  • Patent number: 11903811
    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 The extraction member is then withdrawn or rotated so the wires engage and draw in the filter members, after which the catheter is pushed over the conical portion of the tubular member.

  • Patent number: 11864788
    Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has an outer body and an inner body present within a lumen of the outer body. The outer body may be malleable and have a pre-set deflection or may be flexible and achieve deflection when being inserted into the epidural space. Once in the epidural space, the inner body is extended distally from the lumen of the outer body such that a distal tip on the inner body extends further into the epidural space to provide clearing to the target site without requiring further ingress of the outer body. The inner body is retracted and the clearing tool is removed. The medical lead is then inserted through the window and cleared epidural space until reaching the target site.
