Pma/510(k) #: k163468.Device evaluation: 1 unit of evo-22-27-9-d lot# c1779450 involved in this complaint was 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 device related to this occurrence underwent a laboratory evaluation on the 09 dec 2021.On evaluation of the device the shuttle cap was observed to be broken and the polyimide was kinked.Handle was actuating fine for deployment and recapture but unable to deploy the stent.Handle was opened and the shuttle cap observed broken.Stent deployed manually without any issues.Lock wire removed without any issues.Stent intact.An additional complaint ((b)(4)) was opened to address broken shuttle cap found during lab evaluation.Document review: prior to distribution evo-22-27-9-d devices are subjected to a visual inspection and functional checks to ensure device integrity.A review of the manufacturing records for evo-22-27-9-d of lot number c1779450 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 c1779450.The instructions for use ifu0053 which accompanies this device instructs the user to "visually inspect with particular attention to kinks, bends and breaks.If abnormality is detected that would prohibit proper working condition, do not use." there is not sufficient evidence to suggest the user did not follow the ifu.Root cause review: a definitive root cause could not be determined as the circumstances of use cannot be replicated in the laboratory.As noted during the lab evaluation the handle was actuating fine for deployment and recapture but the polyimide was kinked and the shuttle cap was broken.As per engineering input "the fact that the user was able to partially deploy and recapture the stent confirms that shuttle cap was not completely broken and functioning." a possible root cause could be attributed to tortuous patient anatomy.It is possible that during deployment tortuous path may have kinked the polyimide.Summary: the customer¿s testimony could not be confirmed however the complaint is confirmed based on the failure verified in the investigation.The introducer tip was not broken however the polyimide connected to the tip was kinked.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.
