Abstract

Hypertension is treated in a patient by implanting an ablation stent in a renal artery of the patient. Energy is transmitted to the ablation stent to induce heating of the ablation stent, which causes ablation of a renal sympathetic nerve present on the outside of the portion of the renal artery comprising the ablation stent. A preferred ablation stent is in the form of an N-turn coil of an electrically conductive wire forming a meander structure. The respective ends of the wire are electrically connected to each other.
