About RFA Therapy
Advanced Ablation Technology for Barrett's Esophagus
The HALO System is designed to remove the Barrett's epithelium in a short, well-tolerated endoscopic procedure and offers an alternative to "watchful waiting" for patients with intestinal metaplasia, low-grade, and high-grade dysplasia.
HALO System Includes:
Capable of treating circumferential segments ≥ 3cm
- Provided primary or secondary treatments for smaller areas such as islands and tongues.
- Can be used as a secondary treatment after circumferential ablation or other therapeutic devices.
- Clinical evaluations completed for all types of Barrett's tissue
- Comprehensive peer reviewed publications including the New England Journal of Medicine
- Prospective, multi-center, HALO patient registry allows for treatment and follow-up under a centralized IRB approved protocol
Barrett's epithelium is approximately 500 µm thick. The HALOFLEX Energy Generator and the HALO Ablation Catheter electrode array are designed to work in concert to achieve a uniform, superficial depth of ablation between ~500 µm and ~1,000 µm.
Human Esophagus Specimen (H&E Stain)
The proprietary technology incorporated in the HALO System is designed to maximize clinical outcomes and completely remove the Barrett's epithelium without significant injury to the underlying tissue.
HALO Ablation Catheter Electrode
The geometry of the bipolar electrode array helps to precisely control the depth of ablation to < 1000 µm.
- Delivery of ablative energy in less than 1 second allows long or short segments of Barrett's to be treated quickly
- Consistent application of bipolar energy uniformly removes the esophageal epithelium, reducing potential for buried glands and improving patient tolerability
- Controlled treatment depth of less than 1,000 µm reduces risk of stricture formation
