StarBurst XL & Semi- Flex RFA Devices


StarBurst XL RFA Device Its real-time, multi-point temperature feedback system ensures sustained target temperatures during the procedure. The patented temperature based end point provides predictable volumes of ablation with low local recurrence rates. Needle track ablation, adjustable array size, and temperature based technology of the revolutionary, first-generation StarBurst XL RFA electrode assures a high level of confidence that coagulative necrosis is taking place throughout the targeted radiofrequency interstitial tissue ablation..

StarBurst Semi-Flex RFA Device The StarBurst Semi-Flex RFA electrode is a versatile device that features both rigid (metal) and flexible (polymer) trocar sections. Its ability to bend up to 90 degrees in all directions enables easy gantry entrance for MRI and CT systems. This teaming of innovative needle design with imaging systems compatibility allows the StarBurst Semi-Flex RFA electrode to be used in percutaneous image-guided procedures. With multiple spherical ablation size capabilities of up to 5 cm in diameter at 1 cm increments, the Semi-Flex covers a broad spectrum of applications.
