ABSTRACT:
The device and method for placement of an instrument, specifically electrodes, in the GI tract allows for placement of electrodes for gastric electrical stimulation into the gastric wall using endoscopic techniques. The device has one or more electrodes disposed on an elongated body having a pointed first end and a bolster disposed on a second end. When placed within the GI tract, the first end of the device extends through the gastric and abdominal walls, extending outside of the patient's body with the bolster in contact against the inner lining of the gastric wall to retain the device. Exposed electrodes contact the gastric smooth muscle. Insulated wires in electrical connection with-the electrodes run the length of the device body. Once the device is placed, the first end of the device body is removed to expose the wires, allowing electrical connection to an external electrical signal generator to provide electrical stimulus.
