The BiZact™ tonsillectomy device is the right tool for the job — and it makes all the difference.
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,§
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 diameter¹¹
- Ergonomic handle for comfort in both hands
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,₤
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 pressure12
- 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.
