A coated prosthetic implant and a method of forming a continuous coating of highly crystalline polymer over a prosthetic implant by means of passing particles of polymer through a high temperature plasma and subsequently depositing the molten particles over the implant surface. This invention is especially useful for coating polymer composite implants, such as a femoral insert for a hip joint prosthesis, with a coating of poly (aryl-ether-ketone).

Prosthetic implants with a highly crystalline coating

The invention provides biocompatible, corrosion-resistant prostheses and methods for producing these. A coating comprising a bismaleimide-triazine resin, a biocompatible plasticizer and optionally a thickener is applied to a prosthesis substrate and the resin is cured to provide a tightly adherent, biocompatible, corrosion-resistant coating. Radio-opaque materials, such as barium sulfate, may be included in the coating as well as bone ingrowth materials such as hydroxyapatite.
