FMX Ferromagnetic Technology in Surgical Oncology

Domain Surgical’s FMX Ferromagnetic Surgical System 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. Because no electrical current passes through the patient, FMX surgical instruments can be used safely near nerves, vessels, and other delicate tissue structures. Predictable, char-free layer-by-layer dissection results in optimal visualization of tissue planes, and provides clear margins for reliable pathology specimens.

Precision
  • FMwand dissector produces a precise, surface-only thermal effect with tactile control and minimal tissue drag
  • Clean dissection when using the FMwand results in superior visibility and clear margins for reliable pathology specimens
Minimized Thermal Injury
  • FMwand produces as little as 1/10th the thermal injury compared to monopolar electrosurgery1,2
  • FMwand imparts as few as 80 microns (0.08 mm) of thermal spread in some tissue types1,2
  • FMsealer produces a pure thermal effect with less lateral thermal spread than competitive bipolar and ultrasonic devices1,4
Efficient and Robust Vessel Sealing
  • FMsealer delivers reliable vessel sealing performance and burst pressure measurements comparable to or better than industry-leading bipolar devices1,4
  • FMsealer delivers extremely fast and efficient sealing/dividing cycles through vascular tissue bundles, including in tough adhesions and scar tissue1,4
Electrical Silence
  • No electrical current passes through tissue – no grounding pad is used, and no spark, arcing, or stray current, no stimulation of muscles or nerves
  • Surgeons using FMX instruments report no interference with electrophysiological monitoring or cochlear implants1,3
