Abstract

Embodiments of the present invention comprise capillary fluid transport and containment structures in which a capillarity gradient is provided in a direction other than the primary direction of fluid transport to selectively capture and transport gas bubbles. The structures may be formed with single capillary members or may include a plurality of capillaries, such as sheet capillaries joined by appropriately sized through-holes.
