Abstract
Gastric space occupying devices are provided that include a stent configured for deployment in the gastrointestinal tract of a patient, and in particular, for deployment in the esophagus or the stomach. Secured to the stent is an expandable member that is adapted to reside within the patient's stomach. When expanded, the expandable member occupies a predefined volume within the patient's stomach and is further tethered to the deployed stent, thereby retaining or anchoring the expandable member within the stomach. Methods and systems for the deploying the space occupying devices are also provided.
