Abstract

A system is provided for endoscopically attaching a functional device to a stomach wall wherein the functional device is configured to perform a therapeutic or diagnostic function at the stomach.

Claims

1-178. -178. (canceled)

179. 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;

a quick connect mechanism configured to connect the attachment device with the functional device to attach the functional device to the stomach wall; and

an endoscopic delivery device comprising;

an elongate member having a proximal end and a distal end;

a functional device engaging portion extendable through a lumen extending through said elongate member, said functional device engaging portion arranged to advance the functional device through an esophagus and towards the attachment device when attached at an attachment site within the stomach.

237. The system of claim 179 further comprising a functional device engaging tool wherein said functional device engaging tool comprises a releasable connector and wherein said functional device further comprises a tool connector, said releasable connector arranged to releasably engage the tool connector for functional device deployment

238. The system of claim 179 wherein said attachment device comprises:

an expandable distal portion coupled to said first portion, said expandable distal portion arranged to secure the attachment device to the stomach wall.

239. The system of claim 179 further comprising a guide coupled to the attachment device and wherein said functional device includes a guide opening for receiving the guide.

240. The system of claim 239 wherein said guide comprises a tether.

241. The system of claim 239 wherein said guide comprises a guide wire.

242. The system of claim 179 wherein the functional device comprises an electrical stimulator configured to stimulate a portion of the stomach wall.

180-236. -236. (canceled)

243. A system for providing electrically stimulating signals to a stomach wall comprising:

a) a gastric stimulator including;

at least one stimulating electrode;

a housing having electronic circuitry contained therein and including an electrical conductor arranged to electrically couple the at least one electrode to the electronic circuitry, wherein the electronic circuitry is configured to deliver electrically stimulating signals to the stomach wall through at least one stimulating electrode; and

an attachment device operative to attach the housing to the inside of stomach wall; and

an electrode anchor arranged to attach the at least one electrode to the stomach wall; and

b) an endoscope comprising;

an elongate member having a proximal end and a distal end;

a stimulator engaging portion located at said distal end of the elongate member, said stimulator engaging portion arranged to advance at least a portion of the gastric stimulator through an esophagus and towards an attachment site within the stomach.

244. The system of claim 243 wherein the electrode anchor comprises a first portion arranged to extend into the stomach wall.

245. The system of claim 244 wherein the first portion comprises a first narrow profile for extending into the stomach wall;

further comprising a second portion having a first narrow profile position similar to the first narrow profile of the first portion and a second expanded profile position in which the second portion engages the stomach wall to prevent withdrawal of the attachment device from the stomach wall.

246. The system of claim 244 wherein said first portion comprises an expandable distal portion arranged to secure the electrode attachment mechanism to the stomach wall.

247. The system of claim 245 wherein the at least one electrode is located on said first portion of the attachment device.
