The VIKING Fixed Curve Diagnostic Catheter is indicated for use to diagnose cardiac arrhythmias.

The Viking Fixed Curve Diagnostic Catheters (also referred to as Viking Catheters) are intended for use in electrophysiology procedures to record, stimulate and pace in the diagnosis of cardiac arrhythmias. The Viking Catheters receive electrical signals from the cardiac tissue, which are transmitted via the electrode wiring through the connector and cable to an amplifier, where the signals are displayed on an EP recording system for the physician to view and interpret in diagnosing cardiac arrhythmias. The physician inserts the diagnostic catheter into the vasculature percutaneously. To reach the right side of the heart, either the internal jugular vein, the subclavian veins, or the femoral veins can be accessed. To reach the left ventricle, the retrograde approach via the femoral artery can be used. In some cases, the radial artery may be used to access the targeted cardiac chamber. Using fluoroscopic guidance, the physician then navigates the diagnostic catheter to the target site using the catheter steering mechanism, as confirmed by the intracardiac electrograms and/or pacing threshold, confirming electrode to endocardium interface. Viking Catheters are radiopaque, flexible, insulated catheters. The catheters have a polymer shaft that houses the electrical wiring that connects the electrodes to a connector at the proximal end of the catheter; each electrode wire is soldered into this connector. When the catheter is used, the connector is attached to a sterile cable that connects to the hospital recording and pacing equipment. The Viking Catheters are offered pre-packaged sterile and are a single use product not to be reused, reprocessed, or resterilized. The method of sterilization is ethylene oxide (EO).

EP.XT, Dynamic Tip, and Dynamic XT Unidirectional Steerable Diagnostic Catheters are indicated for use to diagnose cardiac arrhythmia.

The unidirectional steerable diagnostic catheters acquire electrical signals from the cardiac tissue, which are transmitted via the electrode wiring through the connector and cable to an amplifier, where the signals are displayed on an EP recording system for the physician to view and interpret in diagnosing cardiac arrhythmias. The physician inserts the diagnostic catheter(s) percutaneously via either the anterior approach using the internal jugular vein or the subclavian vein or via the femoral vein or for a retrograde approach, via the femoral artery. In some cases, the radial artery may be used to access the targeted cardiac chamber. Using fluoroscopic guidance, the physician then navigates the diagnostic catheter to the target site using the catheter steering mechanism as confirmed by the intracardiac electrograms and/or pacing threshold, confirming electrode to endocardium interface. The steerable diagnostic electrode catheters are radiopaque, flexible, insulated catheters with a polymer shaft, each having a mechanical operating mechanism. In each catheter the polymer shaft connects to the catheter handle whereby the curve or loop is actuated by a single pull cable. The EP+XT Catheter has a white rotating handle mechanism which provides curve actuation of the distal tip. The Dynamic Tip and Dynamic XT Catheters have a plunger mechanism, which, when moved forward or back, results in curvature of the distal tip. The EP•XT, Dynamic Tip, and Dynamic XT Catheters are offered pre-packaged sterile and are a single use product not to be reused, reprocessed, or resterilized. The method of sterilization is ethylene oxide (EO).
