HALO TECHNOLOGY^{9,10,11,12,13}

The proprietary technology incorporated in the HALO³⁶⁰ and HALO⁹⁰ Systems is designed to maximize clinical outcomes and completely remove the Barrett's epithelium without significant injury to the underlying tissue.

Bipolar electrode array geometry precisely controls the depth of ablation to < 1 mm.

• 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, even after multiple energy applications

PRECISE DEPTH CONTROL

Barrett's epithelium is approximately 500 µm in thickness. The HALO Energy Generator and the HALO Ablation Catheter electrode array are designed to work in concert to achieve a uniform, superficial depth of ablation of ~1,000 µm.

PREDICTABLE OUTCOME

In both porcine and human esophagectomy studies, the HALO Technology has demonstrated removal of the esophageal epithelium without significant injury to the submucosa when using the recommended treatment settings.
