  • Patent number: 10864297
    Abstract: A method of manufacturing an implant for use in a surgical procedure, a corresponding implant and the use thereof during the incorporation of a substance is presented. Specifically anodized and blasted titanium implant substrates are provided with a hydroxyapatite (HA) coating for incorporating for example a therapeutic agent. In particular, an anodizing procedure by an electrolytic process in an alkaline liquid is carried out. Moreover, blasting of the anodized titanium implant substrate is carried out by the presented method. The HA coating can be in the range of 1 to 5 ?m, particularly in the range of 1 to 3 ?m. A local delivery of the active pharmaceutical ingredient is achieved by the implant of the present invention. Moreover, the implant allows for the removal of the implant without damaging surrounding tissue or a bone. Moreover, the HA coating is provided to the substrate such that enhanced fixation as measured by pull-out force is achieved whilst having a relatively low removal torque.

  • Patent number: 9662425
    Abstract: A method for loading a hydroxyapatite coated implant with a therapeutic agent including the steps of providing an implant and applying a hydroxyapatite coating on a surface of the implant. The hydroxyapatite coated implant is contacted with a solution including the therapeutic agent. The hydroxyapatite coated implant and solution is heated to temperature of about 60° C. to about 100° C. Pressure is applied to the hydroxyapatite coated implant and solution from about 2 bar to about 10 bar, to load the hydroxyapatite coated implant with the therapeutic agent. An implant made according to the method has sustained therapeutic agent delivery and includes a base and a biomimetic hydroxyapatite coating disposed on a surface thereof.
