Overview:

Trusted Performance. Enhanced Design.

The LigaSure™ 5 mm blunt tip 44 cm sealer and divider (LF1644) combines the signature sealing consistency of LigaSure™ technology with long cutting length, atraumatic grasping and blunt dissection.

Based on surgeon feedback, Covidien modified the LigaSure5 mm blunt tip devices to enhance performance and ease of use¹. Building on the consistency of predecessor devices, the LF1644 offers the following improvements1, 2*:

  • Improved blunt dissection
  • Better stability
  • Greater comfort and reduced fatigue 

This instrument offers a long cutting length compared to other commercially available 5 mm laparoscopic sealing devices. The LF1644 enables cutting independent of sealing, and provides sealing, grasping and access to surgical structures to accommodate a variety of laparoscopic procedures, including:

  • Adhesiolysis
  • Adrenalectomy
  • Colectomy
  • Laparoscopic hysterectomy
  • Nephrectomy
  • Oophorectomy
  • Roux-en-Y gastric bypass
  • Sleeve gastrectomy
  • Splenectomy
  • Whipple

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.
