As reported, after releasing the stent of a 4mm x 18mm palmaz blue on aviator plus stent delivery system (sds) to treat vertebral artery stenosis, the balloon was unable to be deflated.As a result, the delivery system was intentionally cut, and the balloon was deflated with a syringe.The entire system was then withdrawn from the patient and the procedure was completed.The stent remained implanted and did not migrate as a result of the deflation difficulty.The device was stored and prepped per the instructions for use (ifu) and there were no difficulties removing any of the sterile packaging components.The lesion had moderate calcification, mild tortuosity, and a 75% stenosis.A non-cordis balloon catheter was used to pre-dilate the lesion.The aviator plus sds was not kinked at any time during this procedure.The device will be returned for evaluation.
