Why choose CEDAR RFA System

Intuitive

CEDAR provides a seamless RFA procedure experience. Designed for intuitive set up, the generator’s touch screen displays real-time parameters and key procedure information, and provides auditory feedback during treatment.

Available with 3 cm or 7 cm heating coil treatment lengths, the catheter features clear markings and one-button activation.

Reliable

Designed for efficient procedures. The CEDAR catheter’s coil consistently heats to 120° C for effective destruction of the endothelial cells to induce venous spasm and closure of the targeted segment. You can count on consistent product supply and robust support services from a trusted partner.

Effective

CEDAR RFA System is backed by Level 1 clinical evidence, which demonstrated 97.78% closure of the GVS, 0 safety incidents, and -3.7+3.97 VCSS Score change.¹

Clinical data

CEDAR RFA clinical trial outcomes

A multicenter, randomized controlled trial evaluating a new radiofrequency ablation system in the treatment of primary great saphenous vein incompetence: Six-month results of the ACOART RF CLOSURE study¹

Study Overview

Multicenter, randomized controlled trial evaluating the CEDAR RFA system versus ClosureFast™
188 patients with primary great saphenous vein (GSV) incompetence enrolled across 5 vascular centers
Primary endpoint: total GSV occlusion at 6 months
Secondary endpoints: device success, technical success, patient‑reported outcomes (AVVQ, VCSS), and safety

Key Results

Effectiveness

Complete GSV occlusion at 6 months:
- CEDAR: 97.78%
- ClosureFast: 98.86%
Device success: 100% for both systems
Immediate technical success: 100% for both systems
Patient outcomes: Significant and comparable improvement in AVVQ and VCSS scores in both groups
Large‑diameter vein performance:
- Patients with GSV ≥12 mm: 100% occlusion at 6 months for both devices

Safety

Overall adverse event rates comparable between systems
No device‑related adverse events or serious adverse events (SAEs) recorded
