Additional information was provided on 20sep2021.The access site was the right internal jugular vein.The right hepatic vein was accessed to puncture the liver.There were no anatomic difficulties in gaining access to the organ.A second needle was opened after the first one failed and exibited the same failure during the same procedure.The catheter shaft was shaved by the large colapinto needle.The "shear" was identified when attempting to remove the black inner sheath, it could not be removed smoothly.The transjugular approach was aborted after the failure.No force was exerted on the separated hub of the introducer.The equipment was reported to have been used per instructions for use (ifu), following the steps per ifu.

Investigation ¿ evaluation: (b)(6) hospital (singapore) informed cook that on 16jun2021, the black catheter in a liver access and biopsy set (rpn: labs-100-j, lot: 13099332) was shaved after being withdrawn through the guiding cannula.After the first failure, a second device was opened, and the failure occurred again.The transjugular approach was aborted after the two failures.It is reported that the patient did not suffer adverse effects due to this incident.Reviews of the documentation, including the complaint history, device history record, instructions for use (ifu), manufacturing instructions and quality control procedures, as well as a visual inspection, dimensional verification, and functional test of the returned device, were conducted during the investigation.Two used guiding cannulas were returned for evaluation.Hub separation in both black catheters was noted.Splits in the black catheters were noted as they exited the cannulas.Dimensional analysis confirmed that the devices 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 inspection activities are in place to identify this failure mode prior to distribution.A review of the device history record (dhr) for lot 13099332, sheath component lot ic13016199, as well as needle component and subassembly lots ic10343510, sa10278385 and sa10278386, found no nonconformances that could have contributed to the reported failure.It should be noted that there was an additional complaint associated with the final product lot number; however this complaint is from the same facility for the same procedure.The failures were found to be unrelated.Cook also reviewed product labeling.The product ifu, [t_labs_rev7] ¿liver access and biopsy set,¿ provides the following information to the user related to the reported failure mode: instructions for use: ¿3.-note: care should be taken to prevent damage to the straight catheter during removal through the metal stiffening cannula.Leaving a wire guide through the straight catheter during removal may aid in preventing catheter damage.¿ how supplied: ¿-upon removal from package, inspect the product to ensure no damage has occurred.¿ evidence gathered from reviews of the dmr, dhr, device failure analysis, and design history file, suggest that there is no indication the device was manufactured out of specification.There is no evidence of nonconforming material in house or 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 contributed 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.
