Improved versatility and procedural efficiency over RFA systems

The Evident™ ablation system uses microwave energy to create more time-efficient ablations, with less dependence on tissue and tissue temperature than radiofrequency ablation (RFA). This makes microwave energy less susceptible to radiofrequency impedance and perfusion.

Evident™ MWA antennas can be used alone or in clusters providing a variety of techniques for ablation of multiple and large, nonresectable, soft-tissue lesions.



Minimized set up.

When using the Evident™ MW ablation surgical antenna, system set up is a three-step procedure: Connect the antenna to the generator, set power and set time.

Simultaneous antenna use.

Simultaneous activation of multiple Evident™ MW ablation antennas allows for a more time-efficient procedure, especially in patients with multiple lesions, compared to other ablation techniques, such as cryoablation and RFA.([FOOTNOTE=Martin RC, Scoggins CR, McMasters KM.

Multiple-use antennas.

Evident™ MW ablation antennas are versatile, and can be used for hepatic tumor ablation, coagulation of tissue prior to resection, or both, all with Covidien ablation technology.
