# 2.1. Device Description

The ACORYS MAPPING SYSTEM (ACORYS) is a non-invasive cardiac mapping system based on electrocardiographic imaging, that provides three-dimensional (3D) electroanatomic maps of the heart. It combines body surface potential measurements with a 3D model of the torso to generate panoramic, bi-atrial and/or bi-ventricular 3D electroanatomic maps.

# System components:

The ACORYS MAPPING SYSTEM is comprised of the following components:

1. ACORYS Sensor Vest (ACSEN): High density sensor array for the acquisition of surface electrocardiographic signals. ACSEN is a type-CF applied part.
2. ACORYS Amplifier (ACAMP): Module used to amplify and digitalize the signals acquired from the patient's torso. ACAMP includes two extra submodules, ACTRA and ACCABx defined as follows:

2.1. ACORYS Isolation transformer (ACTRA): Medical degree isolation transformer to charge the internal batteries of the amplifier.
2.2. ACORYS Connector Cables (ACCAB_L and ACCAB_R): Elements to transmit the electrical signals acquired by the sensor vest to the amplifier. ACCAB_L and ACCAB_R are type CF applied parts.

3. ACORYS Software (ACSOF): Software for signal analysis. The results of the said analysis are displayed as electroanatomic maps that allow the evaluation of the electrical activity on the surface of the heart. ACSOF is installed on a workstation that is connected to the amplifier via ACORYS Isolation Ethernet (ACNET), an ethernet isolator 60601 compliant.
4. ACORYS 3D Scan Software (ACSCAN): Module for the 3D reconstruction of the patient's torso.

Additionally, the ACORYS software operates on commercially available general-purpose hardware components provided as part of the system:

Workstation: The ACSOF module operates on a workstation running a compatible which provides the computing environment required for data processing, visualization, and analysis. Standard peripherals such as a monitor, keyboard, and mouse may be used.

3D Scan Platform: The ACSCAN module operates on a tablet-based platform that integrates a compatible 3D sensor for anatomical acquisition. This platform enables 3D torso reconstruction and electrode localization for subsequent processing within the ACORYS system.

## Performance Testing – Bench

Mathematical modeling was implemented to assess the effect of each existing technological differences with respect to the predicate device in the performance of our system. No adverse impact on mapping accuracy was observed due to the differences; indeed, the ACORYS configuration yielded equivalent or improved localization accuracy in mathematical simulation.

## Performance Testing - Clinical

Clinical evaluation was conducted to demonstrate that the performance and safety of the subject device, the ACORYS MAPPING SYSTEM, is substantially equivalent to that of the proposed predicate device, the Medtronic’s CardioInsight system (K162440). The system was evaluated in a multicenter clinical investigation conducted in three hospitals in Spain, including 199 patients with different arrhythmia types. The primary objective of the study was to evaluate the accuracy of the positive predictive value of the new ECGI system in identifying the relevant arrhythmic region and/or the correct placement of a pacemaker/defibrillator device.
