Circumferential Ablation
Using standard endoscopic techniques under conscious sedation, the HALO360+ Ablation Catheter facilitates rapid ablation of long and short segments of Barrett's epithelium:
1. SIZE
- The endoscope is introduced to identify the anatomic landmarks and length of the Barrett's epithelium. A HALO Guidewire is inserted and the endoscope is removed.
- The HALO360+ Sizing Balloon is introduced over the guidewire. The inner diameter of the esophagus is measured.
- The sizing balloon is removed, leaving the the guidewire in place.
- Based on the smallest sizing measurement, the appropriate ablation catheter is selected.

2. ABLATE
- The HALO360+ Ablation Catheter is introduced over the guidewire.
- The endoscope is inserted along-side the ablation catheter.
- The catheter is positioned at the proximal margin of the targeted tissues. The ablative energy is delivered. The catheter is moved distally to treat all targeted tissue.
- The endoscope, guidewire, and ablation catheter are removed under direct visualization.

3. Clean & Repeat
- The coagulum is removed from the ablation zone with the HALO CAP mounted on the endoscope. The electrode surface of the ablation catheter is cleaned outside the body.
- The ablation catheter is re-introduced over the guidewire. The endoscope is inserted along-side the ablation catheter.
- The ablation steps are repeated. The endoscope, guidewire, and ablation catheter are removed under direct visualization.
- Endoscopy is repeated.
