The system was used for treatment.This case is reportable as a mdr due to the reportable malfunction photoactivation module leak.Since this reportable malfunction is only associated with the kit, this mdr will only be against the kit.A batch record review for kit lot h352 was conducted.There were no non-conformances associated with this lot.This lot met all release requirements.A review of kit lot h352 for the reported issue shows no trends.Trends were reviewed for complaint category, photoactivation module leak.No trends were detected for this complaint category.Photographs of the complaint kit were returned for evaluation.Examination of the provided photographs verify cracks in the photoactivation module and a leak coming from the plate.A known cause for cracks in the photoactivation module is due to excessive solvent used during manufacturing.The solvent can cause damage to the photoactivation plate if too much solvent is used and left to set within the plate.It appears the excess solvent is from the bond that joins the black stripe tubing to the port on the photoactivation plate.Operators are to blot off the excessive solvent from the tubing before bonding it to the port and also preventing the solvent from dripping onto the plate during the plate assembly.The root cause of the cracks in the photoactivation plate is due to excessive solvent during the tube bonding process by the manufacturing operator.Retraining has been completed for the affected operators to reinforce proper tube bonding instructions.No further action is required at this time.This investigation is now complete.(b)(4).
