Intended Use

The AcQMap High Resolution Imaging and Mapping System is intended for use in patients for whom electrophysiology procedures have been prescribed. When used with the AcQMap Catheters, the AcQMap High Resolution Imaging and Mapping System is intended to be used to reconstruct the selected chamber from ultrasound data for purposes of visualizing the chamber anatomy and displaying electrical impulses as either charge density-based or voltage-based maps of complex arrhythmias that may be difficult to identify using conventional mapping systems alone. AND When used with the specified Patient Electrodes, the AcQMap High Resolution Imaging and Mapping System is intended to display the position of AcQMap Catheters and conventional electrophysiology (EP) catheters in the heart. OR When used with conventional electrophysiology catheters, the AcQMap High Resolution Imaging and Mapping System provides information about the electrical activity of the heart and about catheter location during the procedure.

Device Story

Computer-based diagnostic recording system for EP labs; images, navigates, and maps atrial chambers. Inputs: ultrasound data (for chamber reconstruction), ECG/EGM signals, and impedance-based electrode localization. Transforms inputs into 3D cardiac chamber reconstructions, catheter position displays, and dynamic charge density/voltage maps overlaid on anatomy. Operated by physicians in EP labs. Output: visual maps and waveform traces on workstation display. Assists physicians in identifying arrhythmia sources and guiding catheter placement. Benefits: enables visualization of complex arrhythmias difficult to identify with conventional systems alone; supports remapping during procedures.

Clinical Evidence

No new clinical testing performed. Relies on clinical data from the original AcQMap system (K170948) via the DDRAMATIC-SVT study: a prospective, non-randomized, open-label study of 84 patients conducted at eight clinical sites outside the U.S. to evaluate complex supraventricular tachycardia mapping.

Technological Characteristics

System components: Console, Workstation, Auxiliary Interface Box. Ultrasound imaging (10 MHz), ECG/EGM recording (0.05-500 Hz), impedance-based localization (15-50 kHz). Safety standards: IEC 60601-1, IEC 60601-1-2, IEC 62366-1, IEC 60601-2-25, IEC 60601-2-37. Class I, Type CF defibrillator-protected. Connectivity includes various adapter cables for ablation generators and catheters.

Indications for Use

Indicated for patients undergoing prescribed electrophysiology procedures. Used for reconstruction of cardiac chambers, visualization of anatomy, display of electrical impulses (charge density or voltage-based maps) for complex arrhythmias, and localization of EP catheters.

# Device Description [807.92(a)(4)]

The AcQMap High Resolution Imaging and Mapping System operates outside of the sterile field and consists of the AcQMap Console, the AcQMap Workstation and the AcQMap Auxiliary Interface Box.

The AcQMap High Resolution Imaging and Mapping System is a diagnostic recording system. This computer-based system is intended for use in the Electrophysiology (EP) Lab, and it is capable of imaging, navigation, and mapping of the atrial chambers of the heart.

The AcQMap High Resolution Imaging and Mapping System hardware consists of three functional subsystems:

- Ultrasound imaging,
- ECG and EGM recording; and
- Impedance based electrode Localization.

The AcQMap High Resolution Imaging and Mapping System is used in conjunction with the associated AcQMap 3D Imaging and Mapping Catheter models 900003 and 900009 (cleared under K201341). The AcQMap High Resolution Imaging and Mapping System provides:

- 3-D cardiac chamber reconstruction - Contact and non-contact (ultrasound),
- . Three-dimensional position of the AcQMap Catheter and conventional electrophysiology catheters,
- . Cardiac electrical activity as waveform traces,

The logo consists of the word "ACUTUS" in bold, black letters, with a small orange dot above the left side of the "A". Below the word "ACUTUS" is the word "MEDICAL" in smaller, orange letters. The logo is simple and modern, and the use of black and orange gives it a professional look.

- Contact LAT and voltage amplitude maps
- Remapping of the chamber at any time during the procedure; and
- Dynamic, three-dimensional, charge density maps overlaid on the cardiac chamber reconstruction ● to show chamber-wide electrical activation.

The AcQMap High Resolution Imaging and Mapping System is intended to create a surface reconstruction of the cardiac chamber as well as an electrical map of the substrate. The surface reconstruction and electrical map are then used by physicians to identify the source(s) of the arthythmia.

Additionally, the AcQMap High Resolution Imaging and Mapping System allows physicians to perform traditional contact mapping activities, including establishing a coordinate system, localizing conventional electrophysiology catheters relative to one another within the coordinate system, recording contact electrograms, and initiating a procedure without the AcOMap Catheter present. Based on the information captured in the contact electrograms, the physician may decide to treat an arrythmia without deploying the AcQMap Catheter.

The modifications to the AcQMap High Resolution Imaging and Mapping System include software modification and the addition of new accessories to support compatibility with the AcQBlate Force Sensing Ablation System.

# Indications for Use [807.92(a)(5)]
