Patent number: 9486270Abstract: Methods and apparatus are provided for bilateral renal neuromodulation, e.g., via a pulsed electric field, via a stimulation electric field, via localized drug delivery, via high frequency ultrasound, via thermal techniques, etc. Such neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, neuromodulation is applied to neural fibers that contribute to renal function. In some embodiments, such neuromodulation is performed in a bilateral fashion. Bilateral renal neuromodulation may provide enhanced therapeutic effect in some patients as compared to renal neuromodulation performed unilaterally, i.e., as compared to renal neuromodulation performed on neural tissue innervating a single kidney.Type: GrantFiled: August 3, 2015Date of Patent: November 8, 2016Assignee: Medtronic Ardian Luxembourg S.a.r.l.Inventors: Denise Zarins, Hanson Gifford, III, Mark Deem, Douglas Sutton, Howard R.

One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel.
