  • Patent number: 10806618
    Abstract: A deployment system for a self expanding stent includes a catheter assembly with a tip attached to a distal end segment of an elongate tube. The tip includes a proximal portion molecularly joined to a distal portion, which has a lower durometer hardness than the proximal portion. The proximal portion includes an anchor surface in contact with the distal portion, and oriented perpendicular to a central axis of the elongate tube. The elongate tube may be formed from a thermosetting polyimide, and the overmolded tip may be made from two different colored and different hardnesses of polyether block amide material. The tip is overmolded onto an untreated external surface of the elongate tube.
    Type: Grant

  • Publication number: 20060021562
    Abstract: A method and kit for mounting a flag to a flagpole includes providing a mounting kit having a flagpole, a sealed bearing with an inside diameter dimension selected to correspond to an outside diameter dimension of the flagpole; a tie; a flexible coupler and a flag with a sufficiently stiff pole-side hemmed edge extending between a top flag eyelet and a bottom flag eyelet to help hold the pole-side hemmed edge straight for full flag display purposes; and then, following the instructions within the kit, mounting the flagpole to a stationary surface, securing the sealed bearing to a top portion of the flagpole, passing the tie through the top one of the pair of flag eyelets to secure a top portion of the flag to the bearing with the tie; and securing the flexible coupler between the bottom one of the pair of eyelets and the flagpole, thereby mounting the flag for free rotation about the flagpole in windy conditions.
