Abstract
Apparatus is provided including a housing, configured for insertion into a body of a subject, one or more oxygen reservoirs disposed within the housing, at least one layer of functional cells, disposed within the housing, and gaseous oxygen disposed within the one or more oxygen reservoirs. The apparatus is arranged to permit passage of the gaseous oxygen from the one or more oxygen reservoirs to the functional cells. The one or more oxygen reservoirs define first and second air gaps, the first air gap is configured to receive oxygen in a first concentration, and the second air gap is disposed adjacent to the layer of functional cells and stores the oxygen in a second concentration that is lower than the first concentration. Other applications are also described.
