catheter apparatus, renal neuromodulation system, and method for performing renal neuromodulation

摘要

1/1 summary “Catheter apparatus, renal neuromodulation system, and method for performing renal neuromodulation” are described herein catheter devices, systems, and methods for obtaining neuromodulation. Renal injury by intravascular access. One aspect of the present technology, for example, is for a treatment device with a multi-electrode array configured to be delivered to a renal blood vessel. the matrix is selectively transformable between a distribution state, or low profile (e.g. a generally straight shape), and an unfolded state (eg a generally spiral / helical, radially expanded shape) . The multielectrode array is sized and shaped so that the electrodes or energy distribution elements come into contact with an inner wall of the renal blood vessel when the array is in the unfolded state (eg, spiral / helical). the electrodes or power distribution elements are configured for direct and / or indirect application of thermal and / or electrical energy to heat or otherwise electrically modulate neural fibers that contribute for renal function.
