FMX Generator

Surgical precision. Electrical silence.

Domain Surgical’s FMX™ Ferromagnetic Surgical System is an intelligent surgical platform that uses ferromagnetic technology to precisely cut, coagulate, and seal tissue; with a fraction of tissue injury compared to other surgical technologies, and without passing electrical current through the patient.

FMX Generator

The FMX Generator intelligently manages all aspects of energy, ensuring that the optimal amount of heat is delivered to the tissue at all times. Learn more about the FMX Generator.

FMX Surgical Instruments

A variety of dissection and vessel sealing instruments have been developed for use in both open and laparoscopic surgical procedures. View FMX surgical instruments.

FMX Power Modules

FMX Power Modules connect FMX surgical instruments to the generator and  manage communication between each component. Learn more about FMX Power Modules.

FMX Generator

The FMX Generator intelligently manages all aspects of energy, ensuring that the optimal amount of heat is delivered to the tissue at all times.

The FMX Generator intelligently delivers electrical energy to the surgical instruments. The advanced generator features a patented software control algorithm that continuously monitors and adjusts the delivery of energy, ensuring that the optimal amount of heat is delivered to the tissue at all times. The large touchscreen display provides the entire surgical team immediate feedback on power setting levels and changing settings is as easy as touching the display. The FMX Generator has earned the Type CF (“Cardiac Floating”) rating.

FMX Surgical Instruments

A variety of dissection and vessel sealing instruments have been developed for use in both open and laparoscopic surgical procedures.

FMwand Dissector

FMwand is a thermal dissection instrument that precisely cuts and coagulates with less tissue injury compared to traditional technologies, without passing electrical current through the patient.

FMsealer Open Shears

FMsealer Open Shears

FMsealer Open Shears reliably seal and transect vessels and vascular tissue bundles with a pure thermal effect. FMsealer Open Shears are indicated for sealing lymphatics and vessels up to 7mm in diameter in open procedures.

FMsealer Laparoscopic Shears

FMsealer Laparoscopic Shears

FMsealer Laparoscopic Shears provide surgeons with precise control of thermal effect for fast, reliable sealing and transection of vessels and vascular tissue bundles. FMsealer Laparoscopic Shears are indicated for sealing of lymphatics and vessels up to 7mm in diameter in open and laparoscopic procedures.

FMX Power Modules

FMX Power Modules connect FMX surgical instruments to the generator and manage communication between each component.

FMX Power Modules FMX Power Modules are available in both reusable and single-use disposable configurations. The FMX Reusable Power Module (left) can be autoclave resterilized for use in up to 100 procedures, providing a cost-effective option for the hospital. The FMX Disposable Power Module (right) is single-use only and is discarded following each surgical procedure.

How FMX Technology Works

FMX ferromagnetic technology creates a localized layer of heat around the tip of each surgical instrument, which provides a uniform thermal tissue effect when cutting, coagulating, and sealing tissue.
FMX How It Works Step 1

The active surface of each FMX surgical instrument is plated with a thin ferromagnetic coating. When the instrument is activated, the FMX generator passes high frequency electrical energy through the ferromagnetic coating and back to the generator, creating a rapidly alternating magnetic field within the coating.

FMX How It Works Step 2

The coating instantly reacts to the alternating magnetic field, producing uniform heat throughout the coated area. When in contact with tissue, this uniform heat precisely cuts, coagulates, and seals with minimal collateral thermal injury.

FMX How It Works Step 3

FMX surgical instruments are electrically silent; meaning that the electrical energy delivered to each instrument returns to ground through the generator and does not pass through the tissue. No grounding pad is used, and there is no spark, arcing, or stray current that can injure delicate structures.

Because heat is generated only in the area plated with the ferromagnetic coating, FMX surgical instruments activate instantly and cool down in seconds. FMX technology provides extremely precise and predictable control of thermal effect and reduces thermal injury to deeper tissue and surrounding structures; while eliminating the passage of potentially dangerous electrical current through the patient.

Setup is Incredibly Simple

The FMX Ferromagnetic Surgical System combines state-of-the-art surgical technology with unparalleled ease-of-use. Prepare FMX instruments for use by following these simple steps:

1

Plug the FMX Power Module into the front panel of the FMX Generator

2

Snap the power module into the back of the FMX instrument

3

Set the power settings on the generator and the system is ready
