(54) Title: METHOD AND SYSTEM FOR DELIVERING A SELF-EXPANDING STENT TO THE VENOUS SINUSES (57) : A stent delivery system includes a shaft extending from a proximal end of the system into a delivery tip at a distal end. The shaft includes a coil and a stent bed. A stent is loaded onto the stent bed and has a first portion at its distal end having a greater flexibility than a second portion at its proximal end. Sheathing is moveable over the stent bed between pre-deployed and deployed positions. The sheathing includes a flexible section at the sheathing distal end, a semi-flexible section adjacent the flexible section, and a stiff section adjacent the semi-flexible section. The delivery tip is more flexible than the combination of the stent bed, the first portion of the stent, and the flexible section of the sheathing, which is more flexible than the combination of the stent bed, the second portion the stent, and the flexible section of the sheathing.
