Crosstex (sps) recently received a complaint stating that us906 indicator dots were not transitioning to a darker color post sterilization.Suspect product was returned to crosstex for further testing during the investigation of the reported failure mode.The lot numbers provided, 580031-01 and 582691-01, are not recognized as issued by crosstex.Since the lot numbers are reassigned outside of crosstex, we are unable to perform a batch record review.Returned product was subjected to a standard steam sterilization cycle at 270 degrees for four (4) minutes.Two (2) surgical containers consisting of thirty (30) orange locks each were used in an attempt to replicate the results reported for this failure mode.Upon review, it has been determined that all dots tested for both respective lots have transitioned as intended.Since the results could not be replicated, the complaint cannot be confirmed.This issue has been logged and will be monitored for recurrence.Should you experience additional complaints in relation to this failure mode, or should a lot number become available, this complaint will be re-evaluated.Note: a retrospective review of potential serious injury complaints was performed.This mdr was identified as a reportable malfunction as a result and filed as part of the review activities.
