Endoscopic system for attaching a device to a stomach
First Claim
1. A system for attaching a functional device to a stomach wall wherein the functional device is configured to perform a therapeutic or diagnostic function at the stomach, the system comprising:
- an attachment device having a first portion arranged to extend into the stomach wall when said attachment device is attached to the stomach wall; and
an endoscopic delivery device comprising;
an elongate member having a proximal end and a distal end;
an attachment device engaging portion coupled with the elongated number, said attachment device engaging portion arranged to advance the attachment device through an esophagus and towards an attachment site within the stomach.

Abstract
A device, system and method for diagnosing and treating gastric disorders is provided. A functional device resides within the patient?s stomach and is secured to the stomach wall by an attachment device. The functional device may be a sensor for sensing various parameters of the stomach or stomach environment, or may be a therapeutic delivery device. The functional device in one embodiment provides a device, system and method for gastric electrical stimulation where stimulating electrodes are secured to the wall of the stomach by the attachment device or otherwise. A preferred device includes: at least one stimulating electrode in electrical contact with the stomach wall; an electronics unit containing the electronic circuitry of the device; and an attachment mechanism for attaching the device to the stomach wall. The functional devices may be programmed to respond to sensed information or signals. An endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall. The endoscopic instruments attach or remove the attachment devices and functional devices from the stomach and may be used to assist in determining the optimal attachment location.

14. A method for treating or diagnosing a patient comprising the steps of:
-
providing a functional device configured to perform a therapeutic or diagnostic function at the stomach, placing a guide from within the stomach with a portion of the guide extending into the stomach wall at an attachment site;
coupling the functional device to the guide; and
guiding the functional device with the guide to the attachment site from within the stomach.
