Evaluation summary: post market vigilance (pmv) led an evaluation of four photos and one device.The first and second photos depict the cams on one of the jaw legs were disengaged from the drivers.The third and fourth photos depict unformed clips and a partially formed clip next to the jaws of the instrument with cams on one of the jaw legs disengaged from the drivers.The instrument was received partially fired with five clips remaining.Visual inspection of the instrument noted that one of the jaw legs was out of position.The cam on the jaw leg was not aligned with the driver.The tissue stop was disengaged.Functionally, the jaw leg was reset by aligning the cam with the driver.The instrument was then applied to test media.The remaining clips loaded into the jaws, formed properly, released from the jaws and remained securely attached to test media.The interlock engaged after all clips were dispensed to prevent the jaws from approximating.A review of the device history record indicates the product was released meeting all quality release specifications at the time of manufacture.Replication of the disengaged jaw cam condition may occur when one of the jaws legs gets forcefully pulled outward away from the center line of the shaft.The noted jaw cam disengagement impedes functionality of the jaws, possibly resulting in clip malformation and/or difficulty removing the instrument from a trocar.Replication of the disengaged tissue stop may occur when the distal end of the instrument is subjected to excessive manipulation.The root cause of the observed damage was misuse of the product which would have caused or contributed to the reported incident.If information is provided in the future, a supplemental report will be issued.
