Product complaint # (b)(4).The complaint device was received and evaluated.Visual observations revealed that the upper jaw of the expressew gun was bent slightly towards one side contributing to jaw failure preventing it from closing completely.This complaint can be confirmed.Clamping excessive tissue between the jaws combined with repetitive twisting action exerts excess side load on the upper jaw deforming it off from its shape.This failure can be attributed to user technique.A dhr review has been conducted on this manufacturing lot and the results indicate that this batch of product was processed without any incident and therefore there is no internally assignable cause for the reported problem.Further, a review into the depuy synthes mitek complaints system revealed no other complaints of any type for this lot of devices that were released to distribution.At this point in time, no further action is warranted.However, depuy synthes 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).
