  • Patent number: 9757177
    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.

  • Patent number: 9370329
    Abstract: A system for performing mapping and ablation functions includes a catheter sized and shaped for vascular access. The catheter includes an elongate body extending between a proximal end and a distal end. A tip section positioned at the distal end of the catheter body and includes a proximal portion and a distal portion. One or more electrode structures are formed on an exterior surface of the tip section. The one or more electrode structures each includes a mapping electrode at the distal portion of the tip section and a contact pad electrically coupled to the mapping electrode.
