ablation zone examples |
|
The following are examples of potential ablation results using single and multiple Evident™ MWA Percutaneous Antennas to coagulate tissue prior to resection. These examples are from ex vivo animal tissue (liver) models. The size of ablation zones may vary in clinical settings. |

Evident™ MWA System Tissue Verification Testing Protocol
Ablation zone is dependent upon tissue vascularization, type, temperature and impedance.
Ablation zone testing was performed in healthy ex vivo bovine 20°C liver. Ablation zones may vary in clinical settings.
Illustrations of ablation zones are not to scale.
