Overview:

Reach for Perfection.

LigaSure™ Maryland jaw 44 cm laparoscopic sealer and divider (LF1744) is a multifunctional device that delivers efficiency and versatility by combining one-step sealing and the functionality of a Maryland dissector, atraumatic grasper, and cold scissors with the reliability of LigaSure™ technology.

The design of the LigaSure™ Maryland jaw allows for more efficient transection speed with one-step sealing, allows for minimal steps when sealing and dividing, and enables reduced instrument exchanges.1

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™*1
  • Reduce blood loss compared to sutures and clips 2, 3
  • Reduce procedure time compared to sutures 2,3
  • Reduce patient length of stay compared to sutures 2

Compared to mechanical ligation techniques, LigaSure™ technology has been shown to:

  • Significantly reduce operative blood loss in colorectal, gynecologic and urologic surgery 4-9
  • Significantly reduce perioperative blood transfusions in gynecologic, urologic and general surgery 8, 10, 11
  • Significantly reduce procedure time in colorectal, gynecologic and urologic surgery 4, 6, 7, 9, 12, 13
  • Significantly reduce length of hospital stay in gynecologic and urologic surgery 6, 13

Compared to other energy-based modalities, LigaSure™ technology has been shown to:

  • Significantly reduce operative blood loss in colorectal and gynecologic surgery 14-17
  • Significantly reduce procedure time in colorectal and gynecologic surgery 14, 17

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.
