The idea for the B-Clamp® was conceived by leading bariatric surgeon Moises Jacobs M.D.  as a reversible sleeve-like procedure and an alternative to the existing surgical procedures and products which have limited effectiveness or that develop many side effects for patients.


In 2009 ADVANCED BARIATRIC TECHNOLOGY, LLC.  (ABT) was incorporated in Florida, USA as a privately held Limited Liability Company for the purpose of doing R&D, Engineering and bringing the product from a concept to a reality.  ABT has strategic partnerships with leading medical device developers and manufacturers to make the B-Clamp® a success in addressing the growing world-wide need for obesity therapy .

ABT currently has a significant portfolio of US and International Patents and trademarks related to the B-Clamp® .
