Electrodes, Implanted

	Auditory Brain Stem Implants - Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
	Cochlear Implants - Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.
	Defibrillators, Implantable - Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia and ventricular fibrillation. They consist of an impulse generator, batteries, and electrodes.
