Manufacturer Narrative

(b)(4).(b)(6).(b)(4).Pma/510(k) #p100022/s014.The zisv6-35-125-8-60-ptx device of lot number c1355860 involved in this complaint has not yet been returned for evaluation.With the information provided, a document based investigation was conducted.The customer was contacted to return the complaint device.The investigation will be updated once the device has been returned and evaluated.There is no evidence to suggest that this incident did not occur.Therefore, the complaint is confirmed based on customer testimony.Possible causes for this occurrence could include device handling.From customer testimony, it is known that the physician repeatedly flushed, wired and handled the device, before hearing the audible crack.This could have caused or contributed to the thumbwheel malfunctioning.However, as the device has yet to be returned, and the circumstances of use cannot be replicated in a laboratory environment, a definitive root cause cannot be determined.There is no evidence to suggest that the customer did not follow the instructions for use.Prior to distribution all zilver ptx devices are subject to visual inspection and functional checks to ensure device integrity.A review of the relevant manufacturing records revealed no discrepancies that could have contributed to this complaint.Upon review of complaints, this failure mode has not occurred previously with this 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 c1355860.It may be noted that the failure mode of "handle broken" has been provisionally assigned.The final failure mode will be confirmed following device return and evaluation.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.The procedure was completed with another device.Complaints of this nature will continue to be monitored for potential emerging trends.

Event Description

The wire went through the initial end hole, but it would not come out the back end hole of the catheter of the zilver stent.The facility indicated they repeatedly flushed the system, tried to put the wire back in, but they heard a audible crack.Also, the thumbwheel assembly started to spin around the catheter system.At this point , the facility stopped trying to prep the device and that's when they opened up a new one to complete this procedure.The second / new zilver that was opened to complete the procedure was a longer length because that's all they had left on their shelf.The above occurred during the prepping process away from the patient.
