Element provided with a fibrin layer, preparation and use thereof
First Claim
1. An element comprising:
- a support having a thickness and a face;
the face having at least two pores extending through the entire support thickness and spaced from one another to define a node spacing, one of the at least two pores having a diameter from about 10 μ
m to about 20 μ
m, the other pore having a diameter greater than about 20 μ
m; and
a substantially fibrinogen-free non-hydrolyzed fibrin network in direct contact with the face and extending into each pore a distance from about 2 μ
m to about 20 μ
m.

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 μm, 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.
