Abstract
A system for the treatment of Alzheimer's disease is provided by moving cerebrospinal fluid containing particles know to contribute to onset of Alzheimer's disease from a source of cerebrospinal fluid to the stomach or bladder, where the particles are safely digested by gastric acid or excreted, the system including an implantable pump, an inlet catheter, an outlet catheter, and a one-way valve. The system further includes at least one filter to filter harmful particles from the cerebrospinal fluid and return the filtered cerebrospinal fluid back to the source of cerebrospinal fluid, where the harmful particles blocked by the filter may be rinsed off the filter and transported to the stomach or bladder.
