(b)(4).The customer returned one s-l catheter for evaluation.Signs of use in the form of biological material and sutures were observed on the catheter body.Visual inspection confirmed the distal extension line was separated 13 mm from the luer hub.The separation point was rough and jagged.This is consistent with undue force being applied to the extension line.The extension line was separated 13 mm from the luer hub.The total length of the catheter measured 527 mm, which is within specifications of 500.1-550.9 mm per catheter graphic.The inner diameter of the distal extension line measured 0.058", which is within specifications of 0.055-0.059" per extrusion graphic.The outer diameter of the distal extension line measured 0.08490", which is within specifications of 0.084-0.088" per extrusion graphic.This indicates that the wall thickness is within specifications.The catheter was not able to be functionally tested due to the damage.A manual tug test confirmed the distal luer was secure to the extension line.A device history record review was performed, and no relevant findings were identified.The instructions for use provided with this kit warns the user, "do not apply excessive force in removing spring-wire guide or catheter.If withdrawal cannot be easily accomplished, a visual image should be obtained and further consultation requested.Do not use scissors to remove the dressing to minimize the risk of cutting the catheter.Do not suture directly to the outside diameter of the catheter to minimize the risk of cutting or damaging the catheter or impeding catheter flow.To minimize the risk of catheter breakage, do not exert excessive force while removing the catheter." the complaint of an extension line separated was confirmed by a complaint investigation on the returned sample.Visual inspection revealed the distal extension line was separated 13 mm from the luer hub.The separation point was rough and jagged, this is consistent with undue force being applied.A device history record review was performed, and no relevant findings were identified.Based on the sample returned and the customer description that the damage occurred during use, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend on complaints of this nature.
