  • Body fluid pressure monitor
    Patent number: 4172449
    Abstract: Body fluid pressure is monitored by implanting a sensor in the body which is responsive to the pressure therein. The sensor communicates with radiopaque means which changes its position when there is an abnormal amount of pressure as compared to a normal amount of pressure whereby the change can thereby be detected by X-Ray and translated into a value indicative of the pressure, thereby permitting serial, comparative, reliable and permanent recording in a relatively inexpensive manner.
