Providing exposure for distal anastomosis is sometimes challenging in total arch replacement via median sternotomy. A new self-expanding ring, which is contracted in diameter by catching two holes in the ring with a long curved-clamp, may provide better exposure, and facilitate the procedure. This contraction creates the tension needed for the ring to expand once delivered to the distal anastomosis when the clamp is removed. This ring can be placed easily, even in a deep surgical field, and can maintain free space around distal aortic stump.
