1080i: Wireless Biosensing of Upper Gastrointestinal Bleeding: A Paradigm Shift in Diagnosis and Treatment

Abstract

Upper GI bleeding (UGIB) accounts for approximately 300,000 hospitalizations per year in the U.S. Rebleed rates following UGIB can be as high as 20%, even after endoscopic intervention, and can lead to higher morbidity and mortality. We have developed an endoscopically implantable wireless biosensor which detects acute GI hemorrhage and specifically re-bleeding. The sensor emits a wireless emergency signal to medical personnel using Bluetooth technology.
