Additional Manufacturer Narrative
Cook ireland ltd (manufacturer) is submitting this report on behalf of cook medical incorporated (cmi)(importer).Exemption number: e2016031.Importer site contact and address: (b)(6).Cook medical incorporated (cmi) (b)(4).Importer site establishment registration number: (b)(4).Device evaluation: two zso-7-7 devices of lot number c1533813 involved in this complaint were returned for evaluation, with the original packaging.The packaging was open on receipt.With the information provided, a physical examination and document based investigation was conducted.Lab evaluation: the devices related to this occurrence underwent a laboratory evaluation on the (b)(6) 2019.A kink was observed on the 5th porthole at the tapered end of the stent of the first device.A 0.035¿ wire guide could not pass the kink on the first device.No defects were observed on the second returned device and a 0.035¿ wire guide was passed as expected.Document review: the zso-7-7 device of lot number c1533813.A review of qc lot #¿s 319534 and 322400 confirmed that this component was a ship to stock item and was accepted into cook ireland.Prior to distribution zso-7-7 devices are subjected to a visual inspection and functional checks to ensure device integrity.These inspections and functional checks are outlined in internal procedures in place at cirl.As per step 3 in final quality control, fqc0144 the manufacturing team member (mtm) is instructed to "inspect for debris in or on product, kinks".Additionally, in step 9 of fqc0144, the manufacturing team member (mtm) is instructed to ¿verify size of wire guide before each use.Insert wire guide into both ends of stent.¿ a review of the manufacturing records for zso-7-7 of lot number c1533813 did not reveal any discrepancies that could have contributed to this complaint issue.The review of relevant manufacturing records, confirms the failure mode has not previously occurred with the current lot number.Based on the information available to date, there is no evidence to suggest that there are any manufacturing issues associated with lot number c1533813.It should be noted that the instructions for use (ifu0045-6) states the following: ¿visually inspect with particular attention to kinks, bends and breaks.If any abnormality is detected that would prohibit proper working condition, do not use.¿ ¿care must be exercised when straightening the pigtail curls in order to avoid kinking or breaking the stent.¿ root cause review: a definitive root cause could not be determined as the circumstances of use cannot be replicated in the laboratory.A possible root cause could be attributed to the use of a non-recommended wire guide with the device.It may be noted the device label indicates a 0.035¿ wire guide for use with this device and all simulated use testing to date has been completed using a 0.035¿ wire guide.As the smaller diameter 0.025¿ wire guide occupies less space in the lumen of the pigtail stent it is likely that the extent of the curvature of the pigtail will be greater when a 0.025.As per additional information received the user used a 0.025" wire guide.Summary: complaint is confirmed as the failure was verified in the laboratory.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.Complaints of this nature will continue to be monitored for potential emerging trends.
