Clinical Evidence

Multi-institutional analysis of outcomes for Thermosphere™ microwave ablation treatment of colorectal liver metastases: the SMAC study

Conclusion: T-MWA is a safe and effective treatment for CLM with no biliary complications reported in more than 200 ablated lesions. LTPFS is affected by lesion size at ablation, number of lesions, minimal ablation margin, and intra-segment progression. CBA modifies kinetics growth of the lesions but deteriorates ablation margins and does not significantly impact local tumor progression-free survival.

The Emprint™ HP ablation generator gives you more volume, with a single antenna.

Using our patented Thermosphere™ technology, the Emprint™ HP ablation generator enables a minimally invasive procedure with:

  • Large ablations, with up to 40 percent more volume compared to the original Emprint™ ablation system10
  • Proven spherical shape,11-17 giving you flexibility in antenna placement approach5
  • Consistent ablative margins greater than 5 mm5,†
  • Scalability, allowing you to create both small and large ablation zones10

Take less healthy liver, help preserve their future6,7

Successful management of nonresectable liver tumors is about more than what you remove — it’s about what you leave behind, too. The Emprint™ ablation system enables a minimally invasive procedure that provides immediate, repeatable results4 and can help lower the chance of recurrence.8 This procedure can also be combined with additional therapies and help you give your patients a more comprehensive treatment.6
