It was reported that the patient underwent a peripheral procedure to treat in-stent restenosis of an unspecified stent implanted in the right superficial femoral artery.A steelcore guide wire was advanced to the target lesion.A 2.0 laser was advanced and debulked the restenosis.An attempt was made to load the 5.0 x 80 mm armada dilatation catheter onto the guide wire; however, it became stuck.Attempts were made to remove the armada and the armada dilatation catheter separated outside the patient anatomy.The guide wire was in the patient anatomy, but the armada had not yet entered the anatomy.The steelcore guide wire and armada were removed from the patient anatomy as a single unit.A spartacore guide wire was then used with a new armada dilatation catheter without issue.There was no adverse patient effect and no clinically significant delay.No additional information was provided.
