HALO360 System

The HALO360 System includes an energy generator, ablation catheters, and sizing balloons. The energy generator is used to inflate the sizing balloons in order to measure the inner diameter of the targeted portion of the esophagus, and is used to deliver RF energy to the ablation catheters to achieve the ablative effect. All catheters are single use, disposable medical devices. The following image depicts the energy generator (background) and an ablation catheter (foreground).

HALO90 System

Focal ablation of residual Barrett’s tissue may be conducted with the HALO360 device or a focal ablation device, the HALO90 device, capable of more selective tissue ablation. The HALO90 is substantially equivalent to the HALO360, having the same electrode design and delivering the same energy density and power density to the tissue. The difference is that the surface area is smaller, allowing more focal selective ablation of residual Barrett’s tissue, and this device is attached to the endoscope, rather than to a balloon catheter. The following images depict the ablation catheter. The generator is similar to the HALO360 energy generator.
