    摘要: In accordance with an aspect of the invention, implantable or insertable medical devices are provided that comprise (a) a substrate and (b) a porous layer comprising close packed spherical pores disposed over the substrate. The porous layer may also comprise a therapeutic agent. In another aspect, the present invention provides methods of forming implantable or insertable medical devices. These methods comprise forming a predecessor structure that comprises (i) a substrate over which is disposed (ii) an assembly of microspheres. This assembly of microspheres is then used as a template for the formation of a porous layer, which may be subsequently loaded with a therapeutic agent.

    摘要: According to an aspect of the present invention, at least one ionic therapeutic agent is delivered from an implantable or insertable medical device that comprises an ion-conductive polymeric region that is disposed on a metallic region. The metallic region is in electrical contact with a dissimilar metallic region, such that a galvanic current is generated by the dissimilar metals when the device is implanted or inserted into a patient. Delivery of the ionic therapeutic agent from the ion-conductive polymeric region may be, for example, either accelerated or retarded by the galvanic current. According to another aspect of the present invention, implantable or insertable medical devices are provided which comprise: (a) a first metallic region having a first corrosion potential, (b) a second metallic region in electrical contact with the first metallic region and having a second corrosion potential that is greater than the first corrosion potential, and (c) a solid ion-conductive polymeric region, comprising an ion conducting polymer and an ionic therapeutic agent, disposed on the first metallic region, the second metallic region, or both.

    摘要: According to an aspect of the present invention, implantable or insertable blood-contacting devices are provided, which contain one or more release regions that release nitric oxide and one or more anti-restenotic agents. The release region contains one or more polymeric components. The release region also optionally contains one or more inorganic components. Nitric oxide producing groups may be attached to the polymeric component(s), to the optional inorganic component(s), or both. The one or more anti-restenotic agents may be admixed with the polymeric and optional inorganic components, attached to the polymeric component(s), attached to the optional inorganic component(s), or a combination thereof.
