1. An apparatus configured to change a geometry of a blood vessel in contact with a nerve, the apparatus comprising:
a body portion having a proximal end and a distal end;
an anchor element disposed on at least one of said proximal end and said distal end; and
one or more marker elements disposed on said body portion;
said body portion comprising at least two wires wrapped about one another to form a braided wire, the body portion being sized and shaped to change the geometry of the blood vessel upon insertion of the apparatus into the blood vessel to no longer contact the nerve, and being configured to have a rigidity and a length, the rigidity and length selected based on a length of a curvature in the blood vessel and a diameter of the blood vessel, the rigidity controlled by one or more of the number of wires of the braided wire, a thickness of the wires, and a material of the wires, the rigidity being sufficient to retain the changed geometry of the blood vessel with the apparatus positioned therein and reduce or eliminate blood vessel pulsation.
