Overview

Less Sticking.3,‡ Less Buildup.2,†
More Efficient Procedures.2,§

Nonstick nano-coating technology enhances the performance of the LigaSure™ Maryland jaw device.

The multifunctional LigaSure™ Maryland jaw device now delivers even greater procedural efficiency.1,2,§

Because — compared to the legacy device — the new nonstick nano-coated jaws:

  • Reduce eschar buildup2,†
  • Decrease instances of sticking3,‡
  • Lead to fewer jaw cleanings — and make cleanings easier2,§

So you get these benefits in addition to the performance you expect from the LigaSure™ Maryland jaw device.

TECHNOLOGY

Reliable Performance. Greater Efficiency.3,§

We added nonstick nano-coating technology on the LigaSure™ Maryland jaw device to help you tackle challenges both big and small.

The new LigaSure™ Maryland jaw device is designed to help you treat patients — reliably and efficiently.3,§

Because we combined the benefits of nonstick nano-coating technology with the proven performance of LigaSure™ vessel-sealing technology.

Nano-coating is a highly controlled, thin-film coating with uniform thickness. It covers the entire jaws of a LigaSure™ device without impacting the intelligent vessel-sealing algorithms of Valleylab™ energy platforms.7

Reduce sticking4,‡ improve efficiency3,§

For the LigaSure™ Maryland jaw device, compared to its uncoated counterpart, that means: 

  • Less eschar buildup3,††
  • Less sticking4,‡
  • Fewer jaw cleanings4,§

The net benefit is smoother, more efficient procedures.3,§

The confidence of control and consistency

LigaSure™ technology has been setting the standard of care for vessel sealing for nearly two decades.

LigaSure™ technology uses the body’s own collagen and elastin to create a permanent seal that can withstand three times normal systolic blood pressure.8 It’s been used in more than 19 million procedures worldwide.9,§§§ And is supported by an ever-growing body of clinical evidence.

With an average seal cycle of one to four seconds in most surgical situations,10 LigaSure™ technology can seal vessels up to and including 7 mm, lymphatics, and tissue bundles. It also eliminates the guesswork — and minimizes thermal spread11 — by automatically discontinuing energy delivery when the seal cycle is complete.9

Made even better by the Valleylab™ FT10 energy platform

The LigaSure™ Maryland jaw portfolio works great when powered by the ForceTriad™ energy platform with 3.6 software and higher. For optimal performance, use it with the Valleylab™ FT10 energy platform.

The Valleylab™ FT10 energy platform makes LigaSure™ devices better than ever.10,12
