Conditions: Obesity; Overweight

Summary: the primary objective of this study is to demonstrate the safety and efficacy of the elipse gastric balloon system for the treatment of obese adults.

this is a prospective, double-blinded, randomized, two-phase study to be conducted in a planned 400 obese individuals drawn from up to 15 sites. the treatment duration of the study is 48 weeks.
