摘要：
Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device that employs high intensity focused ultrasound. The high intensity focused ultrasound may be used for application of energy to modulate neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers. The ultrasound transducer for delivering the energy may be located remotely from the desired treatment area. In particular embodiments, an ultrasound transducer may apply energy at one or more focal zones or focal points that target renal nerves.
