7 Reasons why you should use the Ligasure™ Maryland jaw thoracic device

We believe in true innovation

LigaSure™ technology has been used in more than 25 million procedures worldwide.1

The LigaSure™ Maryland jaw thoracic device (LF1930T) is the first and only minimally invasive LigaSure™ device on the market specifically indicated for sealing pulmonary veins and arteries/vessels up to, and including, 7 mm.2

"7 Reasons Why" you want to bring the Right Energy to your thoracic cases with the Ligasure™ Maryland jaw thoracic device (LF1930T):

Reliable Hemostasis

For 7 mm pulmonary vasculature, the device also seals and transects adhesions.2-8

Improved Access

30 cm shaft designed specifically for access to the thoracic cavity.4–8


The device has the benefits of being a Maryland dissector9,11, one – step sealer13, atraumatic grasper9,11. cold scissors9,13 and it may reduce instrument exchanges9,10 and procedure time9,14.

Effective Blunt Dissection

For dissecting around the recurrent nerve and lymph nodes without causing damage9,11

Cooler Jaws

Cooler jaw temperature and faster cool down times compared to Harmonic HD1000i™*9,12,§.

Coated Jaws

Proprietary nano‑coating on the jaws to reduce sticking9,15,Φ, eschar buildup15,16 and cleanings9,17,Ω.

Better Visualization

The curved jaw allows for better access, visualization and easy skeletonization of vessels9,10.
