Abstract
Measurement of a physiological pressure is accomplished by placement of a pressure transmitting catheter within a blood vessel or other structure within which pressure is to be measured. The catheter is blood-compatible, capable of withstanding handling during distribution and implantation, and provides adequate pressure transmission frequency response in a variety of applications. The catheter, which includes a hollow flexible tube filled with a low viscosity fluid and having a plug of a gel-like material at its distal end, transmits the pressure signal to a solid-state transducer which is typically connected to amplifying electronics and an implantable radio-transmitter capable of relaying the pressure information from within the body to a radio receiver located external to the body.
