Microwave 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 comprising an elongated shaft. The elongated shaft is sized and configured to deliver a microwave transmission element to a renal artery via an intravascular path. Renal neuromodulation may be achieved via dielectric heating in the presence of microwave irradiation that modulates neural fibers that contribute to renal function or alters vascular structures that feed or perfuse the neural fibers.本文揭示藉由血管內接達實現腎臟神經調節之微波導管裝置、系統及方法。本申請案之一態樣係針對例如併入有包含伸長軸之導管治療器件的裝置、系統及方法。該伸長軸經定大小且經組態以經由血管內路徑遞送微波傳輸元件至腎動脈。腎臟神經調節可在調節有助於腎臟功能之神經纖維或改變饋送或灌注該等神經纖維之血管結構的微波輻射存在下經由介電加熱實現。
