1. A medical device comprising:

  • a guidewire having a proximal end and a distal end;

    a connection mechanism; and

    a self-expanding member attached to the distal end of the guidewire via the connection mechanism, the self-expanding member being non-detachable from the guidewire, wherein the self-expanding member has a mesh configuration and comprises;

    a proximal portion having a first plurality of cells, the proximal portion being tapered along a longitudinal portion of its length; and

    a distal portion having a second plurality of cells, the distal portion forming a generally tube-like configuration having a central, longitudinal axis; and

    wherein the first plurality of cells comprises filaments having a filament thickness of between 0.045 mm and 0.080 mm, and a filament width of between 0.040 mm and 0.090 mm;

    wherein the second plurality of cells comprises filaments having a filament thickness of between 0.040 mm and 0.075 mm, and a filament width of between 0.038 mm and 0.082 mm;

    wherein the self-expanding member has a radial force measurement greater than or equal to 0.0010 N/mm; and

    wherein a plurality of independent filament ends are bent and project distally and radially inwardly toward the central, longitudinal axis.
