Abstract
An implant having a surface coating of growth factors for animal or human cells, wherein the growth factors are covalently bonded to bonding-active groups of a polymer on the base body of the implant.
Claims15
An implant comprising:
- a rigid, implantable base body;
- a polymer layer anchored to the surface of said base body, said polymer layer having bonding-active groups at least on a polymer surface thereof remote from said base body
- polyclonal antibodies bonded to said polymer surface by said bonding-active groups;
- and
- growth factors for animal cells including bone substance-inducing proteins bound to said polyclonal antibodies, wherein said polyclonal antibodies are receptors for said bone substance-inducing proteins.

A bone implant comprising:
- a rigid, implantable base body;
- a polymer layer anchored to the surface of said base body, said polymer layer having bonding-active groups on a polymer surface remote from said base body;
- and
- polyclonal antibodies bonded to said polymer surface by said bonding-active groups, said polyclonal antibodies being receptor for bone substance-inducing proteins;
- wherein, upon implantation of said bone implant in an animal or human body, said polyclonal antibodies absorb bone substance-inducing proteins from the environment in the body.
