1. A method of manufacturing a braided implant for an aneurysm, the method comprising:

  • distally sliding a hypotube over a proximal end of the braided implant and onto an attachment pin;

    inverting the braided implant into itself by proximally moving a distal end of the braided implant over a distal end of the hypotube and forming a folded edge of the braided implant;

    radially aligning a plurality of clips of an expansion ring about the folded edge, each clip comprising an opening;

    gripping an inner surface of a first clip of the plurality of clips and attaching the first clip onto the braided implant by inserting an opening of the first clip around and through a first pair of crosses;

    rotating the attachment pin and repeating the step of attaching for each subsequent clip onto the braided implant by inserting an opening of each subsequent clip around and through a respective subsequent first pair of crosses of the braided implant and then through a respective subsequent second pair of crosses of the braided implant;

    welding the clips along a length of each respective clip and an inner surface of the braided implant;

    extending the attachment pin past the plurality of clips, repositioning the hypotube onto the attachment pin; and

    pulling back on the braided implant such that the hypotube presses against the clips thereby causing the braided implant to invert onto itself.
