Abstract
The present invention discloses various methods and systems for positioning a guide wire between a patient'"'"'s mouth and a skin site via an implant tract in a stomach. The method includes locating the desired tissue site in the stomach, such as with an endoscope or other suitable instrument. In some embodiments the desired tissue site is marked inside the stomach with a visible dye or light visible from the peritoneal cavity. An implant tract is created through the stomach wall at the desired tissue site, either from “inside-out” or “outside-in”. The implant tract may be made using a RF catheter, RF guide wire, an endoneedle, or other suitable instrument. The size of the implant tract depends on the device to be placed there, such as a stimulation lead. Diameter sizes of the tract may vary from 0.014″ to 0.250″. An access hole or access port is created at a skin site, using a Verres needle, RF catheter, RF guide wire, an endoneedle, or other suitable instrument. A guide wire is then positioned through the implant tract, access port and mouth, such that the guide wire extends between the mouth and the skin site access port via the implant tract in the stomach.
