Chamber assembly for premature fetus

A growth chamber for use with a fetal chamber assembly, the growth chamber being configured to receive a first fluid therein and a fetus therein, the growth chamber comprising:

• a top membrane;
• a bottom membrane opposite the top membrane;
• a growth membrane spaced away from the bottom membrane, the bottom membrane being disposed between the growth membrane and the top membrane;
• and a fluid pocket defined between the growth membrane and the bottom membrane, the fluid pocket being configured to receive a second fluid therein, wherein the fetus is configured to be received between the top membrane and the bottom membrane, and wherein the growth chamber has a first configuration and a second configuration, where when the growth chamber is in the first configuration, a first growth volume is defined between the top membrane and the bottom membrane, and a first pocket volume is defined within the fluid pocket between the growth membrane and the bottom membrane, and when the growth chamber is in the second configuration, a second growth volume is defined between the top membrane and the bottom membrane, and a second pocket volume is defined within the fluid pocket between the growth membrane and the bottom membrane, the first growth volume being different from the second growth volume, and the first pocket volume being different from the second pocket volume.
