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.1FMX 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

- Shinkawa, T., Holloway, J., Tang, X., Gossett, J., Imamura, M.; A ferromagnetic surgical system reduces phrenic nerve injury in redo congenital cardiac surgery. Interact CardioVasc Thorac Surg 2017; 24 (5): 802-803. doi: 10.1093/icvts/ivw444 – A ferromagnetic surgical system (FMwand) is a new type of dissection device expected to reduce the risk of adjacent tissue damage. We reviewed 426 congenital cardiac operations with cardiopulmonary bypass through redo sternotomy to assess if this device prevented phrenic nerve injury.
- Starr, J., Gates, R., Palafox, B., Quill, A.; Retrospective Cohort Study Comparing Redo Operations Using Ferromagnetic Dissection and Conventional Monopolar Dissection. Surgical Innovation Vol 23, Issue 5, pp. 511 – 514 – To evaluate effectiveness of a novel hemostatic dissection tool in patients with congenital heart disease undergoing redo pericardiac dissections. This dissection tool employs ferromagnetic energy to cut and coagulate. The unit passes no electric current through the patient, thus eliminating cautery-induced dysrhythmias and electrical interference. Ferromagnetic dissection is precise and reduces thermal injury spread by as much as 90%.
- Weiss, J. Peter Manwaring, Preston et al. Freedom from electromagnetic interference between cardiac implantable electronic devices and the FMwand ferromagnetic surgical system. Journal of Clinical Anesthesia , Volume 25 , Issue 8 , 681 – 684 – The use of electrosurgical cutting tools has become almost ubiquitous in the modern operating room and medical procedure suite. These devices are intended to give physicians the ability to precisely dissect tissue (similar to a traditional scalpel) with the additional benefit of better bleeding control during and after procedures. One characteristic of many of the devices, particularly those utilizing monopolar energy delivery, is their transmission of electrical current through the patient as energy is delivered from the cutting instrument, through the patient’s tissue, to a grounding electrode.
