AtriCure's Coolrail™ linear pen

Advanced science applied to the formation of cardiac linear ablations

Launch in external player

AtriCure’s Coolrail linear pen is the latest ablation tool designed to create additional lesion lines on full-volume cardiac 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

 

The Coolrail™ linear pen is intended for the ablation of cardiac tissue during surgery.  For additional information, see the summary of the FDA's 510(k) clearance.
