a TransForm™ Occlusion Balloon Catheter with a catheter length of 150 cm, proximal outer diameter of 2.8 Fr, distal outer diameter of 2.7 Fr, distal tip of 3.25 mm, and fluoro-saver marker 94 cm from the distal tip. b 4 × 10 mm HyperGlide with four proximally located inflation and deflation ports as compared to a 4 × 10 mm TransForm Occlusion Balloon Catheter with micromachined slits for inflation and deflation (designed to allow for faster deflation, the use of higher contrast levels, increased visibility, and reduced procedure times).
