Portable Low Output Impedance Ultrasound System for Therapeutics Uses & Drug Delivery

Technology description

The invention describes a portable and rechargeable high power ultrasound system with a very low output impedance amplifier circuit.

Current ultrasound driving systems are expensive, bulky, and have low energy transfer rates. The present invention relates to a portable, high-power ultrasound system that contains a low output impedance circuit that can transfer more than 95% of the energy it generates to the ultrasound device. Due to its high efficiency, the unit can be run by a rechargeable battery pack and is thus adaptable to a handheld unit with the potential to replace unwieldy and more expensive medical systems as well as RF amplifiers used in research.

Application area

Therapeutic ultrasound may be adapted as a tool to relieve arthritis, enhance wound healing, and improve rehabilitation
Drug delivery uses
Gene transfer applications.

Advantages

Portable ultrasound device suitable for ambulatory, military field use
Increased acoustical driving efficiency
Operating in the range from 1 to 10 MHz (relevant range for medical therapeutic ultrasound and HIFU systems).
