Abstract
The invention relates to an antimicrobial material for implanting in bones and for coating or producing an implant or an implantable medical device, whereby particles formed from an antimicrobial material are remotely dispersed inside a matrix material that forms a matrix when hardened. In order to improve the compatibility of the antimicrobial material, the invention provides that the metal is formed from aggregates of primary particles having an average particle size ranging from 10 to 100 nm.
Claims34
An antimicrobial implant material for implanting in bones, the material comprising:
- aggregates formed from an anti-microbial metal;
- and
- a polymer matrix material which forms a matrix in the cured state,
- wherein the aggregates are discrete and finely dispersed in said matrix material, wherein the aggregates are highly porous and are formed of primary particles connected together by necks, wherein the primary particles have an average particle size between 10 and 100 nm, and wherein the metal is not more than 5.0% by weight based on the weight of the polymer matrix material.
