The BiZact™ tonsillectomy device allows surgeons to remove tonsils efficiently, with less bleeding1-3,† and minimal tissue damage.4-6 So patients may experience less pain after surgery.4-6,§

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 3 mm in diameter([FOOTNOTE=BiZact™ Tonsillectomy Device [instructions for use]. Boulder, CO: Medtronic; 2017.],[ANCHOR=],[LINK=])
  • Ergonomic handle for comfort in both hands

Features

Outperforms other tonsillectomy technologies

From a fast and easy setup7,₤ to reliable seals that reduce intraoperative bleeding,1-3,†  the BiZact™ device improves efficiency throughout procedures.1,7-10,‡ With a low energy profile and minimal tissue damage,4-6 patients may also experience less pain after surgery.4-6,§

Compared to published literature on the rate of intraoperative bleeding in tonsillectomy using electrosurgery, the Coblator™* instrument, and cold knife, the BiZact™ device reduces bleeding during surgery.1-3,†  

The BiZact™ device is also easier to set up than the Coblator™* instrument.7,₤

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 permanent seal
  • Automatically stop energy delivery when the seal is complete

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

  • Offers fast and easy setup7,₤
  • Produces seals that withstand 3x normal systolic blood pressure([FOOTNOTE=Based on internal test report #RE00077022, Porcine testing: probability of burst ≥ 360 mm Hg is ≥ 96.1%. Jan. 9–10, 2017.],[ANCHOR=],[LINK=])
  • Reduces bleeding during surgery1-3,†
  • Improves procedural efficiency1,7-10,‡
  • Minimizes tissue damage,4-6 which may reduce postoperative pain4-6

  • †Average intraoperative bleeding in 17 cases was 7.3 mL for BiZact™ device, compared to published literature results for Coblator™* device (10.83 mL) and electrocautery (27.08 mL), and cold knife (125 mL).

  • ‡Average procedure time in 17 cases for the BiZact™ tonsillectomy device was 9.35 minutes, compared to published literature results for electrocautery (14.8  minutes pediatric, 20.5 minutes adult)8 and the Coblator™* device (16.32 minutes).

  • §Low thermal damage has been shown in published studies to result in less postoperative pain. The Bizact™ device has been shown to produce <1 mm thermal spread, but has not been directly evaluated for pain reduction.

  • ₤12 out of 12 surgeons and 13 out of 15 nurses surveyed agreed.
