Abstract

The disclosure pertains to an intravascular catheter for nerve modulation, comprising an elongate member having a proximal end and a distal end, a balloon having a lumen and a balloon wall, the balloon wall comprising RF permeable sections and non-electrically conductive sections, an electrode disposed within the balloon and extending distally to the furthest distal RF permeable section. The RF permeable sections may comprise a plurality of RF permeable windows, each window having a greater circumferential dimension than an axial dimension. The intravascular system is suited for modulation of renal nerves.

Description

[0001] Cross References to Related Applications [0002] This application claims under 35 U.S.C § 119 U.S. Provisional Application No. 61 / 580,972 filed December 28, 2011, U.S. Provisional Application No. 61 / 605,615 filed October 1, 2012, and October 3, 2012 Priority to U.S. Provisional Application No. 61 / 605,624 filed on January 1, which are incorporated herein by reference. technical field [0003] The present invention generally relates to percutaneous and intravascular devices for performing nerve modulation and / or ablation. Background technique [0004] Certain treatments require the temporary or permanent interruption or modification of selected neural functions. An example treatment is renal nerve ablation, which is sometimes used to treat conditions associated with congestive heart failure. The kidneys produce a sympathetic response to congestive cardiac failure which, among other effects, increases undesirable retention of water and / or sodium. Ablation of some of ...
