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.
A story of resilience
After losing a leg to phlebolymphedema, Iona’s doctor performed the ClosureFast procedure to help save her remaining leg and restore mobility — and hope.
“I may have lost a leg, but I gained a life.” – Iona
Results may vary. Talk to your doctor for more information.
