1. device that is used for the treatment of patient'"'"'s vascular system, it comprises:

  • The permeable shell of self expandable formula elasticity, it has near-end, far-end, the longitudinal axis, and it further comprises;

    A plurality of elasticity of elongation long filaments with braiding structure, it is relative to each other fastening at near-end and far-end, be subjected to the elongation state of radial constraint, it is configured to send in microtubular through described thin braided filament, described braided filament along the length of described long filament each other radially adjoining ground from described near-end extend lengthwise into described far-end andRelaxed state with respect to the expansion of the configuration that is spherical and vertically shortens of the described state that is subjected to radial constraint, wherein said braided filament forms the permeable shell of described self expandable formula elasticity along the smooth-path from described longitudinal axis radial dilatation between described near-end and the described far-end, and be included in a plurality of openings that form between described braided filament in the described shell, the maximum is configured to and allows blood to cross described opening with the velocity flow that is lower than thrombotic threshold velocity in the described opening.
