It was reported that the 5.0 x 8 mm nc trek balloon dilatation catheter (bdc) was being used for post-dilatation of a very tight lesion.The balloon was inflated to nominal pressure and fully deflated without issue.However, when removing the balloon from the anatomy, the balloon had poor re-wrap and there was difficulty extracting the balloon even with force applied.The bdc could not be pulled into the 6fr guiding catheter, so the entire system was removed together.There was no reported adverse patient effect.There was no reported clinically significant delay in the procedure.No additional information was provided.
