    摘要: Therapeutic agent delivery devices and methods for delivering a therapeutic agent to a target location as well as methods for determining the location of a lesion on a vessel wall are disclosed. Various embodiments disclose an expandable member comprising a drug delivery matrix for selectively delivering a therapeutic agent to a lesion on a vessel wall. The drug delivery matrix may comprise one or more sensors and an electroactive polymer for releasing the therapeutic agent. Other embodiments disclose an expandable member comprising a plurality of radially-expanding flexible walls forming a plurality of channels for selectively delivering therapeutic agent to a target area adjacent one or more of the channels. Detecting a lesion may comprise using a plurality of Hall effect sensors disposed on a distal end of a catheter.

    摘要: A biodegradable implant for iontophoretic therapeutic agent delivery is provided. The implant comprises a biodegradable battery and at least one biodegradable iontophoresis electrode assembly. The biodegradable battery comprises first and second biodegradable electrodes and a biodegradable polymer electrolyte layer between the first and second biodegradable electrodes. The biodegradable iontophoresis electrode assembly comprises a biodegradable iontophoresis electrode and a charged therapeutic agent. When the biodegradable battery is electrically connected to generate an electric current through the biodegradable iontophoresis electrode assembly, the charged therapeutic agent is delivered by iontophoresis to a target location. The charged therapeutic agent may be a scavenger for reactive oxygen species. The electrical connection of the biodegradable battery may be controlled remotely.
