Eradicate non-resectable liver tumors1,2

Successful management of non-resectable liver tumors is about more than what you remove — it’s about what you leave behind, too.

Emprint™ SX helps you eradicate your patients’ non-resectable liver tumors and preserve more of their healthy parenchyma1,2 — because their future depends on both.

Emprint™ SX improves successful antenna placement

A study concluded this the unique 3-D ultrasound guided (3DG) ablation platform improves successful antenna placement versus standard ultrasound guidance (USG) upon first attempt.9 Results were independent of user experience and improvements were most pronounced in inexperienced users.

System characteristics that enable these results include:

  • Advanced 3-D tracking shows the position of the Emprint™ SX ablation antenna and ultrasound transducer relative to the surgeon’s perspective in real-time.4
  • Projected antenna path allows trajectory planning prior to antenna placement.9
