Abstract
Esophageal pressure, bile content and pH are important parameters in gastroesophageal diseases. An all-optical technology is described capable to perform simultaneously oesophageal manometry, pH-metry and bilimetry. The three different sensors were integrated in a single optical fibre catheter for the simultaneous measurement of the three parameters. The optoelectronic prototype for the interrogation of the catheter is constituted by two separate optoelectronic modules for the interrogation of the pressure sensor and for the bile and pH sensors, respectively. The prototype and the optical catheter are compliant with European Directives on medical devices in terms of electromagnetic compatibility, electrical safety and biocompatibility.
