Additional Manufacturer Narrative
Pma/510(k) #: p100022/s026.Device evaluation the zisv6-35-125-7-140-ptx device of lot number c1557555 involved in this complaint was implanted in the patient, and was not available for evaluation.With the information provided, a document based investigation was conducted.Document review prior to distribution zisv6-35-125-7-140-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 zisv6-35-125-7-140-ptx of lot number c1557555 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 c1557555.It should be noted that the instructions for use (ifu0118-4) instructs the user to ¿ensure the distal end of the stability sheath is inside the access sheath.¿ there is evidence to suggest that the instructions for use were not followed.Image review images were provided to support the complaint investigation.They were reviewed through cook research inc.(cri) and the following comments were provided by the independent reviewer.Impression the zisv6-35-125-7-140-ptx was first implanted concertinaed, then stretched, and finally normally.Because of the short sheath, antegrade access, and proximal sfa location, the stability sheath would have been outside the access sheath.Upon initial deployment, deployment sheath retraction would have advanced the stent.This explains the concertinaed distal stent and impression that the delivery system was stuck in the access sheath.With the application of countering traction, the mid stent was stretched.The final segment deployed with balanced traction.Root cause review a definitive root cause could not be determined from the available information.As per the imaging review a possible root cause could be attributed to the distal end of the stability sheath being outside of the access sheath during deployment and the attempt by the user to counteract the traction during deployment.Summary complaint is confirmed as the failure was verified in the image(s).According to the initial reporter, an additional stent was placed two hours after the zilver ptx stent became stretched.Complaints of this nature will continue to be monitored for potential emerging trends.
