Submit date: 04/29/2016.The device history record (dhr) was reviewed and no deviations related to this failure mode were found.There are not non-conformances related to the reported issue for the reported lot.The product sample was returned for investigation.The sample consisted of one mahurkar catheter that presented signs of use (remains of blood).A visual inspection was performed and it was observed that the red adapter had a crack on the thread pitch area at 180 degrees and it had cavity #5.Additionally, the adapters did not present marks that could indicate the use of some instrument.Based on the available information and the result of the dhr review that showed no deviations, it can be concluded that product was manufactured according to specifications and it functioned as intended for an undetermined amount of time; therefore it can be concluded that the adapter was more likely damaged during use.The most probable root cause can occur during use.According to the instructions for use adapter over tightening may cause leaking.The reported condition is being addressed by a corrective and preventative action (capa).No additional actions are required.It must be noted that in-process controls such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection and visual acceptance sampling are in place to prevent nonconforming product from leaving the manufacturing operations.This complaint will be used for tracking and trending purposes.
