LigaSure™ Technology

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, when used with the ForceTriad™ energy platform
Seals withstand three times normal systolic blood pressure
Feedback-controlled response system automatically discontinues energy delivery when the seal cycle is complete, eliminating the guesswork

TissueFect™ sensing technology is the control system for the ForceTriad™ energy platform, designed to precisely manage energy delivery, creating a range of options for desired tissue effect. TissueFect™ sensing technology monitors changes in tissue impedance 3,333 times a second, and adjusts energy output accordingly to deliver the appropriate amount of energy for the desired tissue effect.

LigaSure™ vessel sealing technology has been updated and improved in the ForceTriad™ energy platform, controlled by TissueFect™ sensing technology. LigaSure™ tissue fusion, like LigaSure™ vessel sealing, uses the body’s own collagen and elastin to create a permanent fusion zone. This technology can fuse vessels up to and including 7 mm, lymphatics, tissue bundles and pulmonary vasculature, and has an average seal cycle of two to four seconds in most surgical situations.
