Overview

The LigaSure Atlas™ handset is a single-use instrument with vessel sealing and tissue dividing capabilities. It is targeted for use in general procedures where ligation and division of vessels are performed.

The LigaSure Atlas™ handset has a 20 or 37 cm shaft and is designed to fit down a 10 mm cannula. The shaft can be rotated up to 359 degrees via a rotation knob. The ergonomically designed handset provides one-handed operation of grasping, rotation and cutting. Sealing occurs by ratcheting the handle and activating through the purple button on the device or through the LigaSure footswitch.

LigaSure™ Technology – Delivering Performance Beyond Expectations

Across the range of products and procedures, LigaSure™ technology delivers a unique combination of pressure and energy to create a consistent seal with each application.

  • 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

LigaSure™ instruments have been found to:

  • Have the highest burst pressure, fastest sealing time and were highest rated overall compared to Gyrus PK™*, Harmonic ACE™* and ENSEAL™*([FOOTNOTE=Lamberton GR, Hsi RS, Jin DH, Lindler TU, JellisonFC, Baldwin DD.

  • Reduce blood loss compared to sutures and clips([FOOTNOTE=Ding Z, Wable G, Rane A. Use of LigaSure bipolar diathermy system in vaginal hysterectomy.

  • Reduce patient length of stay compared to sutures3

What is TissueFect™ sensing technology?

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.

What is LigaSure™ tissue fusion?

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.
