    摘要: A method for forming a resistive switching device. The method includes providing a substrate having a surface region and forming a first dielectric material overlying the surface region of the substrate. A first wiring structure overlies the first dielectric material. The method forms a first electrode material overlying the first wiring structure and a resistive switching material comprising overlying the first electrode material. An active metal material is formed overlying the resistive switching material. The active metal material is configured to form an active metal region in the resistive switching material upon application of a thermal energy characterized by a temperature no less than about 100 Degree Celsius. In a specific embodiment, the method forms a blocking material interposing the active metal material and the resistive switching material to inhibit formation of the active metal region in the resistive switching material during the subsequent processing steps.

    摘要: Described herein are implantable medical devices useful in treating vascular conditions such as restenosis. In one embodiment, stents are described in which a combination of bioactive agents is described for local delivery in the vasculature. The combination of bioactive agents comprises at least one compound capable of inhibiting smooth muscle cell proliferation and at least one compound capable of mitigating MCP- and/or TF induction. For example, a compound capable of inhibiting smooth muscle cell proliferation is a mTOR inhibitor and a compound capable of mitigating MCP-1 and/or TF induction is a corticosteroid.

    摘要: The apparatus and methods of the present invention in a broad aspect provide novel multiple bioactive agent eluting stents for treating vascular diseases and conditions. Controlled elution of bioactive agents is achieved by the presence of the bioactive agents themselves. One or more characteristics of the bioactive agents cause variations in elution rates or profiles or the other bioactive agents.
