Bipolar Linear Pens

Isolator multifunctional Pen

• Semi-rigid shaft provides stable contact with target area
• “Pen-Point” accuracy delivers predictable energy for painting and stamping lesions – where you want them, when you want them
• Can pace, sense stimulate and ablate

AtriCure's Coolrail™ linear pen

AtriCure’s Coolrail linear pen is the latest ablation tool designed to create additional lesion lines on soft tissue. Using resistive heating, full thickness lesions are created by circulating internal cooling fluid in a closed-loop system, keeping surface temperature and tissue impedance low. As a result, energy is driven deeper into the tissue, reducing the potential for gaps associated with stamping lesions.

At t=0 seconds; current flow is initiated between the two electrodes. Current lines are depicted by the red lines.

At t=20 seconds; resistive heating occurs under the electrodes as energy is driven deeper into the tissue. Internal cooling channels maintain current density throughout the ablation cycle.

At t=40 seconds; energy continues along deeper conductive pathways until a full-thickness lesion is achieved.

Physical Features

• 30 mm length electrodes decreases technique and time associated with creating long linear lesions
• Distal segment articulates +/-25 degrees to improve access to anatomical structures
• Malleable 7.5 cm distal shaft allows electrodes to be positioned for full contact in various port placements
