MAGiC Sweep High-Density Mapping Catheter

MAGiC Sweep is Stereotaxis’ robotically navigated high-density electrophysiology mapping catheter, featuring 20 electrodes for rapid and detailed electroanatomical mapping. As the first robotic HD mapping catheter, MAGiC Sweep combines the precision benefits of magnetic navigation with modern multi-electrode technology.

Product Overview

Electroanatomical mapping forms the foundation of cardiac ablation procedures, creating detailed 3D maps of electrical activity to identify arrhythmia sources and guide treatment. MAGiC Sweep accelerates this process by collecting data from 20 electrodes simultaneously while maintaining the inherent safety advantages of Stereotaxis’ atraumatic catheter design.

Traditional rigid HD mapping catheters can distort anatomy during contact, potentially affecting map accuracy. MAGiC Sweep’s flexible shaft and magnetic navigation avoid this issue while reaching complex anatomical structures that rigid catheters may struggle to map completely.

Key Features

MAGiC Sweep’s 20-electrode robotic mapping catheter cleared FDA in July 2025, letting electrophysiologists map complex cardiac anatomy without the tissue distortion of rigid catheters.

• 20-Electrode Array: Simultaneous data collection from multiple electrodes enables rapid, high-resolution mapping
• Robotic Navigation: Magnetic control from the tip provides precise positioning throughout cardiac chambers
• Atraumatic Design: Flexible construction eliminates anatomic distension caused by rigid catheters
• Spatial Memory: Precise, repeatable positioning for accurate point-by-point mapping
• Complex Anatomy Access: Navigates to positions often unreachable by conventional catheters
• Reduced Mapping Time: Multi-electrode collection accelerates the mapping phase

Technical Specifications

MAGiC Sweep is a 20-electrode, atraumatic mapping catheter requiring Stereotaxis Genesis or GenesisX robotic platforms and compatible with major 3D mapping systems.

Clinical Applications

Pre-Ablation Mapping: Creates detailed electroanatomical maps identifying arrhythmia mechanisms and optimal ablation targets before treatment begins.

Complex Substrate Mapping: Detailed characterization of scar and abnormal tissue in patients with structural heart disease or prior ablation.

Congenital Heart Disease: Maps unusual anatomy in patients with structural cardiac anomalies where traditional catheters may provide incomplete coverage.

Activation and Voltage Mapping: High-density data supports both activation sequence analysis and voltage-based substrate identification.

Regulatory Status

First US commercial robotic HD mapping procedures were completed successfully in September 2025, demonstrating the clinical viability of magnetically-navigated high-density mapping.

Procedural Workflow

MAGiC Sweep integrates into the standard Stereotaxis ablation workflow:

1. Initial Access: Catheter advanced to cardiac chambers via femoral venous approach
2. Robotic Activation: Physician assumes control from Navigant workstation
3. Systematic Mapping: 20-electrode array collects data as catheter is navigated throughout chambers
4. Map Generation: Real-time 3D electroanatomical map created in integrated mapping system
5. Ablation Planning: Map guides subsequent ablation with MAGiC catheter

The flexible shaft maintains stability during mapping without the cardiac motion artifacts that can affect data quality with rigid catheters.

Comparison with Manual HD Mapping

Frequently Asked Questions

What is high-density mapping?

High-density (HD) mapping uses catheters with multiple electrodes to collect detailed electrical information about the heart, creating precise 3D maps that guide ablation therapy. MAGiC Sweep’s 20 electrodes enable faster, more detailed maps than traditional single-electrode approaches.

Can MAGiC Sweep be used without a Stereotaxis robot?

No, MAGiC Sweep requires a Stereotaxis Genesis or GenesisX robotic magnetic navigation system for catheter control. It cannot be used manually.

How does MAGiC Sweep differ from the MAGiC ablation catheter?

MAGiC Sweep is designed for mapping (diagnosis) with 20 recording electrodes, while MAGiC is designed for ablation (treatment) with radiofrequency energy delivery capability. Both use robotic magnetic navigation but serve different procedural functions.
