The invention of obesity continued to prevent the phone as a nutrient food is absorbed into the body by the bile relates to a balloon for a stent treatment for preventing the increase in obese patients, and more particularly, one of which proceeds in the longitudinal direction of the body to create a cylindrical shape by overlapping the two-layer plastic composite is uniformly divided by the circumference having a swelling agent injection port forming an expanding portion and a plurality of distribution expansion injection with a distribution injection port communicating with the distribution passage formed in the circumferential direction so that the expansion portion communicates with the injection inlet is formed in the longitudinal opposite end of swelling agent, and injecting the expanding portion formed in a distribution body group resected portion interconnecting parts connecting the expansion stage in a longitudinal direction, but formed as a one-piece removable expansion that is separate from the expanding portion to be left in any form, the removable expansion pour distribution expansion portion and forming the injection expansion molding so that the bent portion to the outside to form a balloon (balloon) type stent and balloon-type group is formed of a flexible length of the duodenum to the body cavity by the lower end portion is formed to be a one-piece expansion of the stent and is woven together with a line to connect the fastening of the thin cylindrical tube thickness is characterized in that configuration.본 발명은 음식물이 담즙에 의해 영양소로 전화되어 인체로 흡수되는 것을 방지하여 비만도의 지속적인 증가를 방지하는 비만 환자 치료용 벌룬스텐트에 관한 것으로, 더욱 상세하게는 합성비닐을 두 겹으로 겹쳐 원통 형상으로 제작하는 몸체의 길이방향으로 진행되며 원주를 따라 균일 분할하여 팽창제주입구가 구비되는 하나의 주입팽창부 및 상기 주입팽창부의 팽창제주입구가 형성된 길이방향 반대편 끝단에 연통되도록 원주 방향을 따라 형성된 분배통로에 연통하는 분배주입구를 갖는 다수 개의 분배팽창부를 형성하고, 기 몸체에 형성된 주입팽창부와 분배팽창부를 상호 연결하는 연결단을 길이방향을 따라 일부분 절제하여 일체 형태로 남겨지는 일체형 팽창부와 분리되는 분리형 팽창부로 형성하되, 상기 분리형 팽창부을 형성하는 주입팽창부와 분배팽창부는 외측으로 휘어지도록 성형하여 벌룬(balloon)형 스텐트를 형성하고, 기 벌룬형스텐트
