AFFECT Study for Patients With Intraventricular Hemorrhage, Subarachnoid Hemorrhage, Subdural Hematoma, and Ventriculitis

"IRRAflow® Active Fluid Exchange System is an intracranial drainage system intended for use by professional medical hospital personnel, trained and experienced in neurosurgical medical care.~The intracranial pressure is kept at a safe level by draining excessive intracranial fluid. The system incorporates an irrigation support mechanism, used to irrigate the system in a controlled, programmed manner to minimize catheter occlusion. Additionally, a manual bolus can be given to facilitate keeping the catheter clear of occlusion or to clear the catheter of occlusion if one is present. This mechanism works by producing a bolus pulse using short periods of high flow (i.e. flow pulses)."

The External Ventricular Drain (EVD) is used standard of care at the study site for ventricular drainage.
