It was reported the procedure was to treat a lesion in the right superficial femoral artery (sfa).An armada 18 was advanced to the lesion without resistance and the balloon was inflated without issues.However, the balloon was slow to deflate; it could visibly be seen under fluoroscopy, approximately 35 - 40 seconds it took the balloon to deflate.Once the balloon was deflated, the device was removed from the patient anatomy.An attempt was made to re-use the armada 18 for post-dilatation, but the balloon could not be inserted into the 6 fr sheath.Negative pressure was pulled and held, but the armada 18 balloon could not go through the sheath and then the balloon severely accordioned and crumpled up.The armada 18 was changed to a 5.5 x 60 mm armada 18 to complete the procedure successfully.The patient was fine.There was no adverse patient effect and no clinically significant delay in the procedure.No additional information was provided.
