The customer sample was received for investigation.Visual examination of the returned sample showed that it is 1.09 inches in length portion of jackson-pratt silicone round drain 10fr.Visual inspection revealed that the silicone tubing broke off at perforated tubing section.Microscopic examination revealed wavy/jagged edge at the tubing fracture site and no distortion and/or tears in the adjacent portion drain, which suggests that the drain was not stretched (elongated) to failure.The characteristics of the fractured area and the absence of any tubing distortion are similar to those failures, which are caused by puncture by a sharp instrument on the tubing surface.As no lot number was provided, we were unable to trace the device history record, quality testing performed and corresponding results.An analysis of the complaint data since nov.2015 to present demonstrates that this is the first time that this type of issue is reported from this catalog, although (b)(4) incidents for the same condition from other catalogs were reported.The ncr data was also reviewed for the same time period and no issue that could be related to the condition reported were found.It is highly recommended that lot number are documented in patient medical record as reference for further investigation. the most probable root cause was identified as misuse by the customer since the wavy/jagged edge condition observed at the fracture area suggests that an instrument was used to handle the product which may have damage the product thus leading to tubing breakage.It is also 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.¿.
