A vented microcradle comprising a microfabricated enclosure designed to
maintain a human embryo or hatching in a controlled care environment, the
enclosure forming a cradle support for the human embryo or hatchling and
having a ventilation system to provide the human embryo or hatchling with
gentle fluidic ventilation via associated microfluidics. In a preferred
embodiment, the microfabricated enclosure is a picket fence structure
with a vented flooring; the vented flooring, which has a grill-like
pattern, forms part of the ventilation system in connection with
associated microfluidics.
