It was reported that the procedure was performed to treat a lesion in the moderately calcified, heavily tortuous right superficial femoral artery.A 6x120mm armada 35 percutaneous transluminal angioplasty (pta) catheter was advanced and felt resistance with the anatomy and an unspecified 6f introducer sheath.The balloon ruptured on the third inflation at 7 or 8 atmospheres.The pta catheter had difficulty being removed with an unspecified 6f introducer sheath, so the devices were removed together.The balloon separated in the anatomy, and the separated portion was surgically removed.The patient is fine.There was a clinically significant delay in the procedure.No additional information was provided.

A visual inspection was performed on the returned balloon catheter and the reported balloon rupture and balloon separation were confirmed.The reported difficulty to advance through the anatomy was unable to be replicated in a testing environment as it was based on operational circumstances.The reported difficulty to advance and retract through an introducer sheath was unable to be confirmed due to the returned condition of the device.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 reported from this lot.The device was prepped prior to use without any issue leak/ruptures noted, which would suggest that the device was not damaged prior to use.The investigation determined the reported/noted difficulties appear to be related to operational circumstances of the procedure.Based on the reported information, the balloon catheter encountered resistance during advancement with the moderately calcified, heavily tortuous and 6f introducer sheath.It is likely that during advancement the balloon outer surface became damaged and/or compromised resulting in the reported balloon rupture.Due to the balloon rupture, the balloon did not properly refold causing the difficulty to remove from the introducer sheath and anatomy.Manipulation against resistance during retraction ultimately resulted in the balloon, balloon marker and inner member separation freezing the device to the guide wire and subsequent noted damages to the balloon catheter.The reported treatment appears to be related to the case circumstances of the procedure as a separated section of the device was surgically removed causing significant delay in the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling; therefore, no corrective action is required.H6: health effect clinical code: 4582 removed.
