Manufacturing process of an occlusion device

摘要

An implant (1) is made from resorbable filaments (2), knitted e.g. on five needles (3), to form an elongated tube with stitches crossing inside it. The number and thickness of the filaments, which can be treated with substances that promote occlusion and/or degeneration of the treated body duct, are determined so that the implant's resorption time coincides with that of the duct once occlusion has taken place.
