Multi Valve Anti-Reflux Prosthesis

A prosthesis for controlling flow through a bodily lumen, the prosthesis comprising:

• a body having a proximal portion, a distal portion and a lumen extending therethrough;
• a first valve operably connected to the body, the first valve having 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 being dosed in the absence of a second and a third pressure that are greater than a first pressure;
• and
• a second valve operably connected to the body, the second valve having 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 second valve, the distal end of the first valve extending distal to the distal end of the second valve, the second valve and the first valve controlling flow through the prosthesis.
