    摘要： A method and apparatus is provided for removing material from an outer surface of a workpiece such as a catheter or other medical device. The method begins by generating a laser beam having an intensity profile and directing the laser beam onto the outer surface of the workpiece. After the laser beam is generated, its intensity profile is adjusted by a component such as a diffractive optical element (DOE) or a holographic optical element (HOE) so that material can be removed from the workpiece by ablation in a prescribed manner.

    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： Methods, devices, and systems for extracting vessel occluding material are provided. An embodiment of a vessel occluding material extractor includes a host structure, a plurality of expandable members, a slide mechanism, and a circumferential member. The host structure has an elongate axis. The expandable members are connected to the host structure arrayed radially around the elongate axis. The slide mechanism is connected to the expandable members and adjacent the host structure, and is slidable in the direction of the elongate axis. The circumferential member is connected to the expandable members between the connection of the slide mechanism and the host structure to the expandable members.
