<p>Provided is a vascular occlusion device which can effectively block blood flow and blood pressure to a blood vessel loss part while not blocking blood flow and blood pressure to an adjacent blood vessel structure. The vascular occlusion device can comprises a tubular member having variable porosity areas along the length. The tubular member can be composed of multiple filaments, wherein the multiple filaments has different cross sectional shapes corresponding to the length of the filaments which are indexed for variable porosity areas according to the length of the tubular member.</p> |
