Methods: the device was previously reported to be returning for an evaluation; however, it has subsequently been reported that the device will not be returned.Results: as the device and lot number were unavailable for analysis, no methods were performed.For this reason results cannot be obtained.The instructions for use (ifu) specifies the following: "warning: place catheter such that obstruction will not occur and catheter removal will not be impeded.Prior to final suturing, make sure catheter moves freely to ensure it¿s not caught in sutures.Assure that catheter is not in a vein or artery.Cautions: if resistance is encountered or catheter stretches, stop.Continued pulling could break the catheter.It¿s advisable to cover the site with warm compresses, and wait 30 to 60 minutes, and try again.The patient¿s body movements may relieve the catheter to allow easier removal.For additional information refer to the technical bulletin: tips for preventing in-situ catheter breakage with the on-q system.Do not cut or forcefully remove catheter.After removal, check distal end of catheter for black marking to ensure entire catheter was removed." conclusions: the device was not returned to halyard for evaluation, therefore we are unable to determine the cause for the reported event.A technical bulletin (mk-00021) tips for preventing in-situ catheter breakage was sent to the customer.Information from this incident has been included in our product complaint and mdr trend reporting systems.Trend information is used to identify the need for additional investigations.
