Medtronic ManoScan ESO high resolution manometry system

Name: Medtronic ManoScan ESO high resolution manometry system
Brand: ManoScan

ManoScan ESO is a high resolution oesophageal manometry system used in GI physiology labs to measure the pressure and motor function of the oesophagus and its sphincters, for example in dysphagia, achalasia and pre-operative reflux work up. A solid state catheter with 36 circumferential sensors builds a continuous pressure topography map, which ManoView software analyses against the Chicago Classification.

Safety

Safety warnings from the record.

Catheters have become stuck in the nose or oesophagus after studies, sometimes needing sedation or ENT and endoscopic removal and causing nasal trauma. Source
Several disinfectants, including Rapicide, Sterilox, hydrogen peroxide and Sporox, are not approved and may damage the catheter or change its performance. Source
Wrong timing of thermal compensation can move IRP across the 15 mmHg threshold and change the diagnosis in some studies. Source
