JLL EP Diagnostic Catheters

Go Further. Know More.™

Enhanced diagnostic precision for coronary sinus mapping and beyond.

JLL EP Diagnostic Catheter - Fixed Curve 2F

The JLL 2F microcatheter enables mapping and pacing in distal coronary sinus branches, inaccessible to other catheters. 

JLL EP Diagnostic Catheter - Fixed Curve 6F CS with Lumen

The JLL 6F catheter is an EP catheter capable of mapping in the CS. It is torquable with a large lumen, facilitating placement and telescoping of the 2F microcatheter in the coronary venous system.

2F Confidence

Atraumatic distal tip facilitates confidence in accessing branches of the CS.

2F Enhanced Pacing

Larger 1.5 mm and 1.3 mm electrodes for crisp electrograms and better pacing.

Broad Coverage

With the octapolar JLL 2F and the decapolar JLL 6F Catheter with Lumen, achieve optimal coverage for mapping with 18 electrodes total.

6F Soft Touch

Maneuver confidently in the CS: stiffness decreases gradually towards a soft distal tip.

6F Large Lumen

Wide lumen allows for flushing and aspiration of fluids, and is compatible with devices up to 0.035” diameter.

6F Control

Fully braided shaft, even under electrodes, allows greater maneuverability.

JLL EP Diagnostic Catheter - Fixed Curve 2F

2F microcatheter may be deployed to map in the distal branches of the CS.

2F mapping has been used for:
- Idiopathic VTs1,2
- Complex ATs3,4
- Left WPW 5
- Mapping and pacing in VOM3,6
