What is it indicated for?
For use in cardiac electrophysiology procedures to assist in the diagnosis of arrhythmias that may be difficult to identify using conventional mapping systems alone (i.e., linear mapping catheters). The Ablacon Ablacath™ Mapping Catheter may also be used for delivery of externally generated pacing stimuli.
Indications for use as stated in the FDA summary.
