It was reported that the procedure was to treat a lesion in the left common femoral artery (lcfa) with heavy calcification.A 5fr sheath was used and the 6.0x150mm armada 35 balloon dilatation catheter (bdc) was advanced to the target lesion and the balloon was inflated; however, the balloon ruptured at 14 atmospheres during the first inflation.Therefore, the bdc was removed from the patient and resistance was noted with the sheath due the balloon not being fully deflated and only the proximal half of the bdc was removed.The distal half of the balloon, including the distal marker remain trapped in the superficial femoral artery (sfa).Bypass surgery was performed due to the balloon fragment lodged in the sfa.The patient is reportedly remaining hospitalized for several additional days.Prior to use the bdc was not prepped (air aspiration) outside the anatomy.No additional information was provided.

The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.It was reported that the device was not prepared (air aspiration) outside the anatomy.It should be noted that the percutaneous transluminal angioplasty (pta) armada 35 / armada 35 ll, global, instruction for use (ifu) indicates to perform the steps to remove all air and verify the integrity of the pta catheter.Leave the catheter under negative pressure until the balloon is at the target lesion site.Then the device can be introduced the device into the vascular system.In this case, it is unknown if the violation of the ifu caused or contributed to the reported complaint.The investigation determined the reported balloon rupture, deflation issue, difficulty removing the device from the introducer sheath, separation, foreign body in patient, surgical intervention and hospitalization appear to be related to operational context.Balloon material ruptures can be affected by numerous factors including, but not limited to, balloon damage during processing of the balloon material, materials, inflation technique, and interactions with other devices or lesion calcification.In this case, it is likely that the balloon rupture occurred, during inflation, due to interaction with the heavily calcified anatomy and subsequently the balloon did not fully deflate.In addition, the difficulty reported during removal and separation of the balloon were likely the result of the ruptured balloon material catching on the introducer sheath during removal.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.B2: outcomes attributed to ae - disability or permanent damage added.

Visual inspection was performed on the returned device.The reported balloon rupture and separation were confirmed.The reported deflation issue and difficulty removing the device could not be replicated in a testing environment due to the condition of the returned device.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.D9- device available for evaluation updated from ¿no¿ to ¿yes¿.H6- type of investigation code 4115 was removed.
