Therapy Cool Path Duo™ Ablation Catheter, Safire BLU Duo™

The FDA granted pre-market approval to St. Jude Medical for the company’s Therapy Cool Path Duo and Safire Blu Duo cardiac ablation catheters and the matching IBI1500T9-CP V1.6 generator to power them.Therapy-Cool-Path-Duo

The catheters provide cooling irrigation all around the tip from a dozen ports so that only targeted tissue is destroyed.  The system is already cleared for marketing in Europe.

Some of the features:

  • Externally irrigated ablation catheter with additional irrigation ports for more uniform cooling
  • Lower average measured tip temperature at equivalent flow rates compared to distal tip irrigation only 
  • Fewer incidences of coagulum and charring observed in preliminary study
  • All-braided construction provides uninterrupted torque transfer for more responsive handling
  • M, L, XL, and L1 curve configurations

This is a brief overview of information related to FDA’s approval to market this product. See the links below to the Summary of Safety and Effectiveness Data (SSED) and product labeling for more complete information on this product, its indications for use, and the basis for FDA’s approval.

Approval Letter:

What is it? The Therapy Cool Path Duo™ Ablation Catheter or the Safire BLU Duo™ Ablation Catheter is a steerable, deflectable, irrigated catheter (a long, thin, flexible tube) used to treat a certain kind of abnormal heart rhythm (arrhythmia) called typical atrial flutter by finding the source of the rhythm disturbance and destroying (ablating) small areas of the heart tissue. The catheters take energy from an external source (the IBI1500T9-CP V1.6 Cardiac Ablation Generator) to a point in the right side of the heart.

How does it work? The Therapy Cool Path Duo™ Ablation Catheter or the Safire BLU Duo™ Ablation Catheter is inserted into a blood vessel (artery or vein), usually though a site in the upper leg or neck. The catheter is manually advanced through the blood vessels until it reaches the correct location inside the heart. The tip of the catheter is moved around by a mechanism on the handle. Inside the heart, electrodes at the tip gather data that pinpoint the location of the faulty tissue in the heart (electrical mapping). Once the site is identified, the device delivers radiofrequency (RF) energy to destroy the small areas of tissue that blocks the heart’s internal electrical signals that cause the typical atrial flutter. The catheters are removed after treatment.

When is it used? The Therapy Cool Path Duo™ Ablation Catheter or the Safire BLU Duo™ Ablation Catheter, and the IBI 1500T9-CP V1.6 Cardiac Ablation Generator are used to destroy small areas in the heart that cause an abnormally fast heart beat or abnormal heart rhythm in the upper chambers (the atria) of the heart. The technical name for this kind of abnormal heart beat is typical atrial flutter.

What will it accomplish? Cardiac catheter ablation can cure typical atrial flutter and restore a normal heart rhythm, and in other cases, can reduce the frequency of episodes that a patient experiences. In a clinical study involving 188 patients, the abnormal rhythm (typical atrial flutter) was corrected in 181 patients (96%) for 7 days after treatment; and it remained corrected after 3 months in 174 patients (94.5%).

When should it not be used? The device should not be used in patients:
