Proximal Distal The following is a representation of the procedural steps used in prospective clinical trials for this device. This guide is not meant to replace physician judgment. Procedural steps may vary by patient according to patient tolerability, anatomy, motility, characteristics of the Barrett’s esophagus, and underlying health condition. QUICK VIEW OF PROCEDURAL ASPECTS 1.Introduce endoscope, measure TIM/TGF, insert guidewire  Flush with Mucomyst and suction out 2.Remove endoscope, leave GW in place  Calibrate Sizing balloon 3.Introduce sizing balloon over GW 4.Start sizing 12 cm proximal to TGF, every 1 cm 5.Remove sizing balloon, leave GW in place 6.Introduce HALO 360+ ablation catheter over GW 7.Introduce endoscope along-side ablation catheter 8.Position proximal electrode edge 1-2 cm proximal to TIM 9.Ablate each 3 cm segment until overlapping TGF 10.Remove endoscope, catheter, and GW together (with direct visualization) 11.Introduce endoscope and clean ablation zone 12.Inflate and clean ablation electrode (outside of body) 13.Re-Insert GW and remove endoscope, leave GW in place 14.Re-Introduce ablation catheter over GW 15.Repeat steps Remove both items, re-introduce scope and evacuate gastric contents, inspect ablation zone 22 TGF Quick Overview Circumferential Ablation
