System and method for providing electrical pulses to the vagus nerve(s) to provide therapy for obesity, eating disorders, neurological and neuropsychiatric disorders with a stimulator, comprising bi-directional communication and network capabilities

A system and method for providing pulsed electrical stimulation to one or both vagus nerve(s) of a patient to provide therapy for obesity, eating disorders, neurological and neuropsychiatric disorders. The electrical pulses can be provided either unilaterally or bilaterally (left and right vagus nerves) and can be supra-diaphramatic or be sub-diaphramatic. The system comprising implantable stimulator, lead(s), an external stimulator, and a programmer. The implantable stimulator, comprising a pulse generator module, and a stimulus-receiver module which is used in conjunction with an external stimulator. Control circuitry ensures selective operation of one of the modules of the implanted stimulator, at a time. Further, the external stimulator comprises a telemetry module for remotely activating (or de-activating) programs over the internet, to arrive at the optimal program for each patient. Once the optimal “dose” is titrated using the external stimulator, the implanted pulse generator can then be programmed to similar parameters. The external stimulator in conjunction with the implanted stimulus-receiver can override the implanted pulse generator module, to provide extra dose of therapy, and also to conserve the implanted battery. The external stimulator is networked to other computers. Using the networking, a physician situated remotely can monitor and program the devices, as well as, automatically generate invoicing. In one embodiment, the external stimulator also comprises GPS circuitry for locating patient.

Technique for using heat flow management to treat brain disorders

A method of treating a brain disorder by heat transfer from brain tissue comprising the steps of surgically cutting a heat transfer aperture into a patient's skull, thereby exposing a predetermined portion of patient's brain; surgically implanting into said heat transfer aperture a heat pump having one or more electrical sensor elements and one or more temperature sensor elements; surgically implanting a heat transfer management unit in a body cavity of said patient such that a micro controller of the heat transfer management unit is connected to one or more activity sensor elements and one or more temperature sensor elements contacting brain tissue and connecting the heat transfer management unit to said heat pump via a lead bundle. Optionally, the heat transfer unit may be located external to the patient's body. Responsive to signals from one or more activity or temperature sensor elements, mathematical algorithms of the heat transfer management unit determine abnormal brain activity, causing the heat pump to remove heat from the brain tissue into a heat sink, thereby cooling the predetermined portion of the patient's brain. This technique utilizes acute hypothermia by means of a Peltier cooler or similar device to cool the brain temperature to reduce or prevent seizure initiation and/or propagation. The method may be used in association with brain stimulation and/or drug application to acutely avoid the occurrence of a seizure episode.
