Abstract
Esophageal pressure, bile content and pH in the gastroesophageal apparatus are important parameters to be monitored in gastroesophageal diseases. An all-optical device was developed for their simultaneous measurement and utilizes a catheter where plastic optical fibres for the measurement of bile and pH and a glass fibre with FBGs for pressure monitoring are integrated. The interrogation device contains two different modules: one for the pressure monitoring based on the measurement of the wavelength shift of the grating peaks, and the other one for bile and pH measurement, based on absorption changes caused by the esophageal content.
