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.
