Patent Images
1. A device for removably placing cells in a microflowchamber of a microphysiometer comprising:
- (a) an outer sleeve having a top and bottom opening wherein the bottom opening of said outer sleeve is covered with a porous membrane;
(b) an inner sleeve fitting within the outer sleeve and having a top and bottom opening wherein the bottom opening of said outer sleeve is covered with a porous membrane; and
(c) a spacer means between the porous membranes of the inner and outer sleeves which defines and opening and which together with the porous membranes defines a porous microchamber wherein cells are maintained in the porous microchamber when liquid flows through the porous membranes wherein the porous microchamber has a volume of between 10 nanoliters and 10 microliters.

Abstract
This invention encompasses porous microchambers which contain cells and permit liquid to flow in and out of the chamber while retaining cells within the chamber. These porous microchambers serve as disposable devices for placing cells in a microflowchamber so that properties of the cells within the porous microchamber can be measured.
