Based on the details of the complaint it was reported that a chest tube had disconnected from the stop-cock to the pigtail drain.The clinician double clamped the chest tube.The stop-cock and pigtail pulled apart at the connection site.It is not very clear on what actually happened during the use of the chest drain but appears as if the pigtail catheter of an unknown origin had been connected to a chest tube that was connected to the express ii single chest drainage system.The drain was not available for return and evaluation, nor was the catheters that were connected to the drain.The additional information that was provided stated that there was a possibility that patient movement most likely contributed to the dislodgement and separation of the pigtail catheter connection from the drain.A review of the device history records shows that this lot of express chest drains passed all quality and performance requirements and that no non-conformances were noted during the process of manufacturing.Additional samples of express chest drains were not pulled from inventory because the reported details stated in all likelihood that the patient movement caused the disconnection of the catheter from the drain and was not related to the functionality of the drain.Based on the details of the complaint and correspondence indicating that the connection was likely due to the patient movement the investigation could not conclude that the drain was defective and therefore cannot confirm the complaint.H3 other text: not available for return.
