The bipolar liner was returned for review with the split poly ring partially disassembled.Dimensional analysis determined that both the liner and split poly ring were separately conforming to print specifications.The split poly ring successfully mates with the liner and the device functions as intended; there are no nonconformances identified, therefore an investigation run by the manufacturing site is not necessary.The device was intended to be used as a treatment to a disease.It is possible that the ring's position had shifted during transit.The device was manufactured in february of 2014 and the event occurred 14 months later.The number of times it has been transported is unknown, however its distribution did include international transit which could have subjected it to movements and vibrations which caused the split poly rings to shift.No additional complaints have been received from this manufacturing lot.With the information provided, no failure is found.
