Outcome Measures
Primary Outcomes (1)
Percentage of Participants Who Achieved "Adjustment Complete" and a Consensus X-ray Reading
Up to 5 attempts to achieve "Adjustment Complete" using the Codman Valve Position Verification (VPV) system for each Subject. Agreement in 2 of 3 valve X-ray readings by independent radiologists for each Subject was considered "consensus X-ray". All participants included achieved "Adjustment Complete" and a "consensus X-ray reading".
Day 1
Secondary Outcomes (1)
Percentage of Agreement Between the Codman Valve Position Verification (VPV) System and Consensus X-rays Using Various Thresholds
Day 1
Interventions
