Abstract
Methods for therapeutic renal denervation are disclosed herein. One aspect of the present application, for example, is directed to methods that block, reduce and/or inhibit renal sympathetic nerve activity to achieve a reduction in central sympathetic tone. Renal sympathetic nerve activity may be altered or modulated along the afferent and/or efferent pathway. The achieved reduction in central sympathetic tone may carry several therapeutic benefits across many disease states.
Claims21
A method for treating a hypertensive human patient, the method comprising:
- intravascularly positioning an energy delivery element within a renal artery of the hypertensive patient;
- modulating a renal nerve along the renal artery via energy from the energy delivery element at a plurality of locations along a wall of the renal artery;
- and
- removing the energy delivery element from the patient after treatment,
- wherein the patient achieves a decrease in blood pressure of at least 10 mm Hg by six months after modulation of the renal nerve.
