The present invention provides a porous structure of fibrin or fibrinogen material. The structure in its substantially dry form, having a compression strain of less than 8 %, and a creep modulus higher than 1.5 x 10<6> Pa. The compression strain and creep modulus being measured for a sample having a diameter of 5 mm on which a compression of 2500 milli Newtons is exerted with a compression ramp of 500 milli Newtons per minute, after a compression release step following an initial compression of 2500 milli Newtons with a compression ramp of 500 milli Newtons per minute. After hydration, the structure has a porosity wherein at least 50 % by volume of the total porosity is formed by channels with an open cross section of more than 500 mu m<2>. |
