That hemocompatible materials have the last the one and tight synthetic substrate wherein such as ox of the animal tissue such as animal of a biology, pericardium is attached, and passes through the substrate for spreading and forming material in a kind of solvent. Substrate is made of elastomer, such as polyurethane or silicone elastomer. Tissue uses monoethylene glycol, such as polyethylene glycol to be treated for several days, once it is attached to substrate. One independent claims further include a kind of a kind of method for manufacturing hemocompatible materials.Ifølge oppfinnelsen som omfatter et blodforenelige materialet et sterkt og lekkasjetett syntetisk substrat, til hvilket et biologisk vev adhereres i kraft av bestanddelsubstansen av det angitte substrat dispergert i et løsningsmiddel.
