Covidien LigaSure Vessel Sealing Devices: Types, Uses & Buyer’s Guide

Covidien LigaSure™ vessel sealing devices are advanced bipolar electrosurgical instruments designed to seal vessels and tissue bundles during surgical procedures. Today part of the Medtronic surgical energy portfolio, LigaSure technology is used across a wide range of open and minimally invasive procedures.

The LigaSure family includes multiple instrument styles designed for different surgical approaches, tissue types and procedural requirements. Options include LigaSure Small Jaw, Exact Dissector, Impact, Blunt Tip, Maryland Jaw, XP Maryland Jaw, Thoracic Maryland Jaw and laparoscopic L-Hook instruments.

For hospitals, ambulatory surgery centers and surgical practices purchasing LigaSure instruments, understanding the differences between these devices can help identify the appropriate product and manufacturer catalog number for a facility's existing equipment and procedural needs.

What Is LigaSure?

LigaSure is a bipolar vessel sealing technology used for ligation and division of vessels, tissue bundles and lymphatics.

Unlike a basic electrosurgical instrument, LigaSure technology applies energy together with controlled pressure to create a vessel seal. Many LigaSure instruments also incorporate a cutting mechanism, allowing the surgeon to seal and divide tissue with the same device.

Depending on the instrument, LigaSure devices may be designed for open surgery, laparoscopic surgery or specialty procedures.

What Is the Difference Between Covidien and Medtronic LigaSure?

Healthcare buyers may encounter both the Covidien and Medtronic names when searching for LigaSure products.

LigaSure was historically marketed under Covidien. Following Medtronic's acquisition of Covidien, LigaSure became part of the Medtronic surgical energy portfolio.

As a result, purchasing departments may search for these products using terms such as:

  • Covidien LigaSure

  • Medtronic LigaSure

  • LigaSure vessel sealer

  • LigaSure sealer/divider

  • LigaSure handpiece

  • LigaSure surgical instrument

  • LigaSure disposable

  • LigaSure vessel sealing device

When purchasing replacement instruments, the manufacturer catalog number is one of the best ways to confirm the exact product required.

Types of LigaSure Vessel Sealing Devices

Because LigaSure is a vessel sealing platform rather than a single surgical instrument, its applications span numerous surgical specialties.

Depending on the specific LigaSure model and its indications for use, potential users include:

General Surgery

General surgeons may use compatible LigaSure instruments in procedures involving tissue dissection, vessel sealing and division.

Colorectal Surgery

LigaSure instruments are used in colorectal procedures where surgeons may need to dissect tissue and seal vessels during bowel surgery.

Gynecologic Surgery

Gynecologic surgeons may use LigaSure vessel sealing instruments during open or laparoscopic procedures where vessel and tissue bundle sealing is required.

Urologic Surgery

Certain LigaSure devices are indicated for urologic surgical procedures and may be purchased by hospitals and urology surgery programs.

Thoracic Surgery

Specialized LigaSure instruments, including the Maryland Jaw Thoracic device, are designed for thoracic applications.

ENT and Head & Neck Surgery

Certain open LigaSure instruments are indicated for ENT procedures, including applications associated with thyroid, neck and parotid surgery.

Vascular Surgery

Specific LigaSure devices may also be used within vascular surgical applications according to their individual indications for use.

Who Buys LigaSure Instruments?

For medical supply purchasing, knowing the end user is just as important as knowing the product.

The primary institutional buyers for Covidien and Medtronic LigaSure instruments include:

  • Acute-care hospitals

  • Thoracic surgery programs

Within these organizations, purchasing decisions may involve OR managers, materials managers, surgical supply buyers, procurement specialists, supply chain directors, value-analysis committees and surgeons.

What Should Buyers Check Before Ordering LigaSure?

LigaSure instruments are not interchangeable simply because they use the same vessel sealing technology.

Before purchasing, verify:

  • Manufacturer catalog number

  • Open vs. laparoscopic configuration

  • Shaft length

  • Jaw style

  • Instrument diameter

  • Seal and cut configuration

  • Generator compatibility

  • Package quantity

  • Facility preference or surgeon preference card

  • Current manufacturer instructions for use

Generator compatibility is especially important. Different LigaSure products may specify compatibility with platforms such as the Valleylab™ FT10 energy platform, Valleylab LS10 generator or ForceTriad™ energy platform, depending on the instrument.

The exact manufacturer catalog number should be verified before substituting one LigaSure instrument for another.

Frequently Asked Questions

Is LigaSure made by Covidien or Medtronic?

LigaSure was historically sold under the Covidien brand. Covidien became part of Medtronic, and LigaSure is now included within Medtronic's surgical energy portfolio. Buyers may therefore encounter both Covidien and Medtronic names when searching for LigaSure instruments.

What does a LigaSure device do?

LigaSure technology uses bipolar electrosurgical energy and pressure to seal vessels and tissue bundles. Many LigaSure instruments also incorporate a cutting mechanism that allows sealed tissue to be divided with the same instrument.

Are all LigaSure devices the same?

No. LigaSure instruments differ in jaw design, shaft length, diameter, surgical approach and other specifications. Some are designed for open procedures while others are designed for laparoscopic or specialty applications.

What is the difference between LigaSure Maryland Jaw and Blunt Tip?

The Maryland Jaw family uses a curved Maryland-style jaw designed to facilitate access and vessel dissection. LigaSure Blunt Tip devices use a blunt double-action jaw with contoured tips. The appropriate choice depends on the procedure, surgeon preference and the manufacturer's indications for use.

What is the difference between LigaSure Impact and Small Jaw?

LigaSure Impact uses a comparatively large curved jaw and longer sealing surface, while the Small Jaw instrument provides a more compact open-surgery configuration. Facilities should select the exact instrument specified by the surgeon or procedure requirements.

Are LigaSure instruments reusable?

Many commonly purchased LigaSure hand instruments are sterile, single-use devices. Buyers should verify the manufacturer's instructions for the specific catalog number because the LigaSure portfolio includes different instrument configurations and components.

How do I find the correct replacement LigaSure instrument?

The safest purchasing method is to locate the manufacturer catalog number from the existing product packaging, surgeon preference card or facility inventory system. Search that catalog number rather than relying solely on the term "LigaSure."
