Abbott Livewire 401991 Steerable Catheter – Extra Large Curl, Deflectable Tip, Sterile

Abbott (St. Jude Medical) Livewire Decapolar EP Catheter | 5F | XL Curl | 401991

The Abbott 401991 is an elite diagnostic tool designed for high-density intracardiac mapping. Combining a slender 5 French (5F) profile with a Decapolar (10-electrode) array, this catheter is engineered for the most demanding electrophysiology (EP) studies. The Extra Large (XL) Curl configuration provides the expansive reach and stable contact required to map larger cardiac architectures—such as the lateral wall of the right atrium or the ventricular outflow tracts—where standard curls may lose apposition.

Equipped with a 2-5-2 mm electrode spacing, the 401991 facilitates high-resolution electrogram recordings, allowing for the precise localization of complex arrhythmias and the identification of fragmented potentials.

Technical & Clinical Advantages

• Decapolar Signal Fidelity: The 10-electrode configuration provides five bipoles for simultaneous recording across a broader segment of endocardium. This is essential for observing activation sequences in the coronary sinus or the crista terminalis.

• Lower-Profile 5F Shaft: The 5F diameter reduces the puncture site footprint and allows for easier passage through smaller or more tortuous venous anatomy compared to standard 6F or 7F catheters.

• XL Curl Stability: The Extra Large curve is specifically designed to maintain contact in dilated chambers. Its "bridge-like" stability ensures that the electrodes remain stationary during the cardiac cycle, preventing signal artifacts caused by catheter "chatter."

• Rotary Dial Precision: The signature Livewire™ handle provides 1:1 mechanical response. The rotary dial allows the surgeon to "lock in" the desired curvature, ensuring the tip does not drift during mapping.

• Fluoroscopic Clarity: High-density platinum electrodes and a radiopaque shaft provide a crisp silhouette under X-ray, allowing for confident placement without the need for excessive fluoroscopy time.

Applications

• High-Density Mapping: Recording multiple signals simultaneously to identify macro-reentrant circuits.

• Coronary Sinus Mapping: Providing 10 poles of visualization for left-sided pathway evaluation.

• Diagnostic EPS: Standardized evaluation of the SA and AV node conduction.

• Complex Arrhythmia Localization: Precise identification of accessory pathways and ectopic foci in the atria or ventricles.
