Programmable Microwave Ablation System Gains CE Mark for Minimally Invasive Tissue Ablation

Thermal ablation systems are used across multiple clinical specialties, where predictable ablation geometry and programmable power-time profiles can support procedural consistency. A new system now combines a spherical ablation zone with programmable, multi-step energy delivery within a single ablation cycle.

RF Medical’s (Seoul, South Korea) Mi-BLATOR microwave ablation system comprises a generator and antennas designed for image‑guided, minimally invasive procedures. The platform adds microwave technology to the company’s established radiofrequency ablation (RFA) portfolio, broadening the range of thermal ablation modalities available within its product line. Together, the components are intended to support procedural planning while maintaining consistent ablation performance across cases.

The Mi-BLATOR antenna uses a proprietary feedline design to create a spherical ablation zone, enabling uniform energy deposition within the targeted region. The generator provides a multi‑step mode that allows clinicians to pre‑set power and duration for each step within a single ablation cycle. These features are designed to support treatment planning and help optimize energy delivery throughout the procedure.

RF Medical announced that Mi-BLATOR has obtained CE marking under the European Union’s Medical Device Regulation (MDR), with certification covering both the generator and antennas. The authorization enables introduction of the system to the European market and offers healthcare professionals an additional thermal ablation option to address clinical needs. 

The company noted that the addition of microwave technology complements its RFA portfolio and supports plans to expand access across Europe. The milestone follows CE marking under the EU MDR for THYBLATE‑V2 in September 2026; the adjustable‑tip thyroid RFA electrode, already available in multiple international markets, added European certification to its regulatory authorization in Korea and U.S. Food and Drug Administration (FDA) 510(k) clearance.
