It was reported, an (b)(6) patient (gender unknown) was undergoing an intervention of the superficial femoral artery utilizing a advance 35 lp low profile balloon catheter.The balloon burst circumferentially upon initial inflation in the heavily calcified lesion below nominal pressure.An inflation device was used.The balloon was inflated to 4 atmospheres (atm) once for 3 to 5 seconds.Omnipaque contrast in a 50/50 mixture with saline was used for the inflation.After bursting, the balloon was deflated and removed through a sheath.The lesion was described as 90 to 95 per cent occluded.There was no vessel angulation or tortuosity.Another balloon was used to complete the procedure successfully.A section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.
