Heliosphere BAG is a non-surgical temporary intragastric balloon system used to treat obesity with an implantation duration of 6 months. The volume of the Heliosphere BAG balloon is 550 cm3 (10 cm in diameter). The lightness of the air-filled Heliosphere balloon limits nausea and vomiting (less than 30 grams).
