Benefits of technology

"The current invention provides a system for providing pulses to the gastric wall to treat obesity, eating disorders, and inducing weight loss. The system includes a rechargeable implantable pulse generator that can be powered by an external stimulator or a rechargeable battery. The pulses can be delivered to the gastric wall using a coil and can have various parameters such as amplitude, width, and frequency. The system can also be controlled remotely and the implantable device can have multiple electrodes made of different materials. The technical effects of the invention include improved therapy for obesity and related disorders, as well as improved weight loss methods."

Problems solved by technology

But, the requirements of gastric pacing are significantly different from those of cardiac pacing.

Embodiment Construction

[0084] In the method and system of this invention, a lead 40 comprising at least one pair of electrodes for providing gastric myo-electrical stimulation is laprscopically implanted in a patient. In one preferred procedure methodology, a patient undergoing general endotracheal anesthesia is positioned in lithotomy position. A minimum of three trocars are inserted. A midline supraumbilical port is used to introduce the optical system. Another port is used to introduce the stomach grasper. One other port (a subcostal port) is used to introduce the lead and subsequently the needle-driver. The back end of the lead is brought out through this left subcostal port at the completion of the abdominal portion of the operation.

[0085] The lead is then introduced into the abdomen, and inserted into a muscle tunnel. Using appropriate counter-traction on the stomach, both of the electrodes are ensured to be buried within the tunnel wall. After the electrodes have been inserted, a flexible fiberopt...

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.

Description

[0001] This application is a continuation of application Serial No. 11 / 035,374 filed Jan. 13, 2005, entitled “Method and system for providing electrical pulses for neuromodulation of vagus nerve(s) using rechargeable implanted pulse generator”, which is a continuation of application Ser. No. 10 / 841,995 filed May 8, 2004, which is a continuation of application Ser. No. 10 / 196,533 filed Jul. 16, 2002, which is a continuation of application Ser. No. 10 / 142,298 filed on May 9, 2002. The prior applications being incorporated herein in entirety by reference, and priority is claimed from these applications.FIELD OF INVENTION [0002] This invention relates generally to electrical stimulation therapy for gastrointestinal (GI) disorders, more specifically to gastric myo-electrical pacing therapy for obesity and eating disorders with rechargeable implantable pulse generator. BACKGROUND [0003] Obesity is a significant health problem in the United States and many other developed countries. Obesit...
