1. A device which is implantable in a blood vessel to block the flow of blood in at least one direction through a lumen of that blood vessel, said device comprising:

  • a) a blood vessel engaging portion comprising a cylindrical frame initially disposable in a radially collapsed configuration such that said device may be passed into the lumen of said blood vessel, and subsequently expandable to an operative configuration wherein the cylindrical frame will frictionally engage a wall of the blood vessel to hold the device in a substantially fixed position within said blood vessel lumen, a hollow channel extending longitudinally through the cylindrical frame when the cylindrical frame is expanded to its operative configuration; and

    , b) a lumen blocking portion comprising a flexible sock member that has an open end and a substantially closed end, the open end of said flexible sock member being affixed to the cylindrical frame such that when the cylindrical frame is disposed in its operative configuration within a blood vessel, blood flowing through the blood vessel will enter the sock member and will be substantially blocked by the sock member from flowing through the hollow channel of the cylindrical frame.
