1. An apparatus for evaluating cerebrospinal fluid (CSF) flow rate or flow status in a CSF shunt applied to the body of a patient for transmitting said CSF between first and second locations of said body, said apparatus comprising:

  • a pad that is placed against the skin of a patient over the location of the CSF shunt, said pad comprising a pair of temperature sensors that are aligned in a first direction to form an upstream temperature sensor and a downstream temperature sensor with respect to the shunt, said pad further comprising a third temperature sensor that is not aligned in said first direction, each of said temperature sensors generating respective temperature data; and

    a sensor processing device that is electrically coupled to said pad for receiving temperature data from each of said temperature sensors, said sensor processing device using said temperature data to determine a flow rate or flow status of said CSF through said shunt when a temperature source is applied to said pad.
