The following were reviewed as part of this investigation: patient severity, complaint and lot history review, applicable previous investigation(s), sample (if available), labeling, and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a guidewire stuck in an introducer needle is confirmed and was determined to be use related.One 0.035 in.J-tip guidewire in a plastic hoop and one 18 g introducer needle were returned for evaluation.An initial visual observation showed blood residue on the returned samples.About 1.7 cm of the guidewire was observed to be protruding from the distal tip of the introducer needle.The core wire was found to be broken during tactile evaluation of the guidewire.The guidewire was found to be stuck within the introducer needle.The guidewire was able to be pushed through the needle with considerable force.A microscopic observation of the introducer needle before and after the guidewire was removed revealed the bevel of the needle was damaged.A large amount of biological material was observed on the section of the guidewire that was within the cannula of introducer needle, which may have contributed to the guidewire becoming stuck as well as the break in the core wire.Normal movement of the guidewire is away from the sharpened bevel and will not damage the wire.If the guidewire direction is reversed, the guidewire is then pulled against the sharpened edge of the needle bevel and can cause shearing damage of the wire and/or cause the wire to become stuck within the needle.The product ifu cautions: ¿do not pull back guidewire over needle bevel as this may sever the end of the guidewire.The introducer needle must be removed first.Also, if unusual resistance is met during manipulation of the guidewire, discontinue the procedure and determine the cause of resistance before proceeding.Withdraw needle and guidewire if cause of resistance cannot be determined.¿ a lot history review (lhr) of redp4256 showed no other similar product complaint(s) from this lot number.
