It was reported that the procedure was to treat a mildly tortuous mid right coronary artery.A 5.0 x 8 mm nc trek balloon catheter was advanced to the lesion for post-dilatation and inflated to 16 atmospheres; however, the balloon did not refold properly and during removal of the catheter, the balloon caught on the end of the guiding catheter and could not be removed.Several inflations and deflations were made in an attempt to get the balloon into the guiding catheter but it could not be pulled into the guide and the proximal shaft separated at the hub.The devices were removed as a single unit and the balloon was wrinkled and bunched.There was no clinically significant delay in procedure and no adverse patient effects.No additional information was provided.
