Claim Text:
1. A fully implantable medical system comprising: bimodal electrode structure, placeable in contact with a selected surface region of a subject's diaphragm at a location out of contact with the subject's heart, and having one operating mode for sensing cardiac-cycle electrical activity discernible at the selected surface region, and another, independent, operating mode for applying asymptomatic electrical stimulation to the diaphragm at the selected surface region; and electrical circuit structure operatively connected to the electrode structure for receiving therefrom information corresponding to the subject's cardiac-cycle electrical activity sensed by the electrode structure, the electrical circuit structure operable to note a presence of a valid electrical V-event in such received cardiac-cycle electrical-activity information, and to deliver asymptomatic, cardiac-cycle-synchronized, electrical stimulation through the electrode structure to the diaphragm in a predetermined timed relationship to the valid electrical V-event, the electrical stimulation for a purpose of triggering a biphasic motion of the diaphragm, which biphasic motion comprises a caudal motion of the diaphragm followed by a cranial motion of the diaphragm.
