LigaSure Vessel Sealing Devices

What is LigaSure?

LigaSure is the advanced bipolar vessel sealing technology from Covidien, now part of Medtronic. These instruments combine jaw pressure with controlled energy to seal vessels and tissue bundles, and most models include an integrated cutting blade, so the surgeon can seal and divide without exchanging instruments.

Choosing the right instrument

• Maryland jaw (LF1923, LF1937, LF1944): a curved, tapered jaw for fine dissection, in 23cm, 37cm and 44cm shaft lengths.
• Exact dissector (LF2019): a slim, curved jaw for precise open dissection.
• Blunt Tip (LF1823, LF1837, LF1844): a blunt jaw for sealing and dissection in open and laparoscopic cases.
• Impact (LF4418): a large curved jaw for open procedures with larger tissue bundles.
• Small Jaw (LF1212A), L-Hook (LF5637, LF5644) and XP Maryland (LXMJ37, LXMJ44) for specific open and laparoscopic needs.

Generator compatibility

Most current nano-coated models are designed for the Covidien Valleylab FT10 and ForceTriad energy platforms, while some older Atlas models require a specific generator. Confirm compatibility with your equipment and always follow the manufacturer's instructions for use.

Ordering tips

The fastest way to reorder is by reference number: the four digits after "LF" identify the jaw style and shaft length, so match the number on your current box. Some sealers are sold individually and others by the box, so check the purchase unit on each product page before you add it to your cart.
