CORTICAL INTERFACE FOR MOTOR SIGNAL RECORDING AND SENSORY SIGNAL STIMULATION

摘要

The present invention consists of an implantable device with at least one package that houses electronics that sends and receives data or signals, and optionally power, from an external system through at least one coil attached to the at least one package and processes the data, including recordings of neural activity, and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that is/are attached to the at least one package. The invention, or components thereof, is/are intended to be installed in the head, or on or in the cranium or on the dura, or on or in the brain. Variations of the embodiments depend on the physical locations of the coil(s), package(s) and array(s) with respect to the head, cranium, dura, and brain. Novel features of the present invention include the small size of the implantable package which houses the controller, the high number of electrodes that are provided for stimulation and/or sensing and stimulation, and the methods for manufacturing such a device. These features have unique applications in neural stimulation to treat or prevent disorders or disease.
