Cell culture device
First Claim
1. A cell culture device comprising,a body having a generally circular fluid tight cavity therein,said body having an inlet and an outlet anda semi-permeable tube wrapped about itself to form coils in said cavity, said coils forming a flat spiral about a central axis,the interior of said tube providing a fluid flow path for communicating with a biological fluid source,said flat spiral coils positioned in said cavity between a bottom wall and a cover plate to form a cell culture compartment therebetween.said tube being tightly wound in said flat spiral such that adjacent coils thereof touch each other to substantially eliminate dead space between said coils,the ends of said tube extending through said inlet and said outlet, andsaid cavity being shaped to entirely surround said coils and being just wide enough and high enough to accommodate said tightly wound coils, to further reduce dead space.

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.
