Brief Summary

This is a multi-center, prospective study evaluating a treatment for obesity.

Detailed Description

This is a multi-center, prospective study evaluating a treatment for obesity using the g-Cath EZ and associated devices. The intent is to evaluate the safety and efficacy of a modified Snowshoe suture anchor placement pattern called Pose 2 (suture anchors placed in the mid + distal body of the stomach, with none placed in the fundus) along with a moderate intensity diet and exercise program. The g-Cath EZ and the associated devices (the g-Prox EZ, g-Lix & Transport) are known collectively as the Incisionless Operating Platform (IOP). Efficacy of the treatment will be evaluated based on changes in weight loss over 12 months, & adverse events will be recorded throughout the duration of the study.
