    摘要: An endoprosthesis includes an expandable tubular body defined by a plurality of struts. In some embodiments, the expandable tubular body includes a bioerodible metal that has at least a first surface region and a second surface region. The first and second surface regions can have different surface oxide compositions. In some embodiments, the first portion has a thermally altered microstructure and the second portion has a wrought microstructure. The thermally altered microstructure can be a cast microstructure comprising dendritic grains. The first portion forms at least a portion of an outer surface of the expandable tubular body. In some embodiments, the expandable tubular body includes iron or a bioerodible iron alloy and at least one surface of the expandable tubular body includes a substantially uniform coating of iron(III) oxide.

    摘要: A catheter tip may be coupled to a catheter shaft. The catheter tip may include markers, such as radiopaque markers and MRI markers, securement hubs, recessed portions, a radiused tip, and varying axial flexibility. The catheter tip may be a molded tip, and the markers may be insert molded. Recessed portions and raised securement hubs may be formed during the molding process. The raised hubs may be integrally formed and made from the same material as the catheter tip.

    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: An apparatus, system and method of a resonator device with an adjustable capacitor for allowing the resonance frequency (F) of the resonator device to continue to be matched to the Larmor frequency of the MRI system. The resonator device includes an inductor coil, a conductive member, a sleeve having first and second sockets that receive at least portions of the inductor coil and the conductive member as electrodes to provide a capacitor structure. Dielectric material can be positioned between at least the first and second sockets, where changes in the cross sectional area defined by the induction coil cause changes in the capacitance value (C) as one or more of the electrodes move within the socket. Changes in the inductance and the capacitance values allow for the resonance frequency (F) of the resonator device to continue to be matched to the Larmor frequency of the MRI system.
