Title (EN) ABSORBABLE MATERIAL FOR FIXATION OF TISSUES
(FR) MATIERE ABSORBABLE POUR LA FIXATION DE TISSUS
Abstract:
(EN) This invention describes self-reinforced, absorbable materials and devices or their parts or components for surgical fixation of damaged and/or operated tissues, which materials, devices or their parts or components comprise: (1) matrix of an absorbable polymer or copolymer or of a polymer mixture, (2) reinforcement elements or structures constructed of them which are at least partially embedded in matrix and which reinforcement elements have the same chemical element percentual composition as matrix and (3) coating layer which covers a substantial part of the surface of the matrix-reinforcement element system and which coating layer has the same chemical element percentual composition as matrix (1) and reinforcement elements (2) have. The materials of this invention have better mechanical strength properties than the known absorbable materials have. Therefore the materials of this invention can be applied widely in surgical treatment to fixation of tissues or parts of them.
(FR) La présente invention décrit des matières absorbables auto-renforcées et des dispositifs ou leurs parties ou composants servant à la fixation chirurgicale de tissus endommagés et/ou opérés. Ces matières, dispositifs ou leurs parties ou composants comprennent: (1) une matrice d'un polymère ou d'un copolymère absorbable ou d'un mélange polymère; (2) des éléments de renforcement ou des structures construites à partir de ces éléments, qui sont au moins partiellement incorporés dans la matrice et qui ont la même composition en pourcentage d'éléments chimiques que la matrice; et (3) une couche d'enduction qui recouvre une partie substantielle de la surface du système des éléments de renforcement de la matrice et qui a la même composition en pourcentage d'éléments chimiques que la matrice (1) et que les éléments de renforcement (2). Lesdites matières présentent des propriétés de résistance mécanique meilleures que les matières absorbables connues. Ces matières peuvent par conséquent être largement appliquées dans un traitement chirurgical pour la fixation de tissus ou de parties de tissus.
