Title (EN) BIOLOGICAL IMPLANT
(FR) IMPLANT BIOLOGIQUE
(JA) 生体インプラント
Abstract:
(EN) Provided is a biological implant that is capable of exerting a strong binding ability to a biotissue and sustaining an appropriate strength according to an application site after embedding in a living body, and scarcely peels off from a macropore skeleton part of a micropore skeleton part. The biological implant comprises a macropore skeleton part constituting macro pores and a micropore skeleton part constituting micropores, said micropores having a smaller pore size than the macropores, characterized in that: the macropore skeleton part is substantially free from pores; the micropore skeleton part is formed on the surface of the macropore skeleton part; the macropore skeleton part and the micropore skeleton part are formed of the same engineering plastic; and the macropore skeleton part is formed of a single material.
(FR) La présente invention concerne un implant biologique qui est capable de conférer une forte capacité de flexion à un tissu biologique et de conserver une force adaptée en fonction d'un site d'application après son intégration dans un corps humain, et qui se décolle rarement d’une partie squelette macroporeux d’une partie squelette microporeux. L’implant biologique comprend une partie squelette macroporeux constituant des macropores et une partie squelette microporeux constituant des micropores, lesdits micropores ayant une taille de pores inférieure aux macropores, caractérisé en ce que : la partie squelette macroporeux est dépourvue de pores ; la partie squelette microporeux est formée sur la surface de la partie squelette microporeux ; la partie squelette macroporeux et la partie squelette microporeux sont formées du même plastique d’ingénierie ; et la partie squelette macroporeux est en un seul matériau.
(JA)  生体内に埋設した後に生体組織と強固な結合能力を発揮すると共に適用部位に応じた適度な強度を確保することができ、ミクロ気孔骨格部のマクロ気孔骨格部からの剥離が生じ難い生体インプラントを提供すること。マクロ気孔を形成するマクロ気孔骨格部と、前記マクロ気孔よりも気孔径の小さいミクロ気孔を形成するミクロ気孔骨格部と、を有する生体インプラントであって、前記マクロ気孔骨格部は実質的に気孔を含まず、前記ミクロ気孔骨格部は前記マクロ気孔骨格部の表面に設けられ、前記マクロ気孔骨格部と前記ミクロ気孔骨格部とは同一のエンジニアリングプラスチックにより形成され、マクロ気孔骨格部は単一材料からなることを特徴とする生体インプラント。
