Apparatus and method of implantable bidirectional wireless neural recording and stimulation

摘要

A device and method is described for electronic human prosthetics, and specifically a skull- and/or spine implantable bi-directional neural-communication/brain-machine interface (BBMI) device where the input, output and on-board computing are combined into a single unit to form a compact neuro-prosthetics device. This invention is also directed to a fully implantable wireless spinal electronic recording and stimulation system using the BBMI in a human. The bi-directional devices (BBMIs) communicate with other bi-directional brain-machine interface devices (BBMI) and/or with external controllers wirelessly. The compact implantable stimulator has ultrasonic secondary battery charging system. One or more BBMI can be wirelessly connected so that a closed loop of BBMIs, or a BBMI and an external controller, can wirelessly send trigger pulses to this fully implanted stimulator over the spinal cord.
