    摘要： Medical devices that are visible by magnetic resonance imaging (MRI), and optionally, other imaging techniques, are described. In some embodiments, a medical device adapted for insertion into the body includes an elongated shaft and an electrically conductive path extending spirally about a portion of the shaft. The conductive path is capable of being connected to a current source. The medical device can further include one or more contrast agents (such as MRI contrast agents, radiopaque materials, and/or ultrasound visible materials), which can be arranged in a predetermined manner.

    摘要： A catheter assembly comprises a catheter shaft having a proximal region a distal region and a rotational seal therebetween. The rotational seal comprises a first component fixedly engaged to the proximal region and a second component fixedly engaged to the distal region. The components engaged in an overlapping arrangement. The rotational seal is actuatable between a non-activated and activated states. In the non-activated state the first component and the second component are separated by a gap which provides for the distal region of the catheter shaft to be rotatable relative to the proximal region. In the activated state at least a portion of the first component and the second component being sealingly engaged together such that distal region is made static relative to the proximal region.

    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.
