1. An apparatus, comprising:

  • a catheter comprising a flexible shaft having a proximal end, a distal end, and a length sufficient to access a patient'"'"'s renal artery relative to a percutaneous access location;

    a conductor arrangement extending along the shaft between the proximal and distal ends of the shaft;

    an electrode provided at the distal end of the shaft, coupled to the conductor arrangement, and dimensioned for deployment within the renal artery; and

    a deformable cover provided at the electrode and comprising a force-activatable conduction apparatus, the cover configured to prevent conduction of electrical energy through the cover in the absence of cover deformation, and to conduct electrical energy only through a region or regions of the cover subject to deformation, the electrical energy sufficient to ablate perivascular renal nerves proximate the deformed region or regions of the cover.
