The device was returned for evaluation and the clinical observation could not be confirmed.Upon receipt of the device, there were no damages found with the occlusion balloon catheter hub, body, or distal tip.During evaluation, an attempt was made to flush the occlusion balloon catheter with water, but it was found to be occluded and the cause is likely due to the dried contrast inside.The balloon subassembly was separated (cut) from the catheter body in order to test the balloon for inflation and a leak was found distal to the distal marker band.Upon examination, a defect (hole) was found in the balloon chronoprene tubing.Based on the returned device evaluation, there was no rupture found on the balloon catheter; however, the device evaluation showed the balloon could not maintain inflation due to the defect (hole) in the chronoprene tubing.The defect observed is more consistent with mechanical or navigation related damages rather than those caused by over-inflation (rupture).The customer reported that the balloon was successfully tested prior to use in the patient; therefore, the damage likely occurred during the procedure.All balloons are 100% leak tested and all devices are 100% inspected for damages and irregularities during manufacture.If information is provided in the future, a supplemental report will be issued.
