Using our patented Thermosphere™ technology, the Emprint™ HP ablation generator enables a minimally invasive procedure with:
We've been the leading partners of life-transforming technology for the past 25 years — and we couldn't have done it without you. Together, we'll help to alleviate pain, restore health, and extend life, today and tomorrow.
Our patented Thermosphere™ technology can help lower the chance of local tumor recurrence by achieving large ablation volumes with predictable margins.7
Our purpose-built innovation helps you eradicate your patients’ non-resectable liver tumors and preserve more of their healthy parenchyma4,6 — because their future depends on both.

Emprint™ ablation system with Thermosphere™ technology
The Emprint™ ablation system enables a minimally invasive procedure with recovery time,11,12 high accuracy,7 and predictable margins.7
Emprint™ percutaneous antennas with Thermosphere™ technology
The Emprint™ ablation generator is compatible with the Emprint™ percutaneous ablation antenna. Our patented Thermosphere™ technology creates a predictable ablation zone focused at the end of the antenna, with no significant influence from varying tissue conditions.7
Antennas are available in three lengths: short (15 cm), standard (20 cm) and long (30 cm).
Conclusion: Thermosphere™ microwave ablation (T-MWA) is a safe and effective treatment for colorectal liver metastases (CLM) with no biliary complications reported in more than 200 ablated lesions. local tumor progression-free survival (LTPFS) is affected by lesion size at ablation, number of lesions, minimal ablation margin, and intra-segment progression. Chemotherapy before ablation (CBA) modifies kinetics growth of the lesions but deteriorates ablation margins and does not significantly impact local tumor progression-free survival.

Study design: A single-center, retrospective cohort study comparing 48 subjects with hepatic tumors (total 56 tumors) treated with Emprint™ ablation system with Thermosphere™ technology to subjects who underwent conventional high-frequency MWA (n=20) or low-frequency MWA (n=20).
