Medtronic Affera Sphere-9 Catheter Receives FDA Breakthrough Device Designation for Ventricular Tachycardia Treatment

Key Takeaways

• FDA grants breakthrough device designation for Medtronic’s Sphere-9 catheter to treat ventricular tachycardia (VT)
• Six-month interim results demonstrate positive outcomes for VT patients treated with Sphere-9 catheter technology
• Sphere-360 catheter receives CE Mark approval in Europe with data showing consistent durability across patient anatomies

Medtronic plc announced significant clinical milestones for its Affera™ cardiac ablation platform at the Heart Rhythm Society (HRS) conference, highlighting breakthrough regulatory progress and positive clinical outcomes for both Sphere-9™ and Sphere-360™ catheters.

FDA Breakthrough Designation Accelerates VT Treatment Access

The FDA granted breakthrough device designation for Medtronic’s Sphere-9 catheter specifically for treating sustained monomorphic ventricular tachycardia (VT), a life-threatening heart rhythm disorder. This designation expedites the regulatory review process for devices addressing unmet medical needs.

Interim results from the pivotal trial, presented as late-breaking data at HRS, revealed promising six-month outcomes for VT patients treated with the Sphere-9 catheter. The FDA has approved the U.S. pivotal trial to proceed, bringing patients closer to accessing this advanced ablation technology.
