Manufacturer Narrative

Pma/510(k) #: p100022/s014.Device evaluation: there are two complaint files related to this occurrence.For details of the second investigation please refer to (b)(4).The zisv6-35-125-7-80-ptx device of lot number c1607584 involved in this complaint was not available for evaluation.With the information provided, a document based investigation was conducted.Document review: prior to distribution zisv6-35-125-7-80-ptx 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.A review of the manufacturing records for zisv6-35-125-7-80-ptx of lot number c1607584 did not reveal any discrepancies that could have contributed to this complaint issue.The review of relevant manufacturing records, confirms the failure mode has or 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 c1607584.There is no evidence to suggest the user did not follow the instructions for use (ifu0118-5).Root cause review: as the device was not returned for evaluation and images of the procedure were not available for review, a definitive root cause could not be determined.A possible root cause could be attributed to the stent struts becoming caught on each other during deployment.This would have resulted in the stents not expanding fully and the requirement for the user to perform balloon angioplasty to fully expand the stents.Summary: the complaint is confirmed based on customer testimony.According to the initial reporter, the patient required balloon angioplasty to expand both stents.Complaints of this nature will continue to be monitored for potential emerging trends.
