Ostial corporation has contacted the user facility; however, at this time no additional information regarding this case has been provided and the flash mini ostial system used was not available for return or evaluation.As such it could not be confirmed if there were any issues with the device used during the procedure.Based on the provided issue description, that the "balloon would not completely inflate during prep", it appears that use error may have contributed to this event the as per ifu the balloons are not supposed to be inflated during device preparation and are supposed to be left under vacuum or neutral pressure until they have been advanced to the target vessel in the patient.The manufacturing documentation and lot release testing for the flash mini device lot associated with this complaint was reviewed.No issues were noted that would have contributed to the reported issue of a balloon not inflating during prep.All devices passed the in-process leak checks and the lot release testing showed normal burst pressures and burst volumes.
