(b)(4).No samples were received for further evaluation.Multiple attempts to obtain samples, were not successful.Process cards show no abnormalities.Trend analysis: complaint trending from year 2014 to aug 2016 for similar defect of failure clip function of introcan were analysed.Complaint occurrence for justified and not judgeable complaint case was calculated as below.The complaint analysis showed decreasing trend from year 2014 to 2016 from 0.24 ppm to 0.11 ppm.All the justified cases were investigated to the extent possible based on availability of information provided.No justified complaint were reported after ca implemented.Review on production process flow as below, cam & ecm machine has online vision system to conduct 100% checking on relevant critical dimension of cannula including crimp width, crimp length, clip dimension and clip position.All the defective parts will be automatically rejected by machine.The in-line test equipment is subject of a frequent calibration and a regular verification related to its proper function.Herewith potential malfunctions of the systems would be detected in-time and would be mitigated asap.Beside the automated 100% in-line test equipment independent in-process quality controls and final controls on a random sample basis will be conducted by different teams on a regular basis within the production process.Here with a systematic product defect would be detected.Final control result for complaint batch: clip function test.Clip function specification: the needle clip must be blocked and the needle tip must not puncture through the glove.The complaint batch passed clip function test and showed no abnormalities.For clip fail to engage, the defects has been thoroughly investigated and a corrective action has been taken accordingly.The reported complaint batch was manufactured before the ca implemented.Hence, similar corrective action is applicable for this defect.Dhr history record review showed no deviation at in-process and final control inspection and the complaint batch pass clip function test.The actual sample involved in the event was not available for evaluation.Cause could not be determined.The complaint is only taken to the knowledge and filed for statistical purpose.However, if the sample and/or any additional information becomes available the complaint will be re-opened.
