A sterile, steerable, flexible tube containing multiple electrodes that is introduced percutaneously into the heart chambers in order to transmit electrical impulses for electrophysiological diagnostic examinations, e.g., intracardiac sensing, endocardial recording, stimulation, temporary pacing for evaluation of cardiac arrhythmias and cardioversion (CV), and electrophysiology (EP) mapping. It is typically made of plastic with embedded electrodes often of platinum (Pt), iridium, or a composite. This is a single-use device that has previously been used on a patient and has been subjected to additional processing and manufacturing for an additional single-use patient application.
