The company already makes LAP-BAND, the only adjustable implant device for individual weight loss approved in the country. Allergan also manufactures a nonsurgical intragastic balloon that is used outside the United States to treat obesity. According to an article in the Red Herring, Johnson & Johnson will be providing some competition, as it's slated to enter the U.S. market with its Swedish Adjustable Gastric Band this year. Its subsidary Ethicon Endo-Surgery has already made the product available in Europe.
