Detection of Upper Gastrointestinal (GI) Bleeding Using a Novel Bleeding Sensor Capsule -A Pilot Study

This is a multi-center, prospective, non-randomized, open-label, exploratory clinical investigation performed to evaluate safety and effectiveness of the PillSense System when used for detection of blood in the stomach of patients suspected to have an Upper Gastrointestinal Bleed (UGIB).

The PillSense System consists of the PillSense Capsule, an atraumatic, ingestible, and disposable capsule and PillSense Receiver, an external real-time monitor for results display. The PillSense Capsule is a non-invasive, single use device designed to detect blood in the stomach and wirelessly transmit the data to the external PillSense Receiver. The receiver is a handheld device which displays real-time information gathered from the capsule and clearly displays results, "Blood Detected" or "No Blood Detected". All enrolled participants were admitted for suspected UGIB and were required to ingest a PillSense Capsule followed by esophagogastroduodenoscopy (EGD) within 1 hour of PillSense Capsule administration. All Patients underwent standard endoscopy following PillSense Capsule evaluation and results were compared with the PillSense System result, i.e., "Blood Detected" or "No Blood Detected". The study was also designed to confirm transit of the PillSense Capsule through the GI tract and patient tolerability of the PillSense Capsule.
