The capsule is a physiologic battery-powered device used for gastric monitoring and data collection. The tethered pH capsule is swallowed by the patient. The information gathered by the capsule contains one or more gastric parameters (i.e., pH, events and or gastric bleeding, delayed stomach emptying, or gastric dumping). The capsule is comprised of a sensor for monitoring gastric pH and movement. The telemetric signals produced by the pH capsule are detected by the patient worn transceiver. The capsules data is transmitted from the transceiver to the Heidelberg Interface module. The interface module sends the capsule information to the computer. The computer software interprets the capsule data and displays it on computer generated graph. This is a single-use device.
