What is it indicated for?

The Mercator Atrial High Density Array Catheter 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). When used in conjunction with electrogram recording equipment and stimulators, the system is used to record intracardiac electrogram (EGM) signals and to deliver pacing pulses for the purpose of diagnostic provocative…

The Mercator Atrial High Density Array Catheter 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). When used in conjunction with electrogram recording equipment and stimulators, the system is used to record intracardiac electrogram (EGM) signals and to deliver pacing pulses for the purpose of diagnostic provocative stimulation during an electrophysiology procedure.

The Mercator Atrial High Density Array Catheter can be used with:

o the Cardiac Pathways’ Model 8100 Arrhythmia Mapping System and the Model 8300 Signal Acquisition Module in conjunction with a stimulator, and

o Cardiac Pathways’ EGM Adapter Cables (Models 2036, 2043, and 2044) in conjunction with intracardiac electrogram recording equipment.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
