Magbot Magnetic Navigation Ablation Catheter

Magbot is a single-use magnetic saline-irrigated radiofrequency ablation catheter co-developed by MicroPort EP and Stereotaxis. Designed exclusively for robotic magnetic navigation systems, the catheter received NMPA approval in December 2024.

Product Overview

The Magbot catheter represents the result of collaboration between MicroPort EP’s catheter engineering expertise and Stereotaxis’ robotic navigation technology. Unlike conventional manual catheters, Magbot is purpose-built to work with the Genesis RMN robotic platform, enabling robotically-controlled navigation and positioning during cardiac ablation procedures.

The catheter uses low-intensity magnetic fields for guidance rather than mechanical push-pull forces, allowing access to cardiac regions that may be difficult to reach with traditional catheter manipulation techniques.

Key Features

For cardiac arrhythmia ablation, Magbot’s magnetic navigation tip enables millimeter-level catheter positioning within Genesis RMN robotic systems.

• Magnetic Navigation Compatible: Designed specifically for Genesis RMN robotic control
• Irrigated RF Ablation: Saline irrigation for tissue cooling during energy delivery
• Columbus Integration: Full compatibility with MicroPort EP’s 3D navigation system for real-time tracking
• Precise Positioning: Millimeter-level accuracy in catheter tip placement
• Stable Contact: Magnetic control maintains consistent tissue contact during lesion formation
• Single-Use Design: Sterile, disposable catheter for each procedure

Technical Specifications

Magbot’s saline-irrigated RF design pairs with Columbus 3D tracking and requires Genesis RMN magnetic field control for single-use procedures.

Clinical Applications

Magbot enables robotic ablation procedures for:

• Atrial Fibrillation: Pulmonary vein isolation with precise circumferential lesion sets
• Atrial Flutter: Cavotricuspid isthmus ablation
• Complex Arrhythmias: Access to anatomically challenging locations
• Repeat Procedures: Navigation in scarred tissue from prior ablations

The robotic approach reduces procedure variability and operator dependence, potentially improving lesion quality consistency.

System Requirements

Magbot operates as part of an integrated robotic electrophysiology workflow:

The catheter cannot be used independently of the Genesis RMN system due to its magnetic navigation design.

Regulatory Status

Magbot represents a China-first product launch, with MicroPort EP leading commercial introduction through its domestic electrophysiology sales network.

Frequently Asked Questions

Can Magbot be used without the Genesis RMN system?

No. Magbot is designed exclusively for magnetic navigation and requires the Genesis RMN robotic platform for catheter control. It cannot be manipulated manually like conventional ablation catheters.

How does Magbot differ from FireMagic catheters?

FireMagic is MicroPort EP’s manual ablation catheter line with magnetic tracking for Columbus visualization. Magbot is robotically-navigated and requires the Genesis RMN system for control. FireMagic can be used in conventional manual procedures; Magbot cannot.

What is the relationship between MicroPort EP and Stereotaxis for Magbot?

Magbot was co-developed by both companies under their 2021 partnership agreement. MicroPort EP manufactures and commercializes the catheter in China, with Stereotaxis sharing in adoption proceeds.

Is training required to use Magbot?

Yes. Physicians must be trained on both the Genesis RMN robotic system and specific Magbot catheter handling protocols. MicroPort EP provides training programs in conjunction with Genesis system installation.
