Abstract: A display device is described which includes a fluid exchange device mated to the display housing. The fluid exchange device makes a fluid tight seal with the display housing and includes a sealing member which may be perforated by a conduit. The conduit provides for the flow of fluids into and away from a cavity within the display device that is used to contain a display medium. The fluid exchange device provides a fluid tight seal with the housing, and the sealing member reseals itself upon withdrawal of the conduit from the sealing member.

Abstract: A multi-zone, multifinctional graft with two or more zones that have different chemical and biological characteristics is provided. The vascular conduit that has of an inner zone that is permanently non-thrombogenic and anti-proliferative, and one or more outer zones that allow for beneficial tissue in-growth and sealing of the graft to prevent leakage. The small diameter vascular conduits of the present invention containing these different zones may be fabricated from woven or knitted Dacron, extruded porous PTFE, from polyurethane polymer, or other similar materials, and the structure of these conduits so modified as to provide these different zones. One embodiment contains an inner non-thrombogenic layer and an outer thrombogenic layer, optionally containing a growth agent. A second embodiment contains a third intermediate layer having a growth agent impregnated therein.

Abstract: A method of producing radio frequency discharge plasma film layers having a three-dimensional functional film network. The plasma film layers include a first layer, comprising a plurality of a first functional group, and a second layer, comprising a plurality of a second functional group. The employment of three-dimensional film networks with desired functional groups located either on the periphery or both the periphery and interstitial spaces of the networks provides means for significantly increasing the surface functional density.
