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™ sealer/divider 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.

  • Results in fewer cleanings4,‡
  • Makes cleaning more efficient4,‡

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

Comfortable feel in your hands

The LigaSure Impact™ device is lightweight, comfortable to use, and the activation button is ergonomically positioned.2 It’s designed to optimize performance across a range of specialties, including:

  • Urology
  • Colorectal
  • General surgery
  • Gynecology

The jaws of the LigaSure Impact™ device also facilitate access because they follow the curve of the stomach and uterus.2
