Investigation ¿ evaluation: a review of the complaint history, device history record, documentation, instructions for use (ifu), manufacturing instructions, drawings, specifications, and quality control data was conducted during the investigation.In addition, visual inspection and functional testing of unused product was completed.The complaint device was not returned, however, six unused/unopened devices from the same lot were returned and underwent functional testing and visual inspection.One set was opened, and there were no visible flaws in the chiba needle or the wire guide.The wire guide was advanced through the chiba needle then withdrawn.The wire engaged with the needle and jammed.For investigator safety, the wire was not pulled until breakage occurred.The wire was returned to the set, and the needle was discarded with sharps.The failure was not duplicated; however, with additional force, the wire may have experienced failure to breakage, elongation, and/or separation.The wire guide is shipped with an information label which illustrates; "withdrawal or manipulation of distal spring coil portion of wire guide through needle tip may result in breakage and/or damage." the ifu states within the precautions that "the product is intended for use by health care practitioners trained and experienced in proper positioning of catheters in the central venous system using percutaneous entry (seldinger) technique.Standard technique for placement of vascular access sheaths, angiographic catheters and wire guides should be employed." wire guides should not be withdrawn through any needle, but rather, the wire inserted through the needle then the needle removed over the wire while the wire remains in place.Furthermore, these steps are explicitly detailed within the instructions section of the ifu.Review of the device history record shows one nonconformance within the manufacturing department, which was identified as "short coil".This noted nonconformance was discarded prior to further processing.It should be noted there were no other reported complaints for this lot number.Based on the provided information and evaluation of returned (unused) devices, the root cause is product use / handling-related; separation of the wire guide was caused by withdrawal though the needle, which is a deviation from the ifu.While the initial damage to the wire guide was likely related to patient condition/anatomy (wire guide damage upon advancing through hematoma), it is likely that the eventual separation of the wire guide was caused by withdrawal through the needle, which is deviation from the ifu.Per the quality engineering risk assessment, no further action is required.We will notify the appropriate personnel and continue to monitor for similar complaints.
