1. A valve for regulating fluid flow through a body vessel, the valve comprising:
- a leaflet having a valve portion moveable between a first position that permits said fluid flow in a first direction and a second position that substantially prevents said fluid flow in a second, opposite direction, the leaflet defining a plurality of pores, the valve portion having a first portion and a second portion, a first pore of the plurality of pores is disposed on the first portion, and a second pore of the plurality of pores is disposed on the second portion, wherein the first pore has a first diameter and the second pore has a second, different diameter; and
means for maintaining an axial position of the leaflet in said body vessel.
