essential trial™ sham cross-over

Conditions: Obesity

Summary: this is a multicenter, un-blinded, open label, pivotal supplemental study to g130163 intended to evaluate the safety and efficacy of treating previous sham subjects in the essential pivotal trial (ide#g130163) with the active treatment (the placement of g-cath ez suture anchors along with diet and exercise). compliant sham subjects (those who attended all primary ide follow-up visits and who continue to meet eligibility criteria as described in this protocol) will be offered this active treatment after their 12 month unblinding visit in the essential pivotal trial.
