ORION-1 EMF System Features The Orion-1 EMF from Ortho Development is like no other electrosurgical device you’ve used before. The Orion-1 EMF is the first and only neurosurgical device that uses extremely high radio frequency (13.86 MHz) and low power (16.9 watts) to achieve instantaneous pin-point vaporization. No grounding pad is required. Procedures around critical areas can be performed with greater accuracy and safety. As a result, the Orion-1 EMF is ideal for precise vaporization of dense, woody cranial tumors. The thermal spread is less than 1 mm. Idea for precise vaporization No grounding pad is required Less than 1mm spread Uses high radio frequency and low power ORION-1 EMF System Specifications Dimensions Height: 16-Inches Depth: 10-Inches Width: 17-Inches Weight: 38 Lbs
