  • EMBOLUS BLOOD CLOT FILTER REMOVAL SYSTEM AND METHOD
    Publication number: 20180008393
    Abstract: A blood filter extraction system for extracting a blood filter from within a blood vessel. The system includes an extraction wire, or plurality of such wires, positioned within an elongated tubular member. A plurality of extraction wires coupled to the distal end of the extraction member each include a hook for engaging filter members. Alternatively, the extraction wires may be one or more wires configured in a helical shape which engage filter members when the extraction member is rotated. The system may also include an elongated tubular member with the distal end having a conical shape. To extract a filter, the extraction wires are then pushed out of the tubular member and into the filter members. The extraction member is then withdrawn or rotated so the wires engage and draw in the filter members, after which the catheter is pushed over the conical portion of the tubular member.
