Abstract:
For the prevention and diagnosis of cardiovascular diseases, the ability to measure cardiac performance is of great importance. A new type of sensor compatible for catheterization is proposed that can diagnose cardiovascular performance while being immune to EMI, as well as compatible with MR imaging, with the ability to expand the number of sensors on a single catheter without additional wires. A prototype consisting of three cascaded pressure sensors on a single optical fiber has been fabricated, allowing measurements of important local medical indicators, such as Fractional Flow Reserve (FFR). The fabricated sensor is able to measure blood pressure with a resolution of 3.6 mmHg at a rate of 2 kHz, with room for improvement. Although further work is needed in the miniaturization and integration of the sensor in a catheter, preliminary measurements show promising results.
