Additional narrative: the complaint device was not returned for evaluation.A root cause cannot be determined; however, one possible root cause is the failure mode results when main pusher rod is bent upwards; the failure mode is due to the interference of the bent pusher rod with the 2nd implant during deployment.This bent rod will push the 2nd implant and 1st implant from the needle, thus deploying both implants.Based on the information provided and the devices that were returned we cannot confirm this complaint.A batch record review has been conducted to determine if there were any internal processing issues which would have contributed to the nature of the product complaint.Our results indicate that this batch of product was processed without incident and therefore there is no internally assignable cause for the reported problem.Further, a review into the depuy synthes mitek complaints system revealed one similar complaint for this lot of devices that were released to distribution.At this point in time, no corrective action is required and no further action is warranted.However, depuy mitek will continue to track any related complaints within this device family as a means of monitoring the extent with which this complaint is observed in the field.(b)(4).Associated medwatch 1221934-2016-10272.
