Cardiothoracic

OmniGuide's electrically silent advanced energy gives you the confidence to operate directly on or near the heart and other delicate structures in a variety of cardiothoracic procedures.1

FMX Ferromagnetic Technology in Cardiothoracic Surgery

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 organs, including the heart. Surgeons and anesthesiologists report no generation of dysrhythmia when using FMX instruments.1

Precise Dissection
  • Produces a precise, surface-only thermal effect with tactile control and minimal tissue drag
  • Clean dissection results in superior visualization of distinct tissue planes
  • Effective dissection through dense adhesions
  • Fewer incidents of damage to the phrenic nerve2
Minimized Thermal Injury
  • As little as 1/10th the thermal injury compared to monopolar electrosurgery1,3
  • As few as 80 microns (0.08 mm) of thermal spread in some tissue types1,3
  • Less unintended damage to tissue, resulting in reduced bleeding and need for re-exploration4
  • Less post-operative drainage4
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 the FMwand report no interference with electrophysiological monitoring, ultrasound imaging, cochlear implants, or Cardiac Implantable Electronic Devices (CIEDs)1,5
  • FMX Generator has Type CF (“Cardiac Floating”) rating
FMX Clinical Applications
  • Congenital heart repair*
  • Valve repair/replacement*
  • Ventricular assist device implant/explant*
  • Coronary artery bypass graft*
  • Transplant*
  • Lung decortication*
  • Any re-operative procedure*
