1. A vascular flow-reducing implant, comprising:
a self-expanding tubular structure configured to form a flow reducing restriction when self-expanded within a vascular lumen;
opposed open end sections defined by the tubular structure having uncompressed end diameters; and
a throat section forming said flow-reducing restriction defined between the opposed open end sections and having an uncompressed throat diameter less than the uncompressed end diameters;
wherein the throat section is configured such that the throat diameter does not reduce by more than about 35% when the end sections are compressed by up to about 50%.
