Investigation - evaluation: (b)(6) health system (united states) informed cook on 13nov2020 that the hub on a ult10.2-38-25-p-3s-ucd-hc (ultrathane intro-tip design curved universal drainage catheter) from lot 13006135 separated after placement.The device had been successfully placed as a chest tube, and the failure was noticed after it was placed.The device was removed and another device from the same lot was placed in a separate procedure.The second device separated during the procedure and is captured under mdr ref.# 1820334-2020-02319.A third device was placed to successfully complete the procedure.A review of the complaint history, device history record (dhr), instructions for use (ifu), manufacturing instructions (mi), and quality control, as well as a visual inspection and dimensional verification of the returned device, was conducted during the investigation.One ult catheter tube without the hub was returned to cook for evaluation.Upon visual inspection, it was noted that the catheter had previously been cut below the flare.A hemostat mark was noted below the flare.The catheter tubing outer diameter was measured and found to within manufacturing tolerance.Cook has concluded that the device was manufactured to specification.Additionally, a document-based investigation evaluation was performed.A review of the device master record (dmr) concluded that sufficient inspection activities are in place to identify this failure mode prior to distribution.A review of the design history file (dhf) showed that this device is both safe and effective for its intended use.A review of the dhr for the reported complaint device lot 13006135 revealed no related non-conformances.A database search identified one additional event associated with the reported device lot.The additional identified event was reported by the same customer for a separation failure mode.Given this information, cook has concluded that there is no evidence suggesting that nonconforming product exists either in house or in field.Cook also reviewed product labeling.The device is supplied with instructions for use [ifu t_multi_rev5], which provides the following in relation to the reported failure mode: ¿patients with indwelling drainage catheters should be evaluated routinely to ensure continuous function of the catheter.¿ based on the information provided, inspection of the returned product, and the results of the investigation, a definitive root cause for this event has been traced to component failure unrelated to a deficiency in manufacturing/device design.The appropriate personnel have been notified.Cook will continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
