Abstract

See full text

A method of determining a local cerebrospinal fluid flow rate. The method including the steps of positioning a distal end of the catheter in a flow of cerebrospinal fluid of the patient, the catheter including an infusion port and at least one temperature sensor positioned at a fixed distance from the infusion port, infusing a bolus of a temperature controlled fluid through the infusion port into the flow of cerebrospinal fluid, and monitoring a temperature sensed by the at least one temperature sensor, wherein a change in the temperature sensed by the at least one temperature sensor over time is representative of a local cerebrospinal fluid flow rate in proximity to the infusion port.
