A territory manager reported an end user experienced an issue when using a guidewire from a bioflo midline 4f sl-20cm max barrier drape kit.After placing the guidewire, the wire unwound and frayed at the tip, and a 5mm piece actually broke off in the patient's soft tissue.A new tray was set up in order to continue to place the midline, at which time the guidewire was accidentally disposed of with the used kit.The new midline was placed in the patient's other arm.They reported that only a small piece of the tip had fractured off, approximately 5mm x 0.5mm according to the follow up imaging, so it was decided by the doctor that it posed the patient no risk and was left in the soft tissue.
