Additional Manufacturer Narrative
The hakim valve (id 823112) was returned for evaluation.Device history record (dhr) - the product code 82-3112 with lot 3285931, conformed to the specifications when released to stock.Failure analysis - the valve was visually inspected; a cut/tear in the silicone housing at the proximal end was noted.The position of the cam when valve was received was 30mmh2o.The valve was hydrated.The valve was leak and leaked from the cut/tear in the silicone housing.The valve passed the test for programming, occlusion, reflux and pressure.No root cause could be determined as the technician could not confirm any occlusions with the valve at the time of investigation.The root cause for the pressure issue noted during the investigation is due to the cut/tear in the silicone housing.The root cause for the cut/tear in the silicone housing is probably due to a sharp or pointed object coming into contact with the silicone, as noted in the "ifu" silicone has a low cut/tear resistance.The possible root cause for the ¿valve obstruction was suspected¿ issue reported by the customer, could be due the cut/tear in the silicone housing near the proximal end.
