PROBLEM TO BE SOLVED: To provide silk thread as a raw material of an artificial blood vessel which is sufficiently flexible and stretchable and has biocompatibility, and to provide the silk thread of medical base materials such as an artificial blood vessel and an artificial organ, which is more excellent in functionality while holding original characteristics of silk by forming a tubular structure as it is.SOLUTION: The silk thread of the medical base materials such as an artificial blood vessel and an artificial organ is formed by removing sericin constituting the sheath part of the silk thread, immersing it in pure water to perform swelling treatment and then executing false twisting.COPYRIGHT: (C)2013,JPO&INPIT【課題】柔軟性や伸縮性が十分で、生体適合性を有する人工血管の原料としての絹糸を提供し、そのまま管状構造物を形成することで絹本来の特性を保持しつつ、より機能性に優れた人工血管や人工臓器等の医療用基材の絹糸が得られることを目的とする。【解決手段】本発明に係る人工血管や人工臓器等の医療用基材の絹糸は、絹糸の鞘部を構成しているセリシンの除去を行ない、純水に浸漬して膨潤処理した後、仮撚加工を施して成ることを特徴とする。【選択図】 なし
