Overview

Less bleeding.1,*
Minimal thermalspread.4,**,††,‡‡
More efficient tonsillectomy.1,2,3,†,‡,§

The BiZact™ tonsillectomy device allows surgeons to remove tonsils efficiently, with less bleeding1,* and minimal thermal spread.4,**,††,‡‡

The BiZact™ tonsillectomy device is the right tool for the job — and it makes all the difference.

A procedural solution from Valleylab™ energy, the BiZact™ tonsillectomy device features:

  • 12 cm shaft for access 
  • Curved jaw that follows the shape of tonsil bed
  • Intuitive controls to seal and divide tissue and vessels up to and including 3 mm in diameter5,‡‡
  • Ergonomic handle for comfort in both hands

Features

Outperforms Other Tonsillectomy Technologies

From a fast and easy setup2,3,§ to reliable seals that reduce postoperative bleeding,1,*  the BiZact™ device improves efficiency throughout procedures.1-3,†, ‡,§ With a low energy profile and minimal thermal spread.4,**,††, ‡‡

The BiZact™ device is also easier to set up than the Coblator™* instrument.2,3,§

Technology

LOW ENERGY LEVEL.
HIGH CLINICAL VALUE.

The BiZact™ device is an advanced bipolar tissue sealer and divider. It’s powered by Valleylab™ energy platforms that:

  • Measure impedance of clamped tissue 
  • Adjust energy output to create a reliable seal6-8,‡‡
  • Automatically stop energy delivery when the seal is complete

As a result of this technology, the BiZact™ device:

  • Offers fast and easy setup2,3,§,§§
  • Produces seals that withstand 3x normal systolic blood pressure5
  • Reduces postoperative bleeding during surgery1,*
  • Improves procedural efficiency1,2,3,†,‡,§
  • Minimizes thermal spread,4,**,††,‡‡
