1. A flow-reducing intraluminal stent for placement in a coronary sinus of a patient, the stent comprising:

  • a hollow central portion having first and second ends and defining a flow passage therethrough; and

    first and second expandable portions located at the first and second ends of the central portion and having respective outer edges,wherein the expandable portions are adapted to be expanded within the coronary sinus such that the outer edges widen outward with monotonically increasing diameter to engage a wall of the coronary sinus, so as to firmly affix the stent within the coronary sinus, andwherein a diameter of the flow passage is substantially fixed at a size that is predetermined prior to implantation by a structure of the central portion, thus reducing a flow of blood through the coronary sinus.
