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.

Abstract
A narrowing intraluminal stent is disclosed and comprises a hollow body and a flow passage therethrough, the hollow body designed for intraluminal placement and having at least one portion of an inner cross sectional dimension smaller than the cross sectional dimension of the lumen, so as to artificially narrow a passage through the body lumen. A method of artificially narrowing a passage through a body lumen using the stent is also disclosed.
