Macro/micro duty cycle devices, systems, and methods employing low-frequency ultrasound or other cyclical pressure energies

摘要

Improved devices, systems, and methods treatment of patients can be used to help mitigate injury to the kidneys by applying cyclical mechanical pressure energy at low intensities. The energy often be selectively directed from non-invasive transducers disposed outside the patients. The energy will typically comprise low frequency ultrasound energy, shock wave energy, or the like, and may induce the generation and/or release of nitric oxide, thereby enhancing perfusion and ameliorating tissue damage. Superimposed micro and macro duty cycles may help avoid thermal and other injury to tissues of the patient during treatment. Bilateral treatments are facilitated by a support structure that orients at least one transducer toward each kidney.
