Genesis RMN System
Genesis RMN represents Stereotaxis’ third-generation robotic magnetic navigation platform, designed to provide physicians with unprecedented precision and responsiveness when performing cardiac ablation procedures. The system received NMPA approval in November 2024 through Stereotaxis’ partnership with MicroPort EP Medtech in China.
Product Overview
Building on over two decades of clinical experience with earlier Niobe systems, Genesis introduces novel smaller magnets held on flexible robotic arms that rotate along their center of mass. This architecture delivers instantaneous responsiveness to physician control while accommodating an increased range of motion compared to previous generations.
Genesis enables physicians to navigate magnetically-compatible catheters through the heart’s chambers with 1mm/1° precision—accuracy levels unachievable through manual catheter manipulation. The remote operation model allows physicians to perform procedures from a protected cockpit, reducing radiation exposure while maintaining complete procedural control.
Key Features
Approved in China in November 2024 through MicroPort EP, Genesis RMN’s flexible robotic arms position smaller magnets at 1 mm/1° precision for cardiac ablation from a radiation-protected cockpit.
- Flexible Robotic Arms: Novel magnet positioning system provides greater angulation range and improved imaging access
- Instantaneous Response: Advanced electronics deliver immediate catheter response to control inputs
- Reduced Footprint: Significant size reduction compared to Niobe improves patient experience and staff access
- Remote Operation: Physician-controlled from a seated position in a radiation-protected cockpit
- Integration Ready: Compatible with third-party mapping systems including Abbott’s and MicroPort EP’s Columbus

Clinical Applications
Genesis supports catheter ablation procedures for treating:
Atrial Fibrillation (AFib): The most common indication, Genesis enables precise pulmonary vein isolation and complex atrial substrate ablation with consistent tissue contact.
Ventricular Tachycardia (VT): RMN technology reaches scar-related arrhythmogenic substrates that may be inaccessible to manual catheters.
Complex Congenital Heart Disease: Navigating unusual anatomy in patients with structural heart abnormalities where traditional catheter approaches often fail.
Accessory Pathway Ablation: Treating WPW syndrome and other accessory pathway-mediated arrhythmias with high precision.
Multiple meta-analyses have linked RMN procedures to lower complication rates and reduced fluoroscopy time compared to manual navigation approaches.
Regulatory Status
| Region | Status | Date |
|---|---|---|
| China (NMPA) | Approved | November 2024 |
| European Union (CE) | Marked | 2019 |
| United States (FDA) | Cleared | Yes |
In China, Genesis is distributed exclusively by MicroPort EP Medtech, which initiated full commercial launch following NMPA approval. The system integrates with MicroPort EP’s Columbus 3D mapping system for full procedural visualization.
Installation Considerations
Genesis requires a dedicated electrophysiology lab with magnetic shielding incorporated into the room structure. Installation involves:
- Room construction/modification for magnetic shielding
- Equipment installation by Stereotaxis technicians
- Staff training program
- System calibration and validation
For facilities seeking faster deployment without room modification, Stereotaxis offers the GenesisX platform as an alternative.
Frequently Asked Questions
What is the Genesis RMN System used for?
Genesis performs radiofrequency cardiac ablation procedures to treat heart rhythm disorders including atrial fibrillation, ventricular tachycardia, and supraventricular tachycardia. The magnetic navigation enables precise catheter positioning in complex cardiac anatomy.
How does Genesis differ from the older Niobe system?
Genesis uses smaller magnets on flexible robotic arms providing faster response times and greater range of motion. The reduced system size improves patient access during procedures while maintaining the proven safety and efficacy of RMN technology.
Is Genesis RMN available in China?
Yes, Genesis received NMPA approval in November 2024 and is commercially available through MicroPort EP Medtech’s nationwide sales network.
