Abstract
An artifical pancreatic perfusion device comprising a hollow fiber having a porosity ranging from about 25 Kd to about 200 Kd. The hollow fiber has one end connected to a blood vessel for receiving blood and a second end connected to a blood vessel for returning said blood. Islets of Langerhans surround the hollow fiber. The hollow fiber and islets are surrounded by a housing comprising a semipermeable membrane having a pore size small enough to offer protection to the islets and host from immune reactive substances. Further disclosed is a method for providing and regulating insulin to insulin deficient individuals.
