It was reported that the procedure was to treat a lesion in the superficial femoral artery (sfa).The 6.0x100mm armada 18 balloon catheter was advanced to post dilate an absolute pro stent.Prior to inflating the armada bdc, it was observed that the proximal balloon marker did not align with the length of the implanted stent.When the armada bdc was inflated, the balloon shoulders were confirmed to be well within the stent, but the proximal marker did not align with the proximal balloon shoulder.The same balloon was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
