    摘要： The invention generally relates to internal (e.g., implantable, insertable, etc.) drug delivery devices which contain the following: (a) one or more sources of one or more therapeutic agents; (b) one or more first electrodes, (c) one or more second electrodes and (d) one or more power sources for applying voltages across the first and second electrodes. The power sources may be adapted, for example, to promote electrically assisted therapeutic agent delivery within a subject, including electroporation and/or iontophoresis. In one aspect of the invention, the first and second electrodes are adapted to have tissue of a subject positioned between them upon deployment of the medical device within the subject, such that an electric field may be generated, which is directed into the tissue. Furthermore, the therapeutic agent sources are adapted to introduce the therapeutic agents into the electric field. In another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of ion-conductive polymers and one or more types of charged therapeutic agents. In yet another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of electrically conductive polymers and one or more types of charged therapeutic agents.

    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.
