It was reported that the procedure was to treat a heavily calcified lesion in distal superficial femoral artery.Resistance was met with the calcification during advancement of the 7.0x80mm armada 35 balloon catheter to the target lesion.The balloon was inflated 3 times at 15 atmospheres, and during the 3rd inflation the balloon ruptured.Resistance was felt during removal of the armada and the ruptured balloon could not be pulled into the introducer sheath.The sheath was coming out of the groin and the patients' groin started to bleed/leak.The patient was sent to surgery with the sheath, shaft, and balloon all still in.The shaft was cut during surgery and the separated portion was successfully removed.No additional information was provided.

(b)(4).Evaluation summary: visual inspections were performed on the returned device.The reported resistance met during advancement and removal could not be replicated in a testing environment as it was based on operational circumstances.The reported balloon rupture was confirmed.The instructions for use states: inflation in excess of the rated burst pressure (rbp) may cause the balloon to rupture.It is likely that inflating the balloon above the rbp contributed to the balloon rupture.The reported patient effects of hemorrhage, as listed in the armada 35, instructions for use is a known adverse event.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no other incidents from this lot.The investigation determined the reported difficulties, patient effects and treatment appears to be related to circumstances of the procedure.Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling.
