The IntraMarX capsule can be used for the diagnosis of many GI conditions, including chronic constipation, colonic inertia, hypomotility and outlet delay. Each of the IntraMarX capsules contains 24 tiny radiopaque rings within the capsule shell. The capsule is swallowed by the patient under the direction of physician. As this capsule moves through the digestive system, the capsule shell will dissolve and leave the rings in the GI tract of the patient; which will show up later during an X-ray scan. Five days after swallowing the capsule, a single scan of the abdomen will be taken to see the location of the rings and how many are left in the GI tract of the patient. The physician will make evaluations based on the rings remaining and make a diagnosis of GI conditions of the patient.
A battery-powered (conventional or physiologic), electronic component of a gastrointestinal telemetric monitoring system designed to be swallowed by a patient for the wireless signal transmission of one or more gastrointestinal parameters (i.e., pH, pressure, temperature) or events (e.g., gastrointestinal bleeding). The capsule contains a sensor(s) and the telemetric signals it produces are detected by an extracorporeal (e.g., patient-worn) receiver or transceiver; information is displayed by the receiver, or transmitted by the transceiver to a computer with software for display. The capsule is excreted from the gut. This is a single-use device.
