Claim Text:
1. 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 closed in an absence of a second pressure in a first direction and a third pressure in a second direction that are greater than a first pressure, the third pressure being greater than the second 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 in a first configuration of the second valve 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 distal end of the first valve extends distal to a distal end of the body in a first configuration of the first valve, the first valve being closable on itself so that walls of the first valve defining the first valve lumen contact each other at the distal portion and the distal end of the first valve when the first valve is closed and extending distal to the distal end of the body, the second valve is an inverting valve wherein the distal end of the second valve extends proximally in a second, inverted configuration of the second valve in response to the third pressure, the second valve and the first valve controlling flow through the prosthesis to allow flow in the first direction and the second direction through the prosthesis in response to the second pressure and the third pressure.
