The complaint was received and forwarded on to the manufacturing facility for investigation.The actual sample was not available for evaluation.It is vital to the investigation that the actual sample be available for examination and testing.The incoming inspection record for the raw material used to extrude the tubing was reviewed and certificate of analysis (coa) indicates that all test results were within specification limits, including tensile and tear tests.The non-conformance report (ncr) data since february 2017 to present was reviewed and no issues that could be related to the condition reported were found.Drain tubing were extruded within approved parameters and in accordance to specifications.The minimum tensile strength specification for the tubing is 750 psi.Device history record (dhr) of this tubing demonstrated tensile strength results of a minimum of 835 psi in testing performed.The minimum pull test specification for this drain is 3.0 lb.Dhr demonstrated pull test results of a minimum of 4.1 lb in the perforated area in quality testing performed.The dhr for the finished good was reviewed and no incident was documented that could have caused this type of non-conformance.This is the first incident reported for this lot due to broken drain.Historical trending was done.A root cause could not be determined.It is recommended to strictly follow the instructions provided in the instruction for use data included with the product to ensure drains are properly used.According to the instructions for use (ifu).¿drains or tubing should not be handled with any instruments.This can lead to tearing, warping, or weakening and subsequent breakage of the drain.To facilitate removal of the drain, the drain and tubing portions should not be curled, pinched, over-stretched or sutured; either internally or externally.Do not suture the drain(s).Drains should be placed and removed carefully by hand only with a slow, steady pressure.Excessive force may result in breakage.During placement and removal of the drain, do not nick, cut, tear or otherwise damage the drain as this may lead to breakage.Leaving the drain implanted for any period of time which allows for tissue ingrowth around the drain and into the holes, may cause breakage on removal.¿ we will continue to monitor trends and utilize this information as part of our continuous improvement.
