A prosthesis and a method of controlling flow through a bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a first valve and a second valve operably connected to the body. The first valve has a proximal portion, a distal portion, a distal end extending distally relative to the proximal portion of the body and a lumen extending through the first valve. The first valve is closed in the absence of a second and third pressure that are greater than a first pressure. The second valve has a proximal portion, a distal portion, a distal end extending distally relative to a proximal portion of the body and a lumen extending through the second valve, the distal end of the first valve extending distal to the distal end of the second valve.
