Blank fields on this form indicate the information is unknown, unchanged or unavailable.Investigation ¿ evaluation an issue with a thal-quick chest tube set (rpn: c-tqts-1000, lot: 14513294) was reported by a representative from (b)(6) (france) on (b)(6) 2022.Difficult removal of the wire guide from the catheter was experienced after placement.The wire guide then unraveled.The patient reportedly experienced no adverse effects due to this occurrence.Reviews of the documentation, including the complaint history, device history record, instructions for use (ifu), manufacturing instructions, quality control procedures and specifications, as well as a visual inspection and dimensional verification of the returned device, were conducted during the investigation.The complaint device was returned in a used and damaged condition.The wire guide was unraveled along the shaft 40.5cm from the proximal end.The safety wire and mandril were both exposed.The distal weld and coils surrounding it remained intact.The solder joint between the safety wire and mandril likely broke during the procedure, resulting in the observed unraveling of the coil.Dimensional analysis confirmed that the device and components were manufactured to the correct specifications and tolerances.Additionally, a document-based investigation evaluation was performed.A review of the device master record (dmr) concluded that sufficient controls are in place to detect this failure mode prior to release.A review of the device history record (dhr) for lot 14513294, as well as wire guide subassembly lots ic14393411 and ic14413872, found no nonconformances that could have contributed to the reported failure.It should be noted that no other complaints were associated with the final product lot number.Cook also reviewed product labeling.Instructions for use (ifu) document c_t_thal_rev11 [thal-quick chest tube sets and trays] is packaged with this device.The product ifu states the following in consideration of the reported failure mode: instructions for use 5.When the appropriate drainage site has been identified, advance the soft ¿j¿ end of the wire guide through the needle and into the pleural space.(fig.1) note: the wire guide should pass through the needle and advance into the pleural space without resistance.Note: due to anatomical variations in chest wall thickness, insertion depth of introducer needle, wire guide and dilators will vary form patient to patient.8.While maintaining the wire guide position, dilate the tract and opening into the pleural space by advancing, in sequence small to large, the supplied dilators over the wire guide.Introduction into the pleural space is facilitated by rotating and advancing the dilators in line with the wire guide to prevent its kinking.(fig.2) 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.(fig.3) 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.How supplied upon removal from package, inspect the product to ensure no damage has occurred.The information provided upon review of the dmr, ifu, dhr, and returned device suggests that the device was not manufactured out of specification, and that there are no nonconforming devices in house or out in the field.Based on the information provided, examination of the returned product and the results of our investigation, it was concluded that a component failure unrelated to manufacturing or design deficiencies contributed to the event.It is possible that the wire guide was unwittingly damaged during use prior to attempted removal by either the needle, dilators and/or the chest tube assembly.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.
