It was reported that an 8x80mm armada 35 percutaneous transluminal angioplasty (pta) balloon ruptured.During withdrawal, the marker separated from the catheter in the subclavian artery.The marker then migrated to the pulmonary artery.A snare was attempted several times to retrieve the marker but was unsuccessful.The procedure was then complete and computed tomographic (ct) angiography was performed to evaluate the patient, which did not identify any pulmonary embolism.The patient was expected on (b)(6) 2019 for a follow up evaluation.There was no reported clinically significant delay in the procedure.No additional information was provided.User facility medwatch report received that states: "during an interventional radiology procedure, right arm fistulogram, the balloon catheter ruptured and while attempting to withdraw the catheter from the body, the market tip separated from the catheter in the subclavian artery.The catheter marker tip migrated to pulmonary artery.The dr attempted multiple times to snare the marker tip and was successful.The dr ended the case and send pt to ct for further evaluation.Fda safety report id#(b)(4).".

A visual inspection was performed on the returned device.The reported balloon rupture and separation were confirmed.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 incidents and/or complaints reported from this lot.There was no damage noted to the balloon catheter during the inspection prior to use which suggests a product quality issue with respect to manufacture, design or labeling did not contribute to the reported difficulties.Additionally, the device was prepped prior inflation of the balloon without any leak or ruptures noted, which would suggest that the device was not damaged prior to use.It should be noted that y the armada 35 / armada 35 instructions for use states: the device is intended for dilatation of lesions in the renal, iliac, femoral, popliteal, tibial, and peroneal arteries.In this case, use of the armada 35 in the wrong anatomy did not cause or contribute to the reported difficulties.The investigation determined the reported balloon rupture appears to be related to circumstances of the procedure.It is likely that during advancement the balloon became compromised and/or damaging against the anatomy or other devices used resulting in the balloon rupture and not allowing the balloon to properly refold and causing resistance during retraction.Manipulation and/or inadvertent mishandling of the device during retraction likely resulted in the reported/noted separations to the device and subsequent damages.The stretched inner member likely caused the balloon dilatation catheter (bdc) to become frozen or stuck on the guide wire.The reported patient effects of appear to be related to circumstances of the procedure as a snare was attempted several times to retrieve the marker but was unsuccessful.There is no indication of a product quality issue with respect to manufacture, design or labeling; therefore, no corrective action is required.Exemption number e2019001-permits numbering sequence to begin with 10000, to avoid duplication of report numbers due to process transition.There may be gaps in numbering for reports submitted during the transition period.Contact office first name, contact office last name, have been corrected.
