Full circle ablation. No rotation.

Designed for every EP, the Sphere‑360™ PFA system delivers safe, efficient, and durable PVI through a simple ZeroTurn™ workflow1. It achieves complete isolation in only four applications with no catheter rotation needed.

The adjustable lattice seamlessly expands from linear to disc shape up to 34 mm, adapting to a wide range of PV anatomies.1

The catheter provides easy maneuverability with a conformable,3 atraumatic lattice.

360 integration. Zero exchange.

The Sphere‑360™ PFA catheter is exclusively integrated with the Affera™ mapping and ablation system. Its all‑in‑one design delivers navigation, mapping, and ablation through a single catheter.

Consistent outcomes. Full confidence.

The Sphere-360™ catheter delivers predictable workflows and lasting results across centers — with reliability and confidence in your procedure.

The Sphere-360™ CE Mark study was a prospective, single-arm, multicenter trial. It was designed to evaluate the safety, effectiveness, and lesion durability of the Sphere-360™ catheter. The catheter was used for the treatment of symptomatic, drug-refractory paroxysmal atrial fibrillation (PAF) in 100 patients.¹

Sphere-360™ offers a new generation catheter for a single shot ablation. The high conformability of the catheter performs very well. Because it is a compliant sphere, it can adapt to the tissue ... It can be seamlessly adapted to different shapes, because the anatomy of the pulmonary vein is highly individualized.”
