Genesis RMN Robotic Magnetic Navigation System
Genesis RMN (Robotic Magnetic Navigation) is a surgical robotics platform developed by Stereotaxis (NYSE: STXS) for minimally invasive cardiac catheter ablation procedures. MicroPort EP serves as the exclusive distributor in China, where the system received NMPA approval in November 2024.
Product Overview
The Genesis system uses externally generated low-intensity magnetic fields to precisely navigate specialized catheters within cardiac chambers. Unlike mechanically-driven robotic systems, magnetic navigation enables soft, flexible catheter control that conforms to cardiac anatomy while maintaining stable tissue contact during ablation.
The partnership between Stereotaxis and MicroPort EP, announced in August 2021, encompasses development, integration, and commercialization of the robotic platform alongside MicroPort EP’s Columbus 3D mapping system and Magbot navigation catheter.
Key Features
Genesis RMN is a Stereotaxis-developed cardiac ablation robot distributed exclusively in China by MicroPort EP since its NMPA approval in November 2024, using low-intensity magnetic fields for sub-millimeter catheter positioning.
- Magnetic Field Navigation: Low-intensity magnetic fields guide catheter positioning without mechanical push/pull forces
- Sub-Millimeter Precision: Robotically-controlled tip positioning with millimeter-level accuracy
- Stable Tissue Contact: Soft magnetic navigation maintains consistent lesion formation
- Complex Anatomy Access: Reaches cardiac regions difficult to access with manual catheter manipulation
- Reduced Radiation: Decreased fluoroscopy time compared to conventional manual procedures
- Columbus Integration: Real-time 3D visualization through MicroPort EP’s navigation system
Technical Specifications
External magnetic field navigation positions compatible catheters to millimeter-level accuracy; the Columbus 3D EP system and Magbot catheter form an integrated workflow for Chinese hospitals.
| Parameter | Specification |
|---|---|
| Navigation Method | External magnetic field |
| Positioning Accuracy | Millimeter-level |
| Compatible Systems | Columbus 3D EP Navigation System |
| Compatible Catheters | Magbot, magnetically-enabled catheters |
| Procedure Types | Cardiac ablation, complex arrhythmia |
Clinical Applications
Genesis RMN addresses complex cardiac ablation cases where conventional manual catheter navigation faces limitations:
- Atrial Fibrillation: Persistent and long-standing persistent AF with complex anatomy
- Ventricular Tachycardia: Substrate ablation in challenging locations
- Congenital Heart Disease: Navigation in altered anatomical structures
- Repeat Ablation Procedures: Cases with scar tissue and modified anatomy
The robotic approach reduces operator fatigue during lengthy procedures and provides reproducible catheter positioning independent of physician hand stability.
Regulatory Status
| Region | Status | Date |
|---|---|---|
| China (NMPA) | Approved | November 2024 |
| European Union (CE) | Approved | Yes |
| United States (FDA) | Cleared | Yes |
Genesis has treated thousands of patients in the United States and Europe prior to China market entry.
System Integration
In China, Genesis RMN operates as part of an integrated workflow:
- Columbus 3D EP Navigation: Provides anatomical mapping and real-time catheter visualization
- Genesis RMN: Delivers robotic magnetic field control for catheter navigation
- Magbot Catheter: Purpose-designed magnetic navigation ablation catheter
This integrated approach represents MicroPort EP’s strategy to offer complete robotic electrophysiology solutions domestically.
Frequently Asked Questions
Who manufactures Genesis RMN?
Genesis RMN is developed and manufactured by Stereotaxis, a US-based medical robotics company. MicroPort EP holds exclusive distribution rights in China and collaborates on compatible catheter development.
How does magnetic navigation differ from mechanical robotic systems?
Mechanical systems (like da Vinci) use rigid instruments with motorized joints. Magnetic navigation uses external magnets to guide flexible catheters, providing softer tissue interaction suitable for cardiac chambers where rigid instruments pose perforation risks.
What training is required for Genesis RMN?
Physicians require specialized training in magnetic navigation techniques. MicroPort EP provides training programs through its existing electrophysiology sales and education teams in China.
Can Genesis RMN be used for non-cardiac procedures?
The Genesis platform is specifically designed for cardiac electrophysiology applications. Stereotaxis has explored vascular applications, but the China approval through MicroPort EP focuses on cardiac arrhythmia treatment.
