A folding medical device (10), comprising a plurality of metal wire strands woven into a woven metal fabric having a proximal end and a distal end (12, 14), each end having a means (18, 20) for fixing each end attached to said woven metal fabric, thereby gathering said cords and preventing fraying of the cords, said woven metal fabric having an expanded preset configuration shaped to create a restriction in a blood vessel, said expanded preset configuration being in the form of a cylindrical disc of a predetermined thickness that has at least one lumen defined by the plurality of metal cords and that extends through the thickness dimension of said disc through which blood and deformable can flow to a smaller sectional dimension for delivered to a patient's body through a channel, the woven wire mesh having a memory property is according to which the medical device tends to return to said expanded preset configuration when it is not constrained, which expanded preset configuration defines openings (26, 28) of the lumen greater than the mesh size of the braid |
