ABSTRACT:
An in-vivo bioreactor device producing a dialysis effect by acting within the gastrointestinal tract for the removal of undesirable concentrated intestinal or blood substances or metabolites is disclosed. The ingestible device is comprised of a body wall that surrounds an internal compartment. Along the wall of the shell are openings located around the periphery that allow bodily fluids to enter and exit device. The wall of the device is comprised in whole or at least in part of materials that are impermeable to the passage of external fluids and maintains its physical and chemical integrity in the environment of use during its activity. Semi-permeable membranes located either internally or externally of the device are able to withstand all physiological temperatures and pH and act in a similar manner to dialysis membranes that are used for the separation of substances in suspensions, solutions, tissue cultures, etc. Treatment materials, including fixing agents that act in a similar manner to ion exchange resins, biologically active agents including proteins, enzymes, or live bacteria, and medicinal agents, can be placed in the internal cavity of the device for the treatment of various conditions.
