PROBLEM TO BE SOLVED: To provide methods and apparatuses for restoring at least partial blood flows in occluded cerebral arteries.SOLUTION: A medical device 10 for blood flow restoration and/or for use as an implantable member in a human vessel includes, a self-expanding member 16, a guidewire 12, and a connection mechanism 14. The self-expanding member includes a plurality of cells and filaments having specific ranges of thicknesses, widths and heights. The self-expanding member can take on a volume-reduced coiled form with overlapped edges, and can generate optimal radial forces against a vessel wall and/or thrombus when deployed and expanded.SELECTED DRAWING: Figure 1 |
