The object of the invention is to provide a method for producing shaped bodies made from crosslinked gelatine that can be used as substrates for tissue implants and have individually adjustable decomposition periods. The method comprises the following steps: (a) preparation of an aqueous gelatine solution; (b) partial crosslinking of the dissloved gelatine; (c) production of a shaped body using the gelatine solution containing the partially crosslinked gelatine; and (d) crosslinking the gelatine contained in the shaped body.
L'invention vise à mettre au point un procédé pour produire des corps moulés à base de gélatine réticulée, aptes à être utilisés comme matériau support pour des implants tissulaires et présentant une période de décomposition ajustable individuellement. A cet effet, il est prévu que ledit procédé comprenne les étapes suivantes: a) produire une solution de gélatine aqueuse; b) réticuler partiellement la gélatine dissoute; c) produire un corps moulé, à partir de la solution de gélatine avec la gélatine partiellement réticulée; et d) réticuler la gélatine contenue dans le corps moulé.
