Manufacturer Narrative

The device, used in treatment, was returned for evaluation.A visual inspection of the returned device confirm the stated failure.There is rust on the laser marking of the device.The device exhibits signs of significant wear/ usage.A material check was performed and it is suspected that the laser marking is the root cause of the discoloration on the genesis calipers.It is suspected that the discoloration may be rust.A medical investigation was conducted and confirms based on the information provided, the definitive root cause of the rust could not be determined, as the provided ¿photo did not confirm the stated failure¿ per the visual product evaluation.The patient impact beyond the reported 45-minutes extension under anesthesia could not be determined; although, reportedly the procedure was completed ¿without and problems¿ and the events resulted in ¿no serious injury¿.No further medical assessment can be rendered at this time.Should additional clinical documentation become available in the future, the clinical/medical task may be re-evaluated.This issue is being addressed through our internal nonconformance process.This device is a reusable instrument that can be exposed to numerous surgeries; damage from repeated use can occur.Expected wear/tear is likely the probable cause of the reported event.We recommend that all reusable instruments be routinely inspected for wear and damage and replaced as necessary.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.Based on this investigation, corrective and preventive action is indicated to mitigate future recurrence of similar events.Should additional information be received, the complaints will be reopened.No further investigation is warranted for these complaints; however we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
