It was reported, a patient (demographics unknown) was undergoing an unspecified procedure using an advance 18 lp low profile balloon catheter.Target treatment area was a left below the knee location.The balloon was inserted to the desired vessel, markers were visualized, and an unsuccessful attempt was made to inflate the complaint balloon.It was inflated to nominal pressure.Omeron contrast in a 50/50 mix with saline could be seen filling the proximal vessels.At this point the balloon was deflated and removed without the sheath.It was not ruptured but suspected of leaking at the proximal connection to the shaft.A new balloon was used to successfully complete the procedure.According to the complainant, a 6fr sheath(cook) and an unspecified inflation device were used with the complaint device.No blood was noted in the inflation device.Additionally, the patient's anatomy was severely calcified without tortuosity or angulation.The balloon was not inflated inside a stent.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.
