20150327924 | SYSTEMS, DEVICES, AND METHODS FOR MODULATING RENAL NERVE TISSUE - Methods for treating a patient using therapeutic renal neuromodulation and associated devices, system, and methods are disclosed herein. One aspect of the present technology is directed to neuromodulating nerve tissue in selected anatomical regions. In one embodiment, the method can include intravascularly advancing an elongate shaft of a catheter to renal vasculature of a human patient and locating a first neuromodulation element of the catheter within a distalmost portion of a main renal artery. The method includes locating a second neuromodulation element of the catheter within a branch vessel of the renal artery distal to a bifurcation at a distal end of the main renal artery. Neuromodulation of the nerve tissue surrounding the selected anatomical treatment locations can inhibit sympathetic neural activity in nerves proximate a portion of a renal artery and/or a renal branch artery proximate a renal parenchyma. | 2015-11-19 |
20150327925 | IRRIGANT DISTRIBUTION SYSTEM FOR ELECTRODES - An ablation electrode assembly is provided with improved irrigation cooling of the assembly and ablation site. The assembly includes a proximal end configured to be coupled to a catheter shaft and a distal end configured to deliver ablation energy to tissue. The assembly further includes a fluid manifold extending from the proximal end to the distal end and configured to fluidly communicate with a fluid lumen in the catheter shaft. The fluid manifold defines an axial passageway centered about a longitudinal axis extending in the longitudinal direction of the assembly. The axial passageway has a distal end terminating prior to the distal end of the electrode assembly. The assembly further includes means for creating turbulence in fluid exiting the first axial passageway. | 2015-11-19 |
