Valleylab Ligasure Features

The 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
