Small Diameter Selective Organ Perfusion Catheter with Fiber-optic Pressure Sensor

Abstract

A small diameter (O.D. 1.47 mm) selective organ perfusion catheter with fiber-optic pressure sensor for monitoring perfusion pressure has been fabricated. As a design of the tip of the sensor, non-opening type and opening type have been fabricated and the opening design decrease influence by external force such as load or the balloon inflation on catheter down to 1 - 2 mmHg and achieved error range ±3 mmHg in the pressure measurement range of 0 - 100 mmHg.
