The device was not returned for evaluation, and the lot number of the failed device could not be determined.Therefore, medline renewal does not have enough information to determine the root cause of the failure.The instructions for use warn the user that the tip of the device may break if excessive force is applied, and that the use of force to pass the needle through fibrous/calcified tissue, or striking bone, can cause needle breakage and patient injury.It is recommended to reposition the needle to pass through a different area.Although the device was not returned for evaluation, medline renewal is filing this medwatch report in an abundance of caution.(b)(4).
