Local internal pressure measurement system of cerebral aneurysm model using ultra-miniature fiber-optic pressure sensor

Local internal pressure measurement system of cerebral aneurysm model has been developed for the quantitative evaluation of the therapeutic effects of the coil embolization. For local pressure measurement at multi point, an ultra-miniature fiber-optic pressure sensor, of which diameter is 125 μm and measurement system which has four channel optical switch has been developed. In this study, the cerebral aneurysm model equipped with two fiber-optic pressure sensors was fabricated and the pressure measurement of two sensors was performed.
