Abstract
A cell culture device for use, e.g., as an artificial pancreas, featuring, in various aspects, a tightly wound spiral tube snugly fit in a cavity to form a cell culture compartment, the spiral being eccentrically offset in the cavity to reduce the volume of the compartment, a sloped passage in the body with an end of the tube extending through the passage to the innermost spiral without bending sharply, the ends of the spiral tube communicating with ports on the same side of the body, and a wall of the cavity facing the spiral and being spaced from the tube to form an end of the compartment to provide for simplified cell loading.
