1. A method of transcutaneously implanting a stimulation electrode in a peritoneal cavity of a patient using transgastric mapping and guidance, the method comprising:

  • inserting an endoscope having a proximal end and a distal end through a mouth into a stomach;

    passing the distal end of the endoscope through an opening in the stomach into the peritoneal cavity;

    retroflexing the distal end of the endoscope to orient the distal end of the endoscope towards a diaphragm, the retroflexed distal end of the endoscope configured to bend at least 90 degrees;

    inserting a mapping instrument having a mapping electrode through the endoscope and into the peritoneal cavity, the mapping instrument adapted to pass through the retroflexed endoscope;

    using the endoscope to place the mapping electrode in contact with the diaphragm of the patient within the peritoneal cavity;

    using the mapping electrode, coupled to a mapping stimulator, to map electrical activity in the diaphragm; and

    transcutaneously positioning a stimulation electrode using a percutaneous needle into the peritoneal cavity under visualization from the endoscope based on the mapped electrical activity in the diaphragm.
