Abstract
A porous implant matrix consists mainly of a mixture of polymers which are differently rapidly degradable, wherein nominal resorption times of two of the components of the mixture, each accounting for at least 10% of the mixture, differ by a factor of at least 5. The porous implant matrix is manufactured from a mixture of the at least two differently rapidly degradable polymers, wherein particles of both polymers are mixed with particles of a water-soluble solid and a solvent for one of the polymers, and after evaporating the solvent is optionally compacted, and the solid is removed by watering.
Claims13
A porous implant matrix, mainly comprising a mixture of differently rapidly resorbable polymers, wherein nominal resorption rates of two of the mixture polymers, each accounting for at least 10% of the mixture, differ by a factor of at least 5, wherein the porous matrix comprises a surface hydrophilically coated with poly(acrylic acid), PAA, wherein a PAA layer thickness initially applied under the influence of a plasma is less than a PAA layer thickness subsequently applied without action of the plasma, wherein the porous matrix has a connective porosity of at least 80%.
