Abstract:
An element provided with a layer based on fibrin- or fibrinogen-containing material, said element comprising (a) a hydrophobic or substantially hydrophobic support, which has a porous part with a thickness of 0.1 to 5 mm, and whose pores, extending across its thickness have a node spacing of 5 to 100 mu m, one face of said porous part being treated with a compound based on fibrin and/or a fibrinogen-containing material, and (b) a fibrin-based layer covering said treated surface of the support, characterized in that said fibrin-based layer is substantially uniform and homogeneous on said treated surface, and that the fibrin layer and at least the face of the support in contact with the fibrin layer are substantially free of fibrinogen.
Abstract:
Elément présentant une couche à base de fibrine ou de matière contenant du fibrinogène, ledit élément comportant (a) un support hydrophobe ou sensiblement hydrophobe présentant une partie poreuse dont l'épaisseur est comprise entr 0,1 et 5 mm et dont les pores s'étendant au travers de son épaisseur ont un espace internodal compris entre 5 et 100 µm, une face de ladite partie poreuse dudit support étant traitée au moyen d'une composition à base de fibrine et/ou de matière contenant du fibrinogène, et (b) une couche à base de fibrine recouvrant ladite face traitée du support, caractérisé en ce que ladite couche à base de fibrine est sensiblement uniforme et homogène sur ladite face traitée, et en ce que la couche de fibrine et au moins la face du support en contact avec la couche de fibrine sont sensiblement exempts de fibrinogène.
