Entac Medical is a predictive analytics company developing noninvasive devices for predictive and diagnostic medicine based on a novel, patented platform technology, Previs Audio Spectral Analysis. The first application, PrevisEA, is a noninvasive, disposable, self-contained device demonstrated in three clinical trials to predict postoperative ileus (POI) in surgical patients. Predicting POI is a $2 billion global market in GI surgery alone. There are no devices or tests currently approved for the prediction of POI. Entac intends to file a 510(k) for PrevisEA in early 2021.
