The device involved in this incident was not returned for evaluation.Without an evaluation of the device involved we are unable to determine the cause or factors that may have contributed to this event.During validation of this device family testing was performed to assure that the separation force of the lumen to adaptor joint meets iso standard.The report stated that the doctor "did not visually check whether it was securely connected, because he connected the catheter with the compression ring attached to the stainless steel cannula part of the extension adapter." it appears that the device may not have been properly assembled leading to the extension separating from the lumen.
