The device history record (dhr) review was not performed for any of the 5 returned devices.The production trace lot numbers were not reported and are unknown.The batteries list an expiration date of mar, 2016.Therefore, the batteries would have been delivered and placed into inventory at zimmer surgical in mar, 2010.Due to the severity of the corrosion the reported event is considered an out of the box event.Five units of the 00-5150-475-00 pulsavac plus were returned on 18 jun, 2015.All the devices were shipped loose inside a zip lock plastic bag.Visual inspection noted no obvious damage with the devices and the battery packs were not deformed.Visually the devices did display heavy wear and tear and dirt.Though this may have occurred in transit.Two of the devices were returned with the trigger depressed to engage the high speed mode and one device was returned with the trigger depressed in the low speed mode.All five devices did not function in the high speed or low speed mode when tested on 18 jun, 2015.Opening the battery packs it was discovered that all of the battery terminals and batteries had rust and corrosion.In two battery cases there was one battery that split open.In two battery cases there were two batteries that split open and in one battery case there were four batteries that had split open.Note, no anode expulsion was discovered.The corrosion on the terminals was extensive and could not be cleaned for retesting.All intact batteries in all of the devices were completely exhausted.The customers reported event that all five devices did not function.Additionally, it was reported that this same event had been experienced previously.Incoming inspection and functional test confirmed the customers reported event.The cause for the product failure is most likely due to the rust and corrosion on the battery terminal and probably caused the leakage from the batteries.The most likely cause for the battery corrosion is probably environmental conditions in storage or in transit.Recommended actions: with the initiation of the capa, no additional internal zimmer actions are warranted at this time.
