therefore it could be wearable device.
