Additional Manufacturer Narrative
Investigation: visual inspection: scratches on the outer housing of the valve were observed through the visual inspection.No significant deformations or damage were detected.Permeability test: a permeability test has indicated that the valve has a blockage.Adjustment test: the m.Blue valve was tested and is not adjustable throughout the normal range.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.Computer controlled test: to investigate the claim of under-drainage, the opening pressure is measured using a miethke computer controlled testing apparatus which simulates a cerebrospinal fluid flow.Because the valve is not permeable, a computer controlled test is not applicable.Internal inspection: after dismantling of the valve, significant deposits were found in m.Blue.Results: in advance, we would like to point out to you that the adjustment test and permeability test have already been carried out after the revision on clinic part.Based on our examination results, we can determine a blockage and non-adjustability at the valve at the time of our examination.This is likely due to the deposits observed inside the valves.As described in scientific literature, the problem encountered is one of the known, inevitable risks of hc-therapy by shunt implants.We can exclude a defect at the time of release.The valve met all specifications of the final inspection when released from christoph miethke (b)(4).No further regulatory actions are required from our point of view.
