## Indications for use
The ReFlow® System Mini and the ReFlow® Mini Flusher, used as components of a shunt system, are for use in the treatment of patients with hydrocephalus or conditions where draining or shunting of cerebrospinal fluid (CSF) is medically indicated. The miniaturized ReFlow Mini Flusher may be used by a qualified clinician as a tool to facilitate a noninvasive retrograde fluid flush of the shunt ventricular catheter to unblock inlet holes to restore, increase, or maintain CSF flow. When used with the ReFlow Ventricular Catheter, the flush can also open the ReFlow Ventricular Catheter’s relief membrane to restore, increase, or maintain CSF flow. The ReFlow System Mini components are not intended to change the diagnosis, treatment, or follow-up of patients with proximal catheter occlusions. Under the care, direction, and instruction of the treating physician, the ReFlow Mini Flusher may be used as directed for noninvasive flushing by a trained healthcare professional in-clinic or by a trained caregiver or adult patient in a non-clinical environment.
