Distinct design

We're committed to evidence and innovation.

Our new ClosureFast 6F catheter builds on the RFA technology that's been trusted since 2006.

Technology and data overview

Joe Zygmunt, Medtronic portfolio advisor, talks about the history, clinical experience, and long-term performance of the ClosureFast procedure.

Why catheter design matters

Lead engineer Chuanjing Xu explains how the design of the new ClosureFast 6F catheter impacts performance — and what makes it unique.

The value of compression detection

Engineer John Elhard describes the feedback loop between the ClosureFast catheter and generator and how it provides real-time information to the physician.

Patented overlap design

Engineer Sarah Thole talks about the value of the ClosureFast system’s patented gap-free technology for thermal ablation.

Physician experience

Three highly experienced ClosureFast RFA users share their experience with flexibility and navigation using the new ClosureFast 6F catheter.
