Device not available for evaluation and it was discarded by end user.Investigation conducted based on dhrs review; documentation shows there was no abnormality or nonconformance recorded during manufacturing process.Based on complaint or event description received from end user, the wire met a resistance then it was removed while the needle was still in the position and this is where the wire will be sheared off when retrieving the wire over the needle.Also, there were multiple insertion attempts with the wire while the needle was in position.Ifu indicate; do not withdraw the guidewire back into the cannula as this may result in separation of the guidewire.The introducer cannula should be removed first.If the guidewire must be withdrawn while needle is inserted, remove both the needle and the wire as a unit to prevent the needle from damaging or shearing of the guidewire.The cannula must be removed first.Possible root cause for this occurrence; end user did not follow ifu.

As received by manufacturer from end user/sales rep.The guidewire broke in the patient as it was being used, and the piece could not be retrieved.Using the 4fr micro[?]puncture kit, flexible tip wire was passed through the wire and met resistance.The wire was removed and the access needle angle was changed slightly without removing vein access and maintaining aspiration of venous blood.The flexible tip wire was passed again and met resistance.It was easily removed, but on examination and fluoroscopy it was noted that the tip had sheared off.Multiple fluoroscopic images demonstrated a fixed wire tip in the location medial to the subclavian or internal jugular veins.
