High-Intensity Ultrasonic Vessel Ablator Using Blood Flow Signal for Precise Positioning

A ultrasonic diagnostic and therapeutic system, which utilizes high-intensity focused ultrasound for ablating blood vessels and blocking blood flow, comprising:

• (1) an ultrasound transducer module, for diagnosis and therapy, comprising a focused ultrasound transducer and a plastic device;
• (2) a diplexer module coupled to the ultrasound transducer module, for transmitting diagnostic ultrasound, receiving echo signals (Doppler signals) from blood flow in response to the transmitted ultrasound and delivering therapeutic ultrasound;
• (3) a diagnostic processor coupled to the diplexer module, for producing diagnostic control signals and responsive to the echo signals for identifying a location of blood flow in real time;
• and
• (4) a therapeutic processor coupled to the diplexer module, for producing therapeutic control signals.
