Summary
The HALO Patient Registry is a prospective/retrospective, multi-center patient registry. It provides a framework for treatment and follow-up of patients with Barrett's esophagus (non-dysplastic IM, LGD and HGD). The primary objective is to provide a tool for participating physician investigators to collect outcomes data related to the use of the HALO Ablation Systems.
