  • Patent number: 9089350
    Abstract: A catheter includes a flexible braided shaft having a length sufficient to access a target vessel of the body, such as a renal artery. An electrode at the catheter's distal tip is configured to ablate extravascular target tissue, such as perivascular renal nerve tissue. An electrical conductor coupled to the electrode extends along a first lumen of the shaft. A second lumen of the shaft terminates at a port arrangement on an outer surface of the shaft near the electrode. The second lumen transports a contrast media from the catheter's proximal end and through the port arrangement. The catheter may include a steering arrangement and a lubricious coating on an outer surface of the shaft, allowing a clinician to navigate the catheter through vasculature and into the target vessel without use of a separate delivery sheath or guiding catheter.
