ESSENTIAL Trial™ Sham Cross-over

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.
