(b)(4).Post market vigilance (pmv) led an evaluation of one adapter opened by the account.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 evaluation of the returned device.Microscopic evaluation of the adapter revealed 4 cracked solder joints.The eeprom (electrically erasable programmable read only memory) was uploaded and indicated five (5) autoclave cycles for the adapter.Before a battery was inserted, the unload button on the adapter was depressed numerous times and displayed no hang-ups or sluggish returns.The isi pin location was checked and found to be at the center.The center rod orientation was checked and was found to be assembled properly.Since the clinical battery, handle, and reload were not returned, pmv representative devices were utilized for all functional testing.After a pmv battery was inserted, the adapter was inserted onto a pmv handle and calibrated without issue.All five white status lights illuminated indicating more than 15 surgeries remaining on the adapter.A pmv reload was inserted onto the adapter and the reload detect led did not illuminate, indicating that the software did not recognize the presence of a reload.The unload button on the adapter was depressed numerous times and displayed no hang-ups or sluggish returns.A pmv reload was inserted onto the adapter again, and the reload detect led did not illuminate, indicating that the software did not recognize the presence of a reload.The adapter was disassembled and positive contact was made with the switch.The reload detect led illuminated intermittently.A malfunctioning switch is the result of several variables including: improper solder operation at the vendor location, improper assembly of the sealed switch to the mma board at the vendor location, and/or improper soldering during assembly.Should new information become available, the file will be re-opened and the investigation summary will be amended as appropriate.
