The summary describes a diagnostic recording system using ultrasound, ECG, EGM, and impedance-based localization for cardiac mapping. It focuses on data acquisition, reconstruction, and display of electrical activity and catheter position. There is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies.
No.
The device is described as a "diagnostic recording system" intended for imaging, navigation, and mapping to help physicians identify the source of arrhythmia, not to provide therapy itself.
Yes
The "Intended Use / Indications for Use" section and "Device Description" section explicitly state that the AcQMap System is a "diagnostic recording system" and is used to "visualiz[e] the chamber anatomy and displac[y] electrical impulses as either dipole density-based or voltage-based maps of complex arrhythmias that may be difficult to identify using conventional mapping systems alone." It also mentions that "The surface reconstruction and electrical map are then used by physicians to identify the source(s) of the arrhythmia." These functions are diagnostic in nature.
No
The device description explicitly states that the system consists of hardware components including a console, workstation, patient interface unit, and ablation interface unit, and relies on ultrasound imaging, ECG/EGM recording, and impedance-based localization.
Based on the provided information, the AcQMap® High Resolution Imaging and Mapping System is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- AcQMap System Function: The AcQMap System operates in vivo (within the living body) during electrophysiology procedures. It uses ultrasound and electrical signals to image, navigate, and map the heart chambers. It does not analyze samples taken from the patient.
- Intended Use: The intended use clearly states it's for use in patients for electrophysiology procedures, visualizing chamber anatomy, and displaying electrical impulses within the heart.
- Device Description: The description confirms it's a diagnostic recording system used in the Electrophysiology (EP) Lab and operates outside of the sterile field but interacts with components (catheters and electrodes) that are within or on the patient.
Therefore, the AcQMap System is an in vivo diagnostic device, not an in vitro diagnostic device.

The AcQMap® High Resolution Imaging and Mapping System ("AcQMap 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 the atrial chambers of the heart.
The AcQMap System hardware consists of three functional subsystems:
- Ultrasound imaging.
- ECG and EGM recording; and
- Impedance based electrode Localization.
The AcQMap System is used in conjunction with the associated AcQMap 3D Imaging and Mapping Catheter. The AcOMap System provides:
- 3-D cardiac chamber reconstruction imaging,
- Three-dimensional position of the AcQMap Catheter and conventional electrophysiology catheters,
- Cardiac electrical activity as waveform traces,
- Remapping of the chamber at any time during the procedure; and
- Three-dimensional, dipole density-based maps overlaid on the cardiac chamber reconstruction to show chamber-wide electrical activation.
The AcQMap System is a diagnostic recording system consisting of ultrasound, electrical mapping components, a console, and a workstation. The AcQMap 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 arrhythmia.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE [807.92(A)(6)]
This submission is seeking the clearance of the updated AcQMap System, which has the included software features, Anatomic Reference, Markers Enhancement, and Graphical User Interface Refresh.
Anatomic Reference allows the Anatomic Reference Channels to be used to subtract respiratory motion from all devices navigated by the system. With Marker Enhancement, markers can now be optionally "snapped" to the anatomy when the user-selected electrode is within 4mm of the reconstructed surface. Graphical User Interface Refresh is a functionality that was previously accessed through dropdown menus but can now be additionally accessed through readily available icons within the user interface.
Table 1 provides a comparison of the modified AcQMap System classification and indications for use against the predicate and reference devices. Table 2 provides a comparison of the technological characteristics for the modified AcQMap System against the predicate device.

SUBSTANTIAL EQUIVALENCE
The indications for use for the AcOMap High Resolution Imaging and Mapping System predicate device are identical to the proposed indications for use for the AcQMap High Resolution Imaging and Mapping System in this submission. Any differences in the technological characteristics between the devices do not raise any different questions of safety or effectiveness. Thus, the AcQMap System is substantially equivalent to the predicate device.
PERFORMANCE DATA [807.92(b)]
All necessary bench and clinical testing was conducted on the AcQMap System to support a determination of substantial equivalence to the predicate device.
[807.92(b)(1)] Nonclinical Testing Summary

The collective results of the testing demonstrate that the design of the AcQMap System meets its established performance specifications necessary for performance during its intended use.
The collective results of the nonclinical testing demonstrate that the materials chosen, the manufacturing processes, and design of the AcQMap System meet the established specifications necessary for consistent performance during its intended use. In addition, the collective bench testing demonstrates that the AcQMap System does not raise different questions of safety or effectiveness.
[807.92(b)(2)] Clinical Testing Summary
Although clinical testing is not required to demonstrate substantial equivalence to the predicate device for its intended use. Acutus performed a clinical study to demonstrate the safety and performance of the AcQMap High Resolution Imaging and Mapping System in gathering data to create right and/or left atrial dipole density activation maps in subjects with supraventricular tachycardia. The study entitled, "Dipole Density Right (and left) Atrial Mapping and Assessment of Therapy In Complex Supraventricular Tachycardia, (DDRAMATIC-SVT)" is a prospective, non-randomized, open-label study conducted at eight clinical sites outside the U.S. The results for 84 patients demonstrate that the AcQMap System is safe and effective for its intended use.

CONCLUSIONS [807.92(b)(3)]
Extensive nonclinical performance testing was conducted on the AcQMap System to evaluate the overall performance of the device. The collective results demonstrate that the AcQMap System is safe and effective for its intended use.
SUMMARY
The AcQMap System is substantially equivalent to the predicate device, the previously cleared AcQMap System.
