The stellarex catheter was returned intact within a 6f introducer sheath and the balloon protector sheath was pulled back near the strain relief.Visual inspection found a bunched balloon that had a proximal radial tear and would not allow the catheter to be removed from the introducer sheath.The mono lumen was stretched and both marker bands were present.Measurement of the balloon length met specification, which indicates there are no missing fragments.Per the ifu, embolism/device embolism is listed as a potential complication/adverse event of the procedure.
