catheter apparatus for thermally modulating renal nerves from within a renal artery; and catheter apparatus for intravascular renal neuromodulation

摘要

catheter apparatus for thermally modulating renal nerves from within a renal artery; and catheter apparatus for intravascular renal neuromodulation. catheter apparatus, systems and methods for obtaining intravascular access renal neuromodulation are described herein. One aspect of the present invention, for example, is directed to apparatus, systems and methods incorporating a catheter treatment device comprising an elongate stem. The elongated stem is sized and configured to provide a power supply element for a renal artery via an intravascular pathway. Thermal or electrical renal neuromodulation may be obtained by direct and / or indirect application of thermal and / or electrical energy to heat or cool or otherwise electrically modulate neural fibers that contribute to renal function, or vascular structures that supply or promote perfusion of neural fibers.
