FINE BLOOD VESSEL OCCLUSION DEVICE WITH FIBERS

摘要

PROBLEM TO BE SOLVED: To provide a occlusion device which can be used in a very fine blood vessel at a distal in the vascular system. SOLUTION: This occlusion device 200 comprises a) at least one holder 102 with at least one passage 106 which extends along the axis 110 of the holder in the axial direction between both ends of the axis, and b) a plural number of fibers 104 which are the longest. These fibers 104 run through at least one part of at least one passage 106, and the ratio of the longest length of the fibers 104 to the length 108 in the axial direction of the holder is at least 2:1.
