(b)(4).Device evaluation summary: post market vigilance (pmv) led an evaluation one endo gia adapter and one idrive ultra powered handle.This evaluation was based on a technical review of all data received from the site, a pmv review of manufacturing records, a pmv review of complaint trends, and an engineering evaluation of the returned device.Microscopic evaluation revealed 2 cracked solder joints in the adapter.During functional testing, the handle tested satisfactorily.The reported conditions were not replicated during testing.Disassembly of the device revealed a bowed switch affecting the switch activation height.The lockout slider block also exhibited damage consistent with improper loading of the device by the user.Visual testing of the returned product confirmed the reported condition due to the bowed switch and cracked solder joints.Inconsistent reload recognition can be caused by a malfunctioning switch as a result of compromised solder joints.The root cause of the observed condition was determined to be a result of a manufacturing activity and a product enhancement has been initiated to prevent recurrence of this condition.Should new information become available, the file will be re-opened and the investigation summary will be amended as appropriate.
