It was reported that the procedure was to treat a moderately calcified, moderately tortuous lesion in the superficial femoral artery (sfa).A command 18 guide wire (gw) was placed across the lesion and a 5.5x200mm armada 18 balloon dilatation catheter (bdc) was advanced to the target lesion without issue.An attempt was made to inflate the balloon to nominal pressure; however, the balloon did not fully inflate, and a leak was noted in the hub of the device.The bdc was removed, and another armada 18 was used to successfully complete the procedure.There was no adverse patient effect and no clinically significant delay in the procedure.No additional information was provided.

The device was returned for investigation.The inflation problem and leak were confirmed.Additionally, the inner member was noted to be torn.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 of the reported lot revealed no indication of a lot specific issue.The investigation determined that the reported inflation issue and leak was due to damage noted to the inner member.Based on the evaluation of the returned unit and scanning electron microscopy (sem) analysis, the inner member damage may be attributed to mechanical damage and may suggest that an object was inserted into the inflation port; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
