An aneurismal sack deflator is disclosed including a body having an aneurismal sack neck closure surface. An internal surface defines at least a portion of a fluid passageway, with the internal surface configured to provide a Venturi effect to thereby reduce fluid pressure in the fluid passageway. A semi-permeable region is in fluid communication with the fluid passageway and the aneurismal sack. The semi-permeable region permits first blood components to pass therethrough out of the aneurismal sack and into the fluid passageway when the lower surface is under reduced pressure and does not permit second blood components to pass therethrough.
