DESCRIPTION OF MODIFICATIONS:
MULTIPOLAR MAPPING 1.1
The Multipolar Mapping provides an additional annotation to the Wavefront Annotation mechanism, designed to enable a better discrimination between local activation and far-field potentials, and results in an improved consistency of the LAT annotation and Voltage measurements.
AUTO PATTERN ACQUISITION 1.2
Auto Pattern Acquisition automatically acquires BS ECG or IC EGMs patterns for either ventricular or atrial mappings. Automatic acquisition is achieved through a clustering mechanism using incoming beats, grouped based on similar morphology, to create different maps for the patterns of interest.
6
COMPLEX SIGNALS IDENTIFICATION 1.3
The Complex Signals Identification (CSI) module is a machine learning locked algorithm that automatically tags fractionated IC ECG signals. This module allows the identification and visualization of complex signals during continuous mapping mode or retrospectively. In addition, tools for viewing the identified complex signals in specific regions of interest are provided.
For developing and validating the algorithm, a control database was created using input from multiple stable atrial typical and atypical flutter cases. This data was sourced from Medical Centers in Europe and the United States of America. It included data from different catheters, with complex signals, single activations, noisy signals, and so on.
CARTOSOUND™ FAM 1.4
The CARTOSOUND™ FAM Module is used to automatically reconstruct an editable 3D volume with automatic 3D segmentation of the Left Atrium (LA) anatomies, based on a series of 2D ultrasound gated input frames acquired from the Right Atrium (RA, Fossa Ovalis) and/or the Right Ventricular Outflow Tract (RVOT).
The CARTOSOUND™ FAM Module incorporates a Deep Learning (DL) algorithm. Data for training and validation of the DL algorithm was collected from diverse locations and populations, using a variety of ultrasound system settings, scanners, and Catheters.
1.5 LAT VELOCITY VECTORS (LVV)
The LAT Velocity Vectors (LVV) enables a visual display of the conduction mechanism in the chamber via velocity vectors on top of the 3D map, indicating the speed and direction of the activation wave as it propagates through the chamber.
1.6 CATHETERS SUPPORT
CARTO™ 3 system improved support of QDOT Micro™ Catheter:
CARTO™ 3 system V8.0 includes the following QDOT Module Improvements on the CARTO software version that was part of PMA P210027: enhanced ECG channels filters, addition of nGEN PUMP
7
real-time flow rate display, display improvement, reflection of irrigation changes for focal ablation and during ablation only.
CARTO™ 3 system support of OPTRELL™ Mapping Catheter through SPU:
Visualization and mapping capabilities for the OPTRELL TM Mapping catheter. OPTRELL support includes Local Conduction Vectors (LCV), showing visualization of the wave propagation through the OPTRELL™ Catheter, indicating direction and speed.
CARTO™ 3 system support of LASSOSTAR NAV:
Visualization and mapping capabilities for LASSOSTAR NAV Circular Mapping Catheter.
1.7 LEGACY FEATURES MODIFICATIONS
VISITAG Module - Compensated VISITAG Stability Algorithm:
The VISITAG stability indication in the predicate device CARTO® 3 System V7.4 is based on the ACCURESP™ algorithm that provides the ablation catheter end-expirium locations, meaning that stability indication is updated once every respiration cycle. A modified respiration decomposition ("Compensated") algorithm was developed that estimates the catheter motion in real-time based on the respiration originated motion and subtracting it from the measured location. The Compensated Stability algorithm enables faster feedback to user at the beginning of ablation ensuring VISITAG early appearance, when the stability conditions are maintained.
Late Annotation Mapping (LAM):
Late Annotation Mapping provides an additional mapping criterion that allows a Late Boundary (LB) annotation line to be placed within the standard LAT Window of Interest (WOI).
CONFIDENSE Module - SmartMap:
In the legacy CONFIDENSE™ Module design, the map is colored according to the first point that passed the CONFIDENSE™ filter thresholds and was acquired in every specific location, and such that new potential points will be filtered out if the position is already occupied, even if they also passed the CONFIDENSETM filter thresholds (first comes, first stays).
With SmartMap, each potential point in the study is rated with a Smart Index, indicating its relative quality based on quality parameters
8
(Pattern matching, Respiration, LAT stability, Position stability, Tissue proximity, Signal sharpness). SmartMap prioritizes high Smart Index score points over low Smart Index score points when building maps, by swapping points in the map according to their Smart Index score (best comes, best stays even if not first).
