Stereotaxis Inc. is an American publicly traded corporation based in St. Louis, Missouri, that makes robotic products to try to improve the clinical outcomes of electrophysiology studies.

The Niobe Es Magnetic Navigation System includes two pods that use permanent magnets mounted on pivoting arms and positioned on opposing sides of the operating table.

[1] The magnets are controlled by physicians from the outside using[2] a mouse, keyboard, joystick, and[3] a viewing screen.

The rotation of the magnets within the Niobe pods influences the magnetic catheters in the heart to make micro movements of the catheter tip (in increments of 1 mm to 9 mm) to navigate throughout the four chambers of the heart.

[4][5][1][6] The RMN system was originally designed for applications within the brain; its current usage is guiding magnetic catheters during electrophysiology studies and catheter ablation procedures to treat arrhythmias in the heart.
