Micro Optical Pressure Sensor
-
Micro – No need for high-priced solid-state pressure catheters when a mass manufactured glass fiber is inexpensive and small, i.e. as small as 0.9 Fr (310 µm). Low noise – Since a beam of light is inherently quiet, no EMI/RF from the catheter itself are interfering with the pressure signal. Plus, it isn’t influenced by high EMI/RF environments. The sensors can be made long enough to be used for MRI image gating. Accurate – Due to the speed of light, the frequency response depends entirely on the signal conditioner. The fast 15 kHz FISO-LS conditioner ensures high fidelity pressure traces. No signal artifact – The sensor is located at the tip of the fiber, which allows the measurement of the target signal without any signal artifact due to the vessel or cardiac wall contact with the sensor.
