Implant with a base body made of a biocorrodible alloy and a biocorrosion-reducing coating

摘要

the invention relates to an implant with a basic body, in whole or in part from a biokorrodierbaren metallic material. at least the biokorrodierbaren metallic material from the existing parts of the grundku00f6rpers are covered with a korrosionshemmenden coating.the coating comprises a haftvermittlerschicht from a first biodegradierbaren polymer material and on the haftvermittlerschicht applied protective layer made of a second biodegradierbaren polymer material. the implant is characterized by the fact that(i) the first biodegradierbare polymer material haftvermittlerschicht a poly (d, l - lactid) (pdlla) with a degree of polymerisation in the range of 5 to 20; and(ii) the second biodegradierbare polymer material layer of a diblockcopolymer (peg / plga) polyethylene glycol (peg) and poly (d, l - lactid (glycolide) (plga).
