Intended Use

The Ensite® Multi-electrode Diagnostic Catheter used with the Ensite 3000 Electrophysiology Workstation is intended to be used in the right atrium of patients with complex arrhythmias that may be difficult to identify using conventional mapping systems alone (i.e., linear mapping catheters).

Device Story

EnSite 3000 System is a computerized electrophysiology (EP) mapping system. It consists of a console workstation, patient interface unit, and a multi-electrode diagnostic catheter. Unlike conventional catheters, the EnSite catheter does not require direct endocardial contact to detect intracardiac electrograms. The system uses proprietary software algorithms to reconstruct and display right atrial electrograms as color-coded 3D maps, providing global electrical activation patterns. It also includes a navigational tool for real-time feedback on auxiliary catheter positioning to create geometrical models of heart chambers or guide therapy. Used in clinical EP settings by physicians; the system integrates with standard mapping catheters, cardiac stimulators, and ECG leads. By visualizing complex activation patterns, it assists clinicians in identifying arrhythmia substrates, potentially improving diagnostic accuracy for complex cases.

Clinical Evidence

Bench testing only. The device underwent a battery of bench and user tests conducted in accordance with in-house procedures to validate the modifications. No clinical trial data was provided.

Technological Characteristics

System includes a multi-electrode diagnostic catheter and an EP workstation. Employs non-contact electrogram detection technology. Features 3D mapping software and real-time navigational tools for auxiliary catheter tracking. Connectivity includes analog/digital inputs for ECG leads and cardiac stimulators. Software-based reconstruction of electrical signals.

Indications for Use

Indicated for patients with complex cardiac arrhythmias requiring mapping in the right atrium that are difficult to identify using conventional linear mapping catheters.

Regulatory Classification

Identification

An electrode recording catheter or an electrode recording probe is a device used to detect an intracardiac electrocardiogram, or to detect cardiac output or left-to-right heart shunts. The device may be unipolar or multipolar for electrocardiogram detection, or may be a platinum-tipped catheter which senses the presence of a special indicator for cardiac output or left-to-right heart shunt determinations.

The system consists of a console workstation, patient interface unit, and an electrophysiology mapping catheter. Unlike currently available electrode recording catheters, the EnSite Catheter does not require direct contact with the endocardium for the detection of intracardiac electrograms. The EnSite 3000 Electrophysiology Workstation connected to the EnSite Catheter utilizes proprietary software algorithms to reconstruct and display right atrial electrograms detected by the EnSite Catheter. This information can be presented as color-coded three-dimensional maps to provide global electrical activation patterns of the heart

chamber. The EnSite 3000 System may also be used in conjunction with standard electrode mapping catheters, programmable cardiac stimulators, ECG leads, and other analog or digital inputs.

The EnSite 3000 System also incorporates a navigational tool to provide real-time feedback regarding the position of an auxiliary catheter for creation of a geometrical model of the heart chamber or for guiding therapy to a designated location.

## Intended use:

The EnSite Multi-electrode Diagnostic Catheter used with the EnSite 3000 Electrophysiology Workstation is intended to be used in the right atrium of patients with complex arrhythmias that may be difficult to identify using conventional mapping systems alone (i.e., linear mapping catheters).

## Technological Characteristics:

The new device has the same technological characteristics as the legally marketed predicate device.

# Non-clinical performance data:

The changes made to the EnSite 3000 System underwent a battery of bench and user tests. Device validation testing was conducted in accordance with in-house procedures.

## Conclusion:

An evaluation of the device changes indicates that the device is as safe and effective as the previously marketed device to which it is being compared and does not raise any new issues of safety and effectiveness.
