1. A method of treating pulsatile tinnitus (PT) in a subject which comprises:
providing a stent that is braided and self-expanding,
the stent having a proximal end, a distal end, and a tubular flexible body between the proximal end and the distal end, with the same diameter at the proximal and distal end, the tubular flexible body comprising a wire arrayed in a cellular pattern,
wherein the tubular flexible body has a higher degree of stiffness in a first section of the tubular flexible body than in a second section of the tubular flexible body,
wherein the tubular flexible body has different zones of outward force, a length of between about 40 mm and about 80 mm, is configured to expand to conform to an ovoid or triangular shape of vessel of a cerebral venous sinus system of the subject, to secure itself to surrounding walls of the vessels, to be retrievable or re-sheathable and to be implanted in a stenosis in a selected vessel of the vessels of the cerebral venous sinus system,
inserting a guide wire and a flexible delivery catheter through an incision in the femoral, basilic, or internal jugular vein, the stent being contained within a lumen of the delivery catheter;
guiding the stent through one or more of the vessels of the cerebral venous sinus system in a collapsed configuration on the guide wire to the stenosis; and
releasing the stent from the guide wire at the stenosis in the selected vessel to allow the stent to self-expand, to alleviate the stenosis by forcing a surrounding narrowed segment of the selected vessel to expand, and to secure itself to the surrounding narrowed segment of the selected vessel to and maintain the patency of the selected vessel to treat the PT.
