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.Based on the information provided, a conclusive cause for the reported difficulties could not be determined.It may be possible that the absolute pro stent was narrowed in the mid area or the armada 35 balloon was inflated to a diameter larger than that the absolute pro stent diameter resulting in the stent fracture; 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.The armada balloon dilatation catheter referenced is filed under a separate medwatch report number.

It was reported the procedure was to treat an arteriovenous (av) fistula.The absolute pro was implanted in the fistula, without issue, and post dilated with an 8x40mm armada 35 balloon dilatation catheter (bdc).After post dilatation, the stent was noted to be fractured in the mid area.The vessel was opened up after post dilatation with the balloon; therefore, no additional treatment was needed and the fractured stent was left as is.The procedure was complete at this time.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
