2022 AF Symposium: Spherical Array Catheter Case with Video

Published March 29, 2022

Note: This was a very early, first-in-human use of this Spherical Array PFA catheter not yet approved by the FDA.

Dr. Vivek Reddy from Mount Sinai Medical Center in New York City, NY, showed a fascinating video of how the spherical PFA catheter emerged from the catheter sheath and formed itself into a spherical array, then locked itself into shape.

It was like watching a magic trick. How could they design a catheter sheath from which would emerge a complex spherical shaped catheter that would come together so smoothly?

On the video, we watched as Dr. Reddy and his team performed a Pulsed Field Ablation using the Spherical Array Catheter. The patient was a 31-year-old male diagnosed with paroxysmal A-Fib in 2020.

How the Spherical Array Catheter Works

Once fully deployed, the spherical PFA catheter has a diameter of 30 mm. It contains 122 gold-plated electrodes on 16 splines around the sphere. Continue reading about the Spherical Array catheter and the Pulsed Field Ablation for this patient.
