Indications The CODMAN VPV Programmer is designed for use only with the CODMAN® HAKIM® Programmable Valves in the treatment of hydrocephalus when shunting cerebrospinal fluid (CSF) from the ventricles of the brain. It is used to noninvasively adjust the CODMAN® HAKIM® Programmable Valve to the selected setting and provides confirmation of the valve adjustment, without the need for radiographic imaging when an “adjustment Complete” message is displayed.
