LigaSure™ Technology

The world's most advanced vessel sealing and dissection technology

With 1300+ clinical papersplus internal benchmarking against other vessel sealing devices that claim to be ‘like’ LigaSure™, the difference is obvious within three seconds:

Best-in-class for 23 years

LigaSure™ Technology, powered by TissueFect™ on ValleyLab™ Energy Platforms, continues to be the world’s most advanced vessel sealing and dissection technology. 

  • In one second, LigaSure™ measures tissue impedance, calculates and adjusts energy output using a unique algorithm 434,000 times.2
  • Within two seconds, LigaSure™ reliably and consistently fuses vessels up to and including 7mm in diameter, with seals that withstand 3x Normal Systolic Pressure.3
  • In three seconds, a surgeon using LigaSure™ Technology can seal a vessel, dissect and safely move onto the next part of the procedure3,6,7, due to the faster cooling times (under <60 degrees in less than one second8) and unique nano-coating.*
