Abstract:
An intravascular catheter for nerve activity ablation and/or sensing includes one or more needles advanced through supported guide tubes (needle guiding elements) which expand to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the extra-luminal tissue including the media, adventitia and periadvential space. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall. Electrodes at the distal ends of the guide tubes allow sensing of nerve activity before and after attempted renal denervation. In a combination embodiment ablative energy or fluid is delivered to ablate nerves outside of the media.

Claim (Index 1):
A catheter for sensing the activity from nerves outside of a lumen of a target vessel of a human body comprising:\n a catheter body having a distal end for insertion into a patient, a proximal end for controlling the movement of at least one needle, and a central axis extending in a longitudinal direction; a connector configured to connect to external electronic equipment outside of a proximal end of the catheter, the external electronic equipment having a sensing subsystem configured for sensing local nerve activity within the human body; at least one needle guiding element adapted to expand outwardly from the catheter body toward the interior wall of the target vessel, the needle guiding element including an electrode at its distal end; at least one needle, the needle, the needle adapted to be advanced outwardly, guided by the at least one needle guiding element to penetrate and advance through an interior wall of the target vessel into the tissue outside of the lumen of the target vessel; and at least one wire for conducting electrical signals between the at least one electrode at the distal end of the at least one guiding element and the connector for communicating with said external electronic equipment.
