Reliable Technology. More Efficient Patient Care.

We’re raising the bar on the standard of care in vessel sealing. The nonstick coating on the jaws of the LigaSure Impact™ device delivers the reliable performance of LigaSure™ technology — with greater efficiency and fewer procedural interruptions.([FOOTNOTE=Lig-40 Report Product Claim LF4418 RE00057355.

Overcoming Clinical Challenges

Eschar buildup can cause jaws to stick, affect device performance, and require multiple cleanings that disrupt procedural flow. Our coated jaws help to solve this problem, and bring the value of greater efficiency to the OR — for patients, physicians, and the healthcare industry. 


Less Sticking. Easier Cleaning. Greater Efficiency.

The LigaSure Impact™ device can grasp, seal, and cut tissue independently — or you can perform all three in one step. The device’s large jaws also:

  • Enable fast transection([FOOTNOTE=Based on internal test report #RE00052321, Lig-40 marketing report surgeon evaluation of LigaSure Impact™ LF4418: independent surgeon feedback collected during porcine labs. June 21-22, 2016.],[ANCHOR=],[LINK=])
  • Minimize the need for multiple activations2
  • Facilitate procedural efficiency2

But the latest innovation comes from the nonstick coating on the LigaSure Impact™ device jaws. Because compared to our legacy device, the nonstick coating:

  • Reduces sticking by 67%([FOOTNOTE=Based on internal test report #RE00034755, LF4418 design verification report: benchtop testing using porcine abdominal aorta, mesentery, and renal arteries, with average (lbs.) sticking force. Feb. 24, 2016 and March 25, 2016.],[ANCHOR=],[LINK=]) 
  • Reduces eschar buildup by 50%([FOOTNOTE=Based on internal test report #RE00057355, Lig-40 report product claim LF4418: benchtop testing using porcine uterine tissue. Eschar buildup assessed using optical imaging analysis after 20, 40, and 60 seal and divide cycles.  July 29, 2016.­],[ANCHOR=],[LINK=]),†
  • Results in fewer cleanings4,‡
  • Makes cleaning more efficient4,‡

The end result is a smoother procedure — for surgeons and patients.

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([FOOTNOTE=Lamberton GR, Hsi RS, Jin DH, Lindler TU, JellisonFC, Baldwin DD. Prospective comparison of four laparoscopic vessel ligation devices. J Endourol. 2008;22(10):2307-2312.],[ANCHOR=],[LINK=])
  • Reduce blood loss compared to sutures and clips([FOOTNOTE=Ding Z, Wable G, Rane A. Use of LigaSure bipolar diathermy system in vaginal hysterectomy. J Obstet Gynaecol. 2005;25(1): 49-51.],[ANCHOR=],[LINK=]),([FOOTNOTE=Levy B, Emery L. Randomized trial of suture versus electrosurgical bipolar vessel sealing in vaginal hysterectomy. Obstet Gynecol. 2003;102(1):147-151.],[ANCHOR=],[LINK=])
  • Reduce procedure time compared to sutures7,8
  • Reduce patient length of stay compared to sutures7

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

  • Significantly reduce operative blood loss in colorectal, gynecologic and urologic surgery7,8,([FOOTNOTE=Targarona, et al.

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.
