The Codman-Hakim Programmable Valve is widely used in shunting hydrocephalus and other conditions.
To establish an accurate valve verification system for the Codman-Hakim programmable valve that does not require radiographic exposure.
Prospective clinical trial tested a new valve verification system at 9 research sites.
The Valve Programming and Verification System allowed us to establish the valve setting in 62% of subjects with a programmable valve.
The Valve Programming and Verification System avoids radiation exposure, is cost-effective, and time efficient for the patient and provider. In approximately one third of subjects, those in whom "adjustment complete" is not achieved, cranial radiographs are still needed.
