Manufacturer Narrative

Investigation: visual inspection: during the investigation, signs on the outer housing of the valve, but no significant deformations or damage was determined.Permeability test: a permeability test has shown that the valve is permeable.Computer controlled test: the results show that the valve operates within the accepted tolerances in the horizontal position.Adjustment test: the progav 2.0 was tested and is not adjustable.Braking force and brake function test: the brake functionality test has shown that the brake function is operational; however, the braking force cannot be measured due to the non-adjustability of the valve.Internal inspection : after dismantling of the valve, deposits were found in progav 2.0.Result : based on our investigation results, we can determine adjustment difficulties in the valve.The determined deposits can be named as the cause for the adjustment difficulties.Proteins in the cerebrospinal fluid can influence the function temporarily and are known side effects in hydrocephalus therapy.We can exclude a defect at the time of release.The valve met all specifications of the final inspection when released from christoph miethke gmbh & co.Kg.
