Claim Text:
1. An apparatus, comprising: a catheter comprising a flexible shaft having a proximal end, a distal end, a length, and a lumen arrangement extending between the proximal and distal ends, the length of the shaft sufficient to access a renal artery of a patient relative to a percutaneous access location; a balloon provided at the distal end of the shaft and fluidly coupled to the lumen arrangement, the distal end of the shaft and the balloon dimensioned for deployment within the renal artery, the balloon comprising: an electrical conductor extending at least partially along the shaft and terminating proximate or within the balloon body, the electrical conductor coupled to an electrode positioned within the balloon body and configured to conduct electrical energy received from an external energy source to at least the circumferential section of the balloon body sufficient to ablate perivascular renal nerve tissue proximate the circumferential section; and a cooling arrangement configured for at least one of receiving a thermal transfer fluid from the lumen arrangement and facilitating perfusion of blood passing through the renal artery to cool the balloon body during ablation of the perivascular renal nerve tissue.
