(b)(4) the customer submitted one photo for analysis.The image shows a connector assembly, compression fitting, and compression sleeve within a hemodialysis kit.No damage is visible to any components.The customer also returned one connector assembly for analysis.Signs of use were observed.Visual analysis revealed no defects or anomalies on the returned sample.Visual analysis of the compression cap and green compression sleeve was unable to be performed as they were not returned by the customer.The returned connector assembly was tested per the instructions for use (ifu) provided with this kit.The ifu instructs the user, "slide threaded compression cap over compression sleeve towards hub connection assembly with compression sleeve seated completely inside.Thread compression cap onto hub connection assembly firmly, but do not over tighten.There should be no threads visible on hub connection assembly." a lab inventory compression cap and sleeve were threaded onto the connector assembly hub with little to no resistance.Once fully tightened the connection was secure.A device history record review was performed, and no relevant findings were identified.The ifu provided with this kit warns the user, "green compression sleeve must be present when threading compression cap onto hub connection assembly.Failure to do so may result in air embolism, blood loss, or catheter separation.Ensure compression sleeve is securely positioned inside threaded compression cap.Avoid attempts to place compression sleeve onto hub connection assembly cannula and then apply threaded compression cap.Incomplete compression may occur causing catheter separation." the customer report of a damaged compression sleeve could not be confirmed through investigation of the returned sample.The customer returned one connector assembly for analysis.No obvious defects or anomalies were observed, and the connector assembly passed all relevant functional testing.A device history record review was performed, and no relevant findings were identified.Without the compression cap and green compression sleeve returned to evaluate, the complaint could not be confirmed, and the probable cause could not be determined from the available information.Teleflex will continue to monitor and trend for reports of this nature.
