Claims
- 1. A method of removing an immunologically reactive compound from the blood of a living mammal, which comprises;
- removing the whole blood from a living mammal in an extra corporeal, closed circuit;
- separating a portion of the blood plasma from the whole blood within the extra corporeal circuit, by passage of the portion through an ultrafilter, said ultrafilter permitting the passage of plasma with dissolved immunologically reactive compounds, but not permitting the passage of solids within said blood;
- reacting the separated immunologically reactive compound with its homolog bound to the surface of a lipid vesicle;
- separating the resulting lipid vesicle complex from the plasma;
- passing the blood plasma minus lipid vesicle bound immunologically reactive compound to the whole blood in the extra corporeal stream; and
- passing the whole blood back to the mammal's circulatory system.
- 2. The method of claim 1 wherein the reactive compound is an antigen and the homolog in an antibody.
- 3. The method of claim 2 wherein the antibody is a monoclonal antibody.
- 4. The method of claim 1 wherein the reactive compound is an antibody and the homolog is an antigen.
- 5. The method of claim 1 wherein the lipid vesicles encapsulate a tracer compound.
- 6. The method of claim 1 wherein the ultrafilter comprises a hollow fiber.
- 7. The method of claim 1 wherein there are a plurality of different reactive compounds to be removed and a plurality of different homologs are employed, bound to lipid vesicles.
