(b)(4).Upon completion of the investigation it was noted that the images were taken of the ¿as received¿ valve.The position of the cam when valve was received was 30 mmh2o.The valve was visually inspected: needle holes in the needle chamber were noted, and the proximal connector was slightly bent.The valve was hydrated.The valve was tested for programming with programmer 82-3126 with serial (b)(4), the valve passed the test.The valve was flushed, the valve failed the test an occlusion was noted.The valve could not be leak tested, due to the blockage.The valve could not be reflux tested due to the blockage.The siphon guard could not be tested due to the blockage.The valve was dried.The siphon guard was removed.The valve could not be pressure tested, due to the blockage.The valve was dismantled and was examined under microscope at appropriate magnification: biological debris was found on the spring, on the spring pillar, on the ruby ball, on the seat of the ruby ball, on the cam mechanism, and on the base plate.Review of the history device records confirmed the valve product code 82-3182, with lot cvkb3c conformed to the specifications when released to stock in 27th september 2016.Review of the history device records confirmed the bactiseal catheter product code 82-3072, with lot 128451, conformed to the specifications when released to stock in 4th april 2017.The root cause of the problem found during investigation is due to the biological debris found on the spring, on the spring pillar, on the ruby ball, on the seat of the ruby ball, on the cam mechanism, and on the base plate.The root cause for the slightly bent proximal connector is probably due to user error, this however could not be determined.No defects were note with the bactiseal catheter.Based on the results of this investigation no further action is required.Trends will be monitored for this and similar complaints.At the present time this complaint is closed.
