Abstract: An apparatus and method for adjunct (add-on) therapy of depression, migraine, neuropsychiatric disorders, partial complex epilepsy, generalized epilepsy and involuntary movement disorders comprises an implantable lead-receiver, and an external stimulator having controlling circuitry, a power source, and a coil to inductively couple the stimulator to the lead-receiver. The external stimulator emits electrical pulses to stimulate a cranial nerve such as the left vagus nerve according to a predetermined program. In a second mode of operation, an operator may manually override the predetermined sequence of stimulation.

Abstract: An apparatus and method for adjunct (add-on) therapy of dementia and Alzheimer's disease comprises an implantable lead-receiver, an external stimulator having controlling circuitry and a power source, and an electrode to inductively couple the stimulator to the lead-receiver. The external stimulator emits electrical pulses to stimulate a cranial nerve such as the left vagus nerve according to a predetermined program selected from at least two predetermined programs.

Abstract: An apparatus and method for adjunct (add-on) therapy of painful syndromes comprises an implantable lead-receiver, an external stimulator having controlling circuitry and a power source, and an coil to inductively couple the stimulator to the lead-receiver. The external patch contains means for compensating for the change in axis of external transmitting and internal receiving coils. The external stimulator emits electrical pulses to stimulate a cranial nerve such as the left vagus nerve according to a predetermined program. The pre-determined programs include both short term and long term stimulation.
