Investigation ¿ evaluation: it was reported by a representative of (b)(6) hospital (usa) that an ultrathane mac-loc locking loop multipurpose drainage catheter (rpn ult10.2-38-25-p-6s-clm-rh; lot#: 14409357) leaked.After the device was placed in the patient¿s kidney, an air leak was discovered.An issue with the locking mechanism was assumed.As a result, the patient required an additional procedure to remove and replace the device.No other adverse effects were reported for this incident.Reviews of the complaint history, device history record (dhr), instructions for use (ifu), manufacturing instructions, and quality control procedures, as well as a visual inspection and functional test of the returned device, were conducted during the investigation.One device was received in used condition.The investigation confirmed there was one thread showing between the white cap / mac-loc adapter connection site, passing the required gap gauge requirement.During the initial investigation, a visual examination into the lumen of the mac-loc adaptor discovered a fold in the flare, resulting in the i.D.Of the mac-loc becoming partially obstructed.During leak testing, with the lever of the mac-loc adaptor in a down-ward position (locked), fluid was confirmed to be escaping at the white connecting cap and mac-loc adaptor site.After disassembling of the mac loc adaptor from the white connecting cap, the flare was discovered to be folded inward and torn.Based on the investigation results, it was determined the device was manufactured out of specification.Additionally, document-based investigation evaluation was performed.A review of the device master record (dmr) concluded sufficient inspection activities are in place to identify this failure mode prior to distribution.Cook also reviewed the device history record (dhr).The dhr for lot 14409357 found one possible relevant non-conformance for "folded flare".This device was scrapped prior to further manufacturing process.There were no additional complaints on this lot.An expanded search was conducted and all lots manufactured by the same flaring operator and proximal assembly operator were reviewed.Six total complaints for leakage were identified and the corresponding lots were placed on stop ship.The information provided upon review of the returned devices suggests that the device was manufactured out of specification.Review of the dhr suggests that there are additional nonconforming devices in the field but not in house.Containment was performed on related lots.Cook also reviewed the product labeling for the complaint device.The instructions for use (ifu) [ t_multi_rev5, multipurpose drainage catheter] states the following.Precautions: patients with indwelling drainage catheters should be evaluated routinely to ensure continuous function of the catheter.How supplied: upon removal from package, inspect the product to ensure no damage has occurred.Based on the information provided, inspection of the returned device, and the results of the investigation, it was determined the flare was manufactured out of specification.The cause of this event is manufacturing deficiency.The appropriate responsible manufacturing department was issued a defect awareness training.The appropriate personnel have been notified.Cook will continue to monitor for similar complaints.Per the 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.
