A composition which can be used as an organic water/oxygen barrier material, an OLED display device and manufacturing method thereof are disclosed. The composition includes: 15-25 wt % of parylene, 15-25 wt % of polyvinyl chloride, 5-15 wt % of acetone, 5-15 wt % of trichloroethylene, 10-20 wt % of polyvinyl acetate, 5-15 wt % of polyvinyl alcohol, 0-5 wt % of SiO.sub.2 nanoparticles, and 8-12 wt % of an organic solvent, wherein all weight percent values are based on the total weight of the composition. When a water/oxygen barrier layer fabricated by the composition is disposed between a luminescent layer of OLED and a light extraction layer, water vapor and oxygen gas can be prevented from entering the OLED luminescent layer, thereby prolonging the service life of the OLED luminescent layer.

Medical devices such as stents, stent grafts, and balloon catheters include a coating layer applied over a modified exterior surface of the medical device. The modified exterior surface comprises an exterior surface of the medical device subjected to a surface modification that decreases a surface free energy of the exterior surface before application of the coating layer an exterior surface. The coating layer comprises a hydrophobic therapeutic agent and at least one additive. The modified exterior surface may affect the release kinetics of the drug from the device, the crystallinity of the drug layer, the surface morphology of the coating and particle shape, or the particle size of drug of a therapeutic layer in the coating layer. For example, the effects caused by the modified exterior surface may increase the retention time and amount of therapeutic agent in tissue.

Described herein are devices used to treat high intraocular pressure and glaucoma. An example device includes a plate comprising a first surface opposite a second surface. The first surface includes a series of fluid channels. The device also includes a first coating on the first surface and a second coating on the second surface. The device is configured to lower intraocular pressure by draining aqueous humor from an anterior chamber to subconjunctival space of a patient's eye.
