Abstract: The invention relates to a system for the wireless monitoring of neural activity via minimally invasive, repositionable means. The use of either optical or direct electrical galvanic communications has the advantage of being safe over a wide range of parameters and allows high rates of reliable analog or digital communications. A small component that is typically driven in an untethered way is integrated with a mechanism that can register electric voltage between at least two points and transmit the resulting recorded signal. A repositionable, small component allows for versatile and safe monitoring of different intracranial sites. A wireless reliable communication method allows reconstructing high-fidelity signals and thus understanding brain activity in places that are otherwise inaccessible.

Abstract: There is provided improved therapy methods and apparatus for treating a patient's brain and spinal cord. The apparatus further relates to a flexible surgical balloon or cap-like device comprising one or more material layers that may have an antimicrobial element. The therapy apparatus may include portals for introducing diagnostic monitoring and/or therapeutic devices, and delivery of therapeutic drug delivery systems. Certain embodiments of the invention have an output emission area positioned to irradiate a portion of the brain with an efficacious power density and wavelength of light for diagnostic and/or therapeutic purposes.
