摘要:
The present invention relates to a coated medical implant wherein the coating comprises an amorphous Me oxide layer or an (Al, Me) oxide layer deposited by physical vapor deposition, and wherein Me can be one or more of the elements of Ti, Si, Cr, Hf, Zr, Ta or Nb. The PVD layer does not have any bioactive/osseointegrating properties at temperatures below 45° C. This makes it easy to remove the implant after it has being inserted in an animal or human body, e.g. when used for fixating fractures. The coating may further comprise a calcium phosphate layer, preferably a hydroxyapatite layer, which is grown on the PVD layer using a biomimetic process. The coating may be loaded with a releasable agent such as a pharmaceutical agent, an ion or a bio molecule. The present invention also relates to a method for forming the coated medical implant.
