SUBARACHNOID FLUID MANAGEMENT METHOD AND SYSTEM

A CSF management method for use with a patient forms a closed loop CSF circuit between two points on the patient's body. The CSF circuit has a therapeutic inlet to receive a therapeutic material (e.g. a drug), and a pump having a pump outlet to direct CSF along the CSF circuit. The method contr...

Zusammenfassung:	A CSF management method for use with a patient forms a closed loop CSF circuit between two points on the patient's body. The CSF circuit has a therapeutic inlet to receive a therapeutic material (e.g. a drug), and a pump having a pump outlet to direct CSF along the CSF circuit. The method controls the pump to direct CSF from the pump outlet at a CSF rate that is different from the natural flow rate (i.e., the natural CSF flow rate). The therapeutic material is added to the CSF via the therapeutic input at a therapeutic rate. The CSF rate is different than the therapeutic rate and/or may be greater than the therapeutic rate. Alternative methods may control a bolus drug infusion to localize the application to a target region.
