How it Works


Predictable and Precise Tissue Interaction

CO2 laser energy is highly absorbed in water and cuts tissue by vaporizing the water content of cells at the tissue surface. High absorption of CO2 laser energy in water leads to a predictable and controlled tissue interaction with a thermal effect of approximately 150 microns.1  Electrosurgical energy relies on tissue conductivity, causing a less predictable thermal spread and a tissue effect that is approximately 10x greater.

Controlled Depth of Penetration

The BeamPath® System features a divergent beam, allowing the surgeon to easily control the depth of penetration by adjusting the distance to the tissue. Hemostatic cutting is achieved at close distances, while ablation and coagulation is achieved at distances farther away.
