Device Story

EnSite™ X EP System is a catheter navigation and mapping system used in clinical EP labs by physicians. It processes signals from electrophysiology catheters to display 3D catheter position, cardiac electrical activity (waveform traces), and 3D isopotential/isochronal maps of cardiac chambers. The system constructs anatomical models by collecting and labeling points as the catheter moves within the heart. The subject device (v2.0.1) adds compatibility with the TactiFlex™ Ablation Catheter, Sensor Enabled™, providing user-selectable Force Number Refresh Rates and a Force Direction Indicator (arrows at catheter tip). These features assist clinicians in visualizing contact force and orientation during ablation procedures, potentially improving procedural precision and patient outcomes. The system integrates with TactiSys™ Quartz Equipment for force visualization.

Clinical Evidence

Bench testing only. Design verification activities, including software/system-level verification, preclinical validation, human factors evaluations, and electrical safety testing, confirmed the system meets user requirements and safety standards (IEC 62304, ISO 14971, ANSI AAMI IEC 62366-1, IEC 60601-1).

Technological Characteristics

Catheter navigation and mapping system; 3D cardiac modeling; software-based signal processing; connectivity with TactiSys™ Quartz Equipment; compatible with Sensor Enabled™ catheters. Standards: IEC 62304, ISO 14971, ANSI AAMI IEC 62366-1, IEC 60601-1.

Indications for Use

Indicated for patients undergoing electrophysiology studies. Provides cardiac electrical activity data and catheter visualization during conventional EP procedures.

| Device Description | The EnSite™ X EP System is a catheter navigation and mapping system. A catheter<br>navigation and mapping system is capable of displaying the 3-dimensional (3-D)<br>position of conventional and Sensor Enabled™ (SE) electrophysiology catheters, as<br>well as displaying cardiac electrical activity as waveform traces and as three-<br>dimensional (3D) isopotential and isochronal maps of the cardiac chamber.<br><br>The contoured surfaces of the 3D maps are based on the anatomy of the patient's<br>own cardiac chamber. The system creates a model by collecting and labeling the<br>anatomic locations within the chamber. A surface is created by moving a selected<br>catheter to locations within a cardiac structure. As the catheter moves, points are<br>collected at and between all electrodes on the catheter. A surface is wrapped around<br>the outermost points. |
