Ablating liver tumors with confidence

When other treatments like resection, embolization and chemotherapy are not an option for your patient or you are looking for combined treatments, ablation provides a minimally invasive solution. The problem is — given the limitations of most ablation technologies — many clinicians do not have confidence that they’ve ablated the entire targeted lesion. And failure to fully ablate could increase the chances of recurrence.

So we partnered with clinicians to develop a truly predictable ablation technology. 

It’s called Thermosphere™ technology, and it provides clinicians with three kinds of spatial energy control — thermal, field and wavelength. This maintains a predictable, spherical ablation zone throughout a procedure, and brings new confidence to the ablation of liver tumors. 

Emprint™ ablation system can be used for ablation in other soft tissue within the body.

Field Control shapes electromagnetic fields by controlling electrical currents on the radiator.


Thermal Control prevents unintended heating of tissue by hot microwave cables within the antenna shaft.

  • improves reliability
  • is important for Wavelength Control

Wavelength Control makes Thermosphere™ technology different. Other technologies in the market may have field and/or thermal control but wavelength is the differentiator that maintains a spherical shape throughout the ablation. Wavelength Control minimizes the elongation of the wavelength on the radiator to maintain effective field control.

With Thermosphere™ technology the Emprint™ ablation system creates predictable ablation zones across a wide range of tissue types.([FOOTNOTE=Based on internal porcine testing “In vivo Performance Testing of the Emprint™ Microwave Ablation System in a Porcine Model,” conducted during November 2013; R0043973.],[ANCHOR=],[LINK=]) This increases confidence for achieving planned results with precision and consistency on every procedure.

Additionally, the ability to create both small and large spherical ablation zones with a single antenna may reduce procedure times and costs.([FOOTNOTE=Emprint™ device IFU: Percutaneous Antenna with Thermosphere™ Technology; 1058196.],[ANCHOR=],[LINK=])
