It was reported that the procedure was to treat an unknown carotid artery.The emboshield nav6 embolic protection system (eps) was advanced to the distal end of the stenosis and it was decided by the physician to use a 5x30x135 viatrac 14 plus peripheral dilatation catheter as there was no other suitable balloon to choose during the procedure.The viatrac ruptured at 14 atmospheres and half of the balloon was withdrawn from the anatomy; however, the other half remained on the unspecified guide wire.The balloon left on the guide wire was attempted to be removed with the guiding catheter, but it would not enter the guiding catheter.A separate sheath was advanced in attempt to snare the balloon; however, was unsuccessful.Therefore, the filter and the balloon were removed together with the eps barewire.Another same size viatrac and nav6 were used to successfully complete the procedure.There was no adverse patient sequela and no clinically significant delay.No additional information was provided.

A visual inspection was performed on the returned device.The reported material separation was confirmed.The reported material rupture and difficult to remove could not be tested due to the condition of the returned 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 incidents.The investigation determined the reported difficulties and subsequent treatment appears to be related to the operational circumstances of the procedure.It should be noted that the pdc, viatrac 14 plus, global ce, instructions for use (ifu) states: the viatrac 14 plus peripheral dilatation catheter is intended to dilate stenosis in the peripheral arteries (iliac, femoral, ilio-femoral, popliteal, infra popliteal, renal arteries), and for the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae.It is unknown if the ifu deviation contributed to the reported event.There is no indication of a product quality issue with respect to manufacture, design or labeling.D4: lot number was updated from 1042162 to 1033161.D4: expiration date was updated from 3/31/2023 to 2/28/2023.
