What is it indicated for?
The Alivio Ventricular Catheter and Flusher System (Alivio System) is for use in the treatment of patients with hydrocephalus, as components of a shunt system when draining or shunting of cerebrospinal fluid (CSF) is indicated. The Alivio Flusher may be used by a qualified clinician as a tool to facilitate a non-invasive retrograde fluid flush of the Alivio Ventricular Catheter to unblock inlet holes or open its relief membrane to restore or increase CSF flow in a non-flowing shunt. The Alivio Flusher is not intended to change standard care practices for diagnosis, treatment, or follow-up of patients with proximal catheter occlusions.
Indications for use as stated in the FDA summary.
