Indications, Safety, and Warnings

Description

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% more volume compared to the original Emprint™ ablation system1​
  • Proven spherical shape,2–8 giving you flexibility in antenna placement approach9
  • Consistent ablative margins greater than 5 mm†​,9
  • Scalability, allowing you to create both small and large ablation zones1

Features

The Emprint™ HP ablation system supports your journey from careful planning to predictable success when treating nonresectable liver tumors. It enables a minimally invasive procedure with:

High accuracy10

Arrow target

Predictable margins9

Our patented Thermosphere™ technology can help lower the chance of recurrence by achieving large ablation volumes with predictable margins.7

The Emprint™ HP ablation procedure can be combined with additional therapies, like resection or chemotherapy, to give your patients a more comprehensive treatment.11

Compared to surgical resection, our purpose-built innovation helps you eradicate your patients’ tumors and preserve more of their healthy parenchyma7,12 — because their future depends on both. Take less healthy liver, give them more life.


Clinical results may vary. Not all patients’ results are the same.

Emprint™ percutaneous antennas with Thermosphere™ technology​

Both the Emprint™ and Emprint™ HP ablation generators are compatible with the Emprint™ percutaneous ablation antenna. Our patented Thermosphere™ technology creates a predictable ablation zone focused at the end of the antenna, despite varying tissue conditions.8

They are available in three lengths: short (15 cm), standard (20 cm), and long (30 cm).

Clinical evidence

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

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.
