It was reported that the procedure was to treat a mildly tortuous saphenous vein graft.A 5.0 x 15 mm trek balloon catheter was used.The device was being advanced over an unspecified guide wire that was inside the anatomy, and did not meet any resistance during advancement.However, it was noted that the shaft of the device may have been kinked before loading onto the guide wire.The hypotube then separated from the device outside the anatomy; therefore, the device was simply pulled out.An unspecified balloon catheter was then used to successfully complete the procedure.There was no clinically significant delay in the procedure and no adverse patient effects.No additional information was provided.
