Prosthesis having a sleeve valve

A prosthesis for placement in a patient comprising:

• a tubular drainage stent having a passage extending longitudinally there through configured to pass only bodily matter;
• a retention structure extending from an outer surface of the passage and comprising a flexible material configured to hold the tubular drainage stent within a vessel that conveys fluid without enlarging a diameter of the passage;
• and
• a sleeve extending from an end of the tubular drainage stent and having a lumen extending longitudinally there through and communicating with the passage of the tubular drainage stent, the sleeve in response to a fluid applying a first pressure in a first direction passing the fluid through the lumen thereof, the sleeve collapsible to at least substantially close the lumen in response to a fluid applying a second pressure in a second direction;
• wherein the tubular drainage stent comprises a non-expandable tubular drainage stent.
