Medtronic Sphere-9 Catheter, Model Number AFR-00001; catheter, percutaneous, cardiac ablation, for treatment of atrial flutter.

Class II
Recalling firm
Medtronic, Inc.
Reason for recall
ventricular fibrillation (VF) during radiofrequency (RF) therapy with the Medtronic Sphere-9 catheter in patients who have a Biotronik Implantable Cardioverter Defibrillator (ICD) or Biotronik Cardiac Resynchronization Therapy-Defibrillator (CRT-D) implanted. The observation is caused by an interaction between the Sphere-9 catheter current flow and a safety feature built into Biotronik ICDs and CRT Ds. Medtronic recommends physicians use increased caution when using the Sphere-9 catheter for RF ablation therapy in patients implanted with a Biotronik ICD/CRT-D system, and to ensure external defibrillation systems are readily available.
