Method and system for providing electrical pulses to gastric wall of a patient with rechargeable implantable pulse generator for treating or controlling obesity and eating disorders
First Claim
1. A method of providing electrical pulses with rechargeable implantable pulse generator at one or more sites to the gastric wall of a patient for treating, controlling or alleviating the symptoms for at least one of obesity, inducing weight loss, eating disorders, obsessive compulsive disorders, and motility disorders, 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 two electrodes adapted to be in contact with said gastric wall of a patient, 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
Method and system for providing electrical pulses to the gastric wall of a patient to provide therapy for obesity/eating disorders comprises implantable and external components. The implantable components are a lead and rechargeable 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 rechargeable implanted pulse generator of this embodiment is also 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. Existing gastric stimulators may also be adapted to be used with rechargeable power sources as disclosed herein. The implanted system may also use a lead with two or more electrodes, for 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.
