    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： Implantable medical devices having anti-restenotic coatings are disclosed. Specifically, implantable medical devices having coatings of certain NF-kappaB inhibitors, particularly certain dialkyl fumarates, are disclosed. Dimethyl fumarate is a particularly preferred dialkyl fumarate. The anti-restenotic medical devices include stents, catheters, micro-particles, probes and vascular grafts. Intravascular stents are preferred medical devices. The medical devices can be coated using any method known in the art including compounding the dialkyl fumarate with a biocompatible polymer prior to applying the coating. Moreover, medical devices composed entirely of biocompatible polymer-dialkyl fumarate blends are disclosed. Additionally, medical devices having a coating comprising at least one dialkyl fumarate in combination with at least one additional therapeutic agent are also disclosed. Furthermore, related methods of using and making the anti-restenotic implantable devices are also disclosed.

    摘要： A system for treating atherosclerotic cardiovascular disease and cardiac valve dysfunction comprises delivering one or more calcium chelating agents locally to a treatment site. One aspect of the invention provides a method including delivering a nano-particulate calcium chelating agent into a vascular wall. Another aspect of the invention provides a method and device for forming a sealed chamber around a cardiac valve, releasing one or more calcium chelating agents into the sealed chamber and decalcifying a cardiac valve in need thereof.
