Additional Manufacturer Narrative
The returned valve was patent.It met the requirements for pressure-flow and pre-implantation testing.However, the valve did not meet the requirements for reflux testing.There was proteinaceous debris observed within the interior and exterior of the valve.Debris within the valve may hold pressure-flow controlling mechanisms open resulting in fluid reflux.The instructions for use (ifu) that accompany the device caution that ¿shunt obstruction may occur in any of the components of the shunt system.The system may become occluded internally due to tissue fragments, blood clots, tumor cell aggregates, bacterial colonization, or other debris.The returned valve did not meet the requirements for leak testing due to a tear noted in the top of the delta chamber.It is unknown how or when this damage occurred.The instructions for use that accompany the device caution that ¿care should be taken in handling the valves as silicone has a low cut and tear resistance.¿ it is also suggested that the valve be placed in a surgically created loose subgaleal pocket.This allows gentle placement of the valve and minimizes handling with surgical tools.A review of the manufacturing records showed no anomalies.All valves are 100% tested at the time of manufacture.
