Ultrasound systems and methods for treating ischemic limbs or tissue affected by peripheral arterial disease

摘要

A method of treating tissue within a body includes aiming an ultrasound transducer towards target tissue, and delivering ultrasound energy towards the target tissue to thereby reduce pain at the target tissue. A method of treating tissue within a body includes aiming an ultrasound transducer towards target tissue, and delivering ultrasound energy towards the target tissue to increase nitric oxide at the target tissue. An ultrasound system includes a first ultrasound transducer for emitting ultrasound energy from outside a patient, and drive circuitry coupled to the first ultrasound transducer, wherein the drive circuitry is configured to generate a drive signal at a frequency that is between 20 kHz and 100 kHz for the first ultrasound transducer.
