ABSTRACT:
An intravascular device having a chamber for containing transplanted cells. The device is adapted to be implanted in a wall of a blood vessel with a porous chamber-forming wall of the chamber providing an interface between the cells in the chamber and the blood in the vessel. The chamber-forming wall has a pore size permitting continuous diffusion of hormonal components therethrough but blocking the diffusion of cells. The device may also be implanted between an artery and a vein in a wall of each so as to act as a sieve between the artery and vein subject to the differential pressure therebetween. A method is also disclosed for employing the device to introduce hormonal components into the blood stream.
