This disclosure is directed to extra, intra, and transvascular medical lead placement techniques for arranging medical leads and electrical stimulation and/or sensing electrodes proximate nerve tissue within a patient. This disclosure is directed to a system for implantation of an implantable medical lead within a lumen of a blood vessel within a patient for delivery of electrical stimulation to nerve tissue located adjacent to and outside of the blood vessel, the system comprising: a catheter adapted to be positioned within the blood vessel lumen adjacent the nerve tissue; an electrode configured to be advanced toward a wall of the blood vessel lumen; and a sensor configured to detect the relative positions of the nerve tissue outside of the blood vessel and the electrode within the blood vessel lumen. |
