As reported, during preparation for an endovascular transluminal angioplasty of the superficial femoral artery (sfa), an advance 18 lp low profile balloon catheter would not maintain negative pressure.The user reportedly flushed the device and then attached an unknown inflation device to the balloon port.While pulling negative pressure, air was pulled into the inflation device and the balloon would not maintain negative pressure.The complaint device did not make contact with the patient.A new balloon worked as intended with the same inflation device.There has been no report that the patient required any additional procedures or experienced any adverse effects due to this event.
