The present invention is directed to at least partially degradable implants and methods for the manufacture there of which use powder molding techniques. Specifically, the methods include the steps of providing a suspension comprising a plurality of first particles of at least one organic polymer; a plurality of second particles of at least one metal-based material which is at least partially biodegradable in-vivo; and at least one solvent; wherein the first and second particles are substantially insoluble in the solvent; molding the suspension to form a green body comprising the first particles embedded in a matrix of compressed second particles; removing the first particles from the green body by thermally induced decomposition and/or evaporation; and sintering the green body to form the implant; wherein the step of removing the first particles is performed during sintering.
La présente invention concerne des implants au moins partiellement dégradables ainsi que des procédés de fabrication de ceux-ci utilisant des techniques de moulage de poudre. De manière plus spécifique, les procédés comprennent les étapes consistant à fournir une suspension comprenant une pluralité de premières particules d'au moins un polymère organique; une pluralité de secondes particules d'au moins un matériau à base de métal qui est au moins partiellement biodégradable in vivo; et au moins un solvant; dans laquelle les premières et secondes particules sont sensiblement insolubles dans le solvant; mouler la suspension pour former un corps vert comprenant les premières particules scellées dans une matrice de secondes particules compressées; retirer les premières particules du corps vert au moyen d'une décomposition et/ou évaporation induite thermiquement; et fritter le corps vert pour former l'implant. L'étape de retrait des premières particules est réalisée pendant le frittage.
