Method and system to provide therapy for obesity and other medical disorders, by providing electrical pules to symapthetic nerves or vagal nerve(s) with rechargeable implanted pulse generator
First Claim
1. A method of providing electrical pulses with a rechargeable implantable pulse generator for stimulation and/or blocking of sympathetic nerve(s), or its branches, or part thereof in a patient for treating, controlling, or alleviating the symptoms for at least one of obesity, eating disorders, and inducing weight loss, comprising the steps of:
- providing said rechargeable implantable pulse generator, comprising a microcontroller, pulse generation circuitry, rechargeable battery, battery recharging circuitry, and a coil;
providing a lead with at least one electrode(s) adapted to be in contact with said sympathetic nerve(s) or its branches or part thereof, and in electrical contact with said rechargeable implantable pulse generator;
providing an external power source to charge said rechargeable implantable pulse generator; and
providing an external programmer to program said rechargeable implantable pulse generator.

Abstract
A method and system for providing electrical pulses to splanchnic nerve(s) and/or around celiac ganglion for selective sympathetic stimulation of a patient, to provide therapy for obesity or to induce weight loss comprises implantable and external components. The implantable components are a lead and an implantable pulse generator, comprising rechargeable lithium-ion or lithium-ion polymer battery. The external components are a programmer and an external recharger. In one embodiment, the implanted pulse generator may also comprise stimulus-receiver means, and a pulse generator means with rechargeable battery. The implanted stimulus-receiver is adapted to work in conjunction with an external stimulator. In another embodiment, the implanted pulse generator is adapted to be rechargeable, utilizing inductive coupling with an external recharger. The implanted system may also use a lead with one or more electrode(s), for sympathetic nerve(s) modulation with selective stimulation and/or blocking. In another embodiment, the external stimulator and/or programmer may comprise an optional telemetry unit. The addition of the telemetry unit to the external stimulator and/or programmer provides the ability to remotely interrogate and change stimulation programs over a wide area network, as well as other networking capabilities.
