Abstract: A system including an implantable neurostimulator device capable of modulating cerebral blood flow to treat epilepsy and other neurological disorders. In one embodiment, the system is capable of modulating cerebral blood flow (also referred to as cerebral perfusion) in response to measurements and other observed conditions. Perfusion may be increased or decreased by systems and methods according to the invention as clinically required.

Abstract: Described here are intracranial ferrules, systems, and methods for sensing and stimulating neural tissues. The ferrules are generally designed to include a holding area for retaining an implantable device. In some variations, the ferrule itself may perform the sensing and stimulating functions. In other variations, the ferrule may function to sense data from neural tissues and the implantable device may function to stimulate neural tissues. In yet other variations, the ferrule may function to stimulate, and the implantable device may function to sense data from, the neural tissues. The sensing and stimulating functions may be used to detect and/or treat various neurological conditions.

Abstract: This patent relates to an apparatus and method for assessing a subject's hearing by recording steady-state auditory evoked responses. The apparatus generates a steady-state auditory evoked potential stimulus, presents the stimulus to the subject, senses potentials while simultaneously presenting the stimulus and determines whether the sensed potentials contain responses to the stimulus. The stimulus may include an test signals having a number of different components and modulations. The apparatus may further perform a number of objective audiological tests. The apparatus is further adapted to perform multi-modality testing in which more than one sensory modality of the subject is tested simultaneously.

Abstract: This patent relates to an apparatus and method for screening a subject's hearing by recording steady-state auditory evoked responses. The apparatus generates a steady-state auditory evoked potential stimulus having a plurality of stimulus components, presents the stimulus to the subject, senses potentials while simultaneously presenting the stimulus and determines whether the sensed potentials contain a plurality of responses to the stimulus.

Abstract: In a medical procedure to treat a patient in a deep coma, an electrode is implanted on the vagus nerve (tenth cranial nerve) in the patient's neck. A selected pulse train is generated and applied to the electrode as a treatment for the deep coma. The patient's brain waves are collected, amplified and digitized before, during and after the treatment, and compared, using a computer system, against a reference (the patient or/and a normal group) to determine if the treatment is helping the patient.
