  • Patent number: 11414636
    Abstract: A polymer or other substrate optimized for growing cells is described, which takes the form of a micro-thin bag with gas permeable sides. Sides of the bag can be held at a fixed distance from one another with a multitude of tiny micropillars or other spacers extending between them, keeping the bag at a predetermined thickness and preventing the bag from collapsing and the sides from sticking together. In other embodiments, the sides may be held apart by gas pressure alone. A 0.01 ?m to 1000 ?m parylene or other biocompatible coating over the bag outsides controls the permeability of the bag material and provides a bio-safe area for cell growth. An alternate configuration uses open-cell foam with skins coated with a biocompatible coating. Tubes going into multiple bags can be connected to a manifold that delivers gaseous oxygen or removes carbon dioxide and other waste gases.

  • Patent number: 11400307
    Abstract: Embodiments of the present disclosure are directed to a wearable phototherapy eye device. In an example, phototherapy can be controlled by varying an emission property of light emitted from the wearable phototherapy eye device to a user eye. In particular, the wearable phototherapy eye device includes a light source oriented to emit the light towards the user eye. The wearable phototherapy eye device also includes controls, such as electrical, mechanical, and/or electro-mechanical controls, to vary the emission property of the light based on an emission target associated with a sleep phase.
