Investigation ¿ evaluation: (b)(6) , in france, reported to cook that during a pneumothorax drainage procedure, the wire guide was noted to be ¿relaxed¿ when it was removed from the patient.The customer provided a photograph of an unraveled and elongated wire guide for the investigation (rpn: c-tqts-1000, lot: unknown).The wire guide was removed from the patient, and a new drain was placed.The patient did not experience any adverse effects or require any additional procedures due to this occurrence.Reviews of the documentation including the complaint history, instructions for use (ifu),quality control procedures of the device, as well as a visual inspection of a provided photo of the complaint device, were conducted during the investigation.The complaint device was not returned for evaluation; therefore, no physical examination could be conducted.However, a photograph provided by the facility showed the wire guide to be in an unraveled state.Additionally, a document-based investigation evaluation was performed.A review of the device master record (dmr) concluded that the product is 100% inspected during the manufacturing process for defects.Sales to the customer were reviewed and yielded six possible lot numbers for the complaint device (9110039, 9550142, 9676630, 13673397, 13917335 and 13956464).A review of the device history record (dhr) for these lot numbers found relevant nonconformances that could have contributed to the reported failure mode; however, nonconforming devices were scrapped per the 100% quality control inspection.Cook also reviewed product labeling.This product is supplied with an instructions for use (ifu) pamphlet c_t_thal_rev11.In the instructions for use section, it states: 9) with the wire guide still positioned within the pleural space, advance the chest tube inserter/chest tube assembly over the wire guide and into the pleural space.Note: if resistance is encountered during chest tube assembly insertion, determine the cause of resistance, and take necessary action to relieve resistance before proceeding.Note: it is important to advance the chest tube assembly into the pleural space in the same line as the wire guide.This will make introduction easier and avoid kinking of the wire guide.Note: the distal end of the chest tube inserter should not be advanced beyond the distal end of the wire guide.10) remove the wire guide and chest tube inserter, leaving the chest tube in place.(fig.4) in the how supplied section it states: upon removal from package, inspect the product to ensure no damage has occurred.Evidence provided by the device master record review, device history record reviews, and provided photo, suggests that the device was manufactured to specification.There is no evidence of nonconforming devices from the complaint lot in house or in the field.Based on the information provided and the results of our investigation, it was concluded that a component failure without design or manufacturing deficiency contributed to the reported event.The appropriate personnel have been notified.Per the risk assessment no further action is required.We will continue to monitor for similar complaints.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.
