Enhanced diagnostic precision for coronary sinus mapping and beyond

2F microcatheter telescoping out of 6F catheter with lumen into deeper coronary venous anatomy.

How it works

Multielectrode shafts of EPstar Fixed Electrophysiology Catheters.

EPstar 2F Fixed Electrophysiology Catheter*

The 2F diagnostic microcatheter enables mapping and pacing in distal coronary sinus (CS) branches, which may be inaccessible to other catheters.

EPstar 6F Fixed Electrophysiology Catheter with Lumen

The 6F diagnostic catheter is torquable with a large lumen, facilitating placement and telescoping of the 2F microcatheter in the coronary venous system.

Using the EPstar 2F Microcatheter*

Enable mapping and pacing in distal coronary venous system branches with the octapolar* 2F microcatheter for deeper diagnostic precision

2F mapping has been used for:

  • Idiopathic ventricular tachycardias1,2
  • Complex atrial tachycardias3,4
  • Left Wolff-Parkinson-White5
  • Mapping and pacing in vein of Marshall3,6

Why choose EPstar Fixed Electrophysiology Catheters

Complex diagnostic mapping solutions

Detail of the braided shaft and multiple electrodes along the EPstar 6F Fixed Electrophysiology Catheter.

Broad coverage

Achieve optimal coverage for diagnostic mapping with 18 electrodes total using the octapolar 2F microcatheter and the decapolar 6F catheter with lumen

Atraumatic distal electrode tip of the EPstar 2F Electrophysiology Catheter.

Confidence to access CS

Atraumatic distal tip of the 2F microcatheter facilitates confidence in accessing branches of the CS

Tip electrode with lines indicating pacing.

Enhanced pacing

Larger 1.5 mm and 1.3 mm electrodes of the 2F microcatheter enable crisp electrograms and better pacing

Flexible and atraumatic soft distal tip of the EPstar 6F Fixed Electrophysiology Catheter with Lumen.

Soft touch 

Maneuver confidently in the CS using the 6F diagnostic catheter; stiffness decreases gradually towards a soft, atraumatic distal tip

Wide lumen

3F lumen is compatible with devices up to 0.035” diameter and allows for flushing and aspiration of fluids

Fully braided shaft to allow greater maneuverability.

Catheter control

The 6F catheter’s fully braided shaft, even under electrodes, allows greater maneuverability
