Paper Abstract

Rapid development of fiber optic sensing technology promises better devices for medical practice. In this paper, a new fiberoptic catheter-tip blood pressure transducer is presented. During measurement, pressure is applied through a side port to a cantilever structure to cause a combined linear and angular displacement of the optical fibers with respect to a fixed reflector, thus modulating the input carrier light. At the signal processing module, a signal proportional to the applied pressure is generated. Factors affecting the performance of the new transducer have been carefully examined during its development and are discussed. In-vitro experimental results have demonstrated the promising performance of this transducer. It is capable of direct blood pressure measurement for assessment of cardiac and arterial functions.
