    摘要: The present invention relates generally to medical devices with therapy eluting components and methods for making same. More specifically, the invention relates to implantable medical devices having at least one porous layer, and methods for making such devices, and loading such devices with therapeutic agents. A mixture or alloy is placed on the surface of a medical device, then one component of the mixture or alloy is generally removed without generally removing the other components of the mixture or alloy. In some embodiments, a porous layer is adapted for bonding non-metallic coating, including drug eluting polymeric coatings. A porous layer may have a random pore structure or an oriented or directional grain porous structure. One embodiment of the invention relates to medical devices, including vascular stents, having at least one porous layer adapted to resist stenosis or cellular proliferation without requiring elution of therapeutic agents. The invention also includes methods, devices, and specifications for loading of drugs and other therapeutic agents into nanoporous coatings.

    摘要: Methods and devices for applying hemodynamic patterns to human/animal cells in culture are described. Hemodynamic flow patterns are measured directly from the human circulation and translated to a motor that controls the rotation of a cone. The cone is submerged in fluid (i.e., cell culture media) and brought into close proximity to the cells. Rotation of the cone creates time-varying shear stresses. This model closely mimics the physiological hemodynamic forces imparted on endothelial cells in vivo. A TRANSWELL coculture dish (i.e., a coculture dish comprising an artificial porous membrane) may be incorporated, permitting two, three, or more different cell types to be physically separated within the culture dish environment. In-flow and out-flow tubing may be used to supply media, drugs, etc. separately and independently to both the inner and outer chambers. The physical separation of the cell types permits each cell type to be separately isolated for analysis.
