Fiberoptic sensor for noninvasive measurement of variceal pressure.

We present a newmeasuring probe based on a miniature fiberoptic pressure sensor that can measure esophageal variceal pressure. The probe consists of an outer flexible chamber filled with a pressure transmission medium, at the center of which is positioned the fibreoptic sensor with diameter of 0.5mm (FOP-F125, FISO Technologies Inc., Quebec, Canada) (●" Fig… CONTINUE READING
