Essential Energy in Your Hands

In 1999, we revolutionized surgery with the introduction of LigaSure™ vessel-sealing technology — and we didn’t stop there. Our latest innovation, the LigaSure™ curved jaw device, brings proven LigaSure™ technology to a reposable device that is both easy to use and cost effective. 

Let’s put the most innovative tools in your hands. And let’s put patients first and work together to redefine the standard of care with LigaSure™ technology in open surgery.

Proven Patient Outcomes 

LigaSure™ technology:

  • provides control, confidence and consistent vessel sealing([FOOTNOTE=Based on a marketing survey during usability lab conducted by Covidien in the US. report: “LigaSure™ LF3225/LF3225C Curved Jaw, Open Sealer/Divider, Marketing Survey Report of US Validation Lab”, USA, May 2014, R0061090.],[ANCHOR=],[LINK=])
  • is supported by more than 1,000 peer-reviewed clinical studies and has been used in more than 10 million procedures worldwide([FOOTNOTE=Based on internal data derived from IRC clinical study research completed on January 22, 2014 and sales research completed on July 9, 2013; US140237.],[ANCHOR=],[LINK=])
  • has been shown to significantly reduce post-op pain, length of hospital stay and blood loss compared to alternative ligation methods([FOOTNOTE=Silva-Filho A, Rodrigues A, Monteiro M, et al. Randomized study of bipolar vessel sealing system versus conventional suture ligature for vaginal hysterectomy. Eur J Obstet Gynecol Reprod Biol. 2009; 146(2): 200–203.],[ANCHOR=],[LINK=]),([FOOTNOTE=Ding Z, et al. Use of LigaSure bipolar diathermy system in vaginal hysterectomy. Journal of Obstetrics Gynaecology. 2005 Jan;25(1):49-51.],[ANCHOR=],[LINK=]),([FOOTNOTE=Tamussino K, Afschar P, Reuss J, Perschler M, Ralph G, Winter R. Electrosurgical bipolar vessel sealing for radical abdominal hysterectomy. Gynecol Oncol. 2005;96(2): 320-322.],[ANCHOR=],[LINK=]),([FOOTNOTE=Manouras, Filippakis, Dimitrios et al.

Med Sci Monit, 2007; 13(5): CR224-230.],[ANCHOR=],[LINK=])


LigaSure™ technology helps manage costs by significantly reducing procedure time and patients’ hospital stay4,([FOOTNOTE=Levy B, Emery L. Randomized Trial of Suture Versus Electrosurgical Bipolar Vessel Sealing in Vaginal Hysterectomy. Obstetrics and Gynecology. 2003 Jul;102(1):147-151.],[ANCHOR=],[LINK=]),([FOOTNOTE=Cronje HS, et al. Electrosurgical bipolar vessel sealing during vaginal hysterectomy. Int J Gynaecol Obstet. 2005 Dec;91(3):243.],[ANCHOR=],[LINK=])
Features a reusable clamp along with a disposable single-use electrode to minimize waste compared with single-use devices([FOOTNOTE=Based on internal test report #R0058454, LF3225 – Marketing claims China validation lab – plan and report. April 2014.],[ANCHOR=],[LINK=])


The clamp-like design feels familiar in your hand. It is intuitive for surgeons without previous LigaSure™ experience and allows for excellent control.9
Combining the essential elements of surgery: grasping, sealing and cutting, the exchange of instruments is minimized as compared to mechanical ligation.9
