ABSTRACT:
An apparatus for indicating the fluid flow through implanted shunts by temperature sensing. The sensor comprises a series of thermistors carried by a flexible substrate mounted on a rigid support. The sensors are placed in external proximity to a section of the implanted shunt and by varying the temperature of the fluid proceeding the test section, the apparatus will determine the rate of flow therethrough. Each thermistor is connected by conductors to scaling and amplification circuitry for input into a computer system.
