Abstract: Medical devices configured to provide a controllable release of a drug, particularly for use in pleural effusion therapy. The medical devices comprise a component including a carrier-drug complex, wherein the carrier-drug complex comprises one or more molecules of a drug reversibly bound to a porous carrier. The present disclosure also relates to methods of making the carrier-drug complexes and medical devices described herein.

Abstract: The present invention relates to controlling the surface characteristics of an image forming device component. The device may include photoconductive elements or non-photoconductive elements such as rollers or blades. The surface characteristics such as texture may be controlled by introducing a coating to the surface of a component or modifying the mechanical properties of the component surface while in a physically stressed state. This may then be followed by release of such stress and development of strain at the component surface.
