The Focal One device is an advanced, robotic-assisted High-Intensity Focused Ultrasound (HIFU) medical platform specifically utilized to treat localized prostate cancer non-invasively. The technology combines high-resolution diagnostic ultrasound or magnetic resonance imaging fusion with high-intensity focused sound waves to precisely target and ablate cancerous tissue within the prostate gland while leaving surrounding healthy structures—such as nerves responsible for erectile function and urinary sphincters—completely unharmed. This robotic focal approach allows urologists to destroy diseased tissue accurately with millimetric precision, minimizing side effects and preserving patient quality of life.
