The present invention provides a system for treating a mammalian patient having obstructive sleep disordered breathing, e. Such methods utilize novel compositions, including but not limited to extraembryonic cytokine secreting cells, including, but not limited to, amnion-derived multipotent progenitor cells, conditioned media derived therefrom, cell lysates derived therefrom, and cell products derived therefrom, each alone or in combination. The terminal has a contacting plate exposed in the receiving room. First and second pistons are guided respectively in a displaceable manner in the subchambers and can be displaced therein by a swash plate.
