The development of a fiber optics pressure catheter is proposed for NHLBI Subject 56.D, 1991. The optical pressure sensor using elasto-optic materials would be the smallest in diameter (less invasive) among currently available electronic and optical pressure catheters. It is inserted into blood vessels (arteries, veins or heart chamber) and is capable of measuring blood pressures (O to 300 mmHg) with a very high accuracy (better than 3 mmHg). The sensor is bio-compatible and causes no medical problems. The sensor is also stable over long time periods (72 hrs.) and for temperature changes (30 to 50 degrees centigrade). The manufacturing cost of the sensor head would be very inexpensive (less than $lO) so that it can be disposable. The sensor will help monitor heart conditions after open heart surgery. Because of its small size, the sensor can be used for infants. The primary commercial application of this device will be in cardiology. It can also be used to monitor fluid pressures in the human brain after surgery. The Phase I effort demonstrated the feasibility of the proposed approach. Prototype development will be carried out in Phase II.

提出了一种用于NHLBI的光纤压力导管的研制 实验对象56.D，1991年。采用弹性光学的光学压力传感器 材料的直径最小（侵入性较小）， 目前可用的电子和光学压力导管。是 插入血管（动脉、静脉或心室）， 能够测量血压（0至300 mmHg）， 准确度（优于3 mmHg）。该传感器具有生物相容性， 医疗问题。传感器在长时间内也是稳定的（72 小时）以及温度变化（30至50摄氏度）。的 传感器头的制造成本将非常便宜（小于 10美元），以便它可以是一次性的。 该传感器将有助于监测心脏直视手术后的心脏状况。 由于其体积小，传感器可用于婴儿。主 该装置的商业应用将在心脏病学中。它也可以 用于监测手术后人脑中的流体压力。的 第一阶段的工作证明了拟议办法的可行性。 原型开发将在第二阶段进行。
