ThermoBLOCK Varicose Vein Radiofrequency Ablation System
A radiofrequency ablation platform for incompetent superficial veins, offering thermal closure of saphenous or perforating veins to relieve varicose symptoms.
The Thermal Coagulation RF Ablation Generator is an advanced, feedback-driven system designed to deliver high-frequency radiofrequency (RF) energy to ThermoBLOCK™ catheters and ThermoBLOCK™ stylets—enabling targeted thermal ablation for chronic venous insufficiency (CVI). Equipped with a real-time monitoring mechanism, the generator precisely regulates intravascular heat parameters, ensuring safe and consistent power application while protecting surrounding tissues.
Real-Time Feedback Control
- Heat Parameter Monitoring: Intravascular temperature readings and impedance data are continuously analyzed.
- Automatic Power Regulation: The system modulates RF output based on real-time feedback, maintaining stable thermal therapy without over- or under-heating the vein walls.
Precision RF Delivery
- Targeted Vessel Closure: Concentrates thermal energy along the catheter’s active tip(s), leading to collapsing and sealing of incompetent veins.
- Minimal Collateral Damage: By adapting energy output to real-time conditions, the generator reduces risk of inadvertent injury to neighboring structures.
User-Friendly Interface
- Digital Touchscreen or Control Panel: Operators can easily set and adjust parameters (power, pulse duration, temperature limits) as needed.
- Visual & Audible Cues: Real-time displays of energy output, therapy time, and any alerts keep clinicians informed.
Versatile Integration
- ThermoBLOCK™ Catheter & Stylet Compatibility: Specifically engineered to function seamlessly with ThermoBLOCK™ components, streamlining venous ablation procedures.
- Multi-Mode Operation: Adjustable settings accommodate various vein diameters and lesion characteristics, benefiting physicians performing different CVI treatments.
