ValleyLab LigaSure Vessel Sealing System Features
The ValleyLab LigaSure Vessel Sealing System gives you something no other electrosurgical tool can – permanent vessel occlusion.
The LigaSure™ system's revolutionary technology replaces almost all other hemostatic tools because it doesn't just ligate vessels, it actually fuses vessel walls to create a permanent seal.
- Provides a combination of pressure and energy to create vessel fusion
- Permanently fuses vessels up to and including 7 mm in diameter and tissue bundles without dissection or isolation
- Average seal cycle is 2 to 4 seconds
- Seals withstand 3 times normal systolic blood pressure
- Feedback-controlled response system automatically discontinues energy delivery when the seal cycle is complete, eliminating the guesswork
