HALO 360+
CIRCUMFRENTIAL ABLATION USING THE HALO360 SYSTEM
Removal of the Barrett's epithelium with the HALO360 System is an outpatient procedure that takes place in an endoscopic suite or operation room within a hospital.
Using standard endoscopic techniques under conscious sedation, the HALO360 System 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 oesophagus is measured.
- The sizing balloon is removed, leaving 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 alongside the ablation catheter.
- The catheter is positioned at the proximal margin of the targeted tissue. 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 visualisation.
3) Clean & Repeat:
- The coagulum is removed from the ablation zone. In addition, 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 alongside the ablation catheter.
- The ablation steps are repeated. The endoscope, guidewire and ablation catheter are removed under direct visualisation.
- Endoscopy is repeated.
