Porous coating for orthopedic implant utilizing porous, shape memory materials
A porous coating for a medical implant, wherein the porous coating comprises a porous, shape memory material.
1. A method for providing therapy to a patient, the method comprising:
providing a medical implant comprising a static body and a dynamic porous coating secured to a surface of the static body, wherein the dynamic porous coating comprises a porous structure formed of a shape memory material, wherein the porous structure comprises a regular repeating pattern, and further wherein the regular repeating pattern comprises a honeycomb cellular structure; and
inserting the medical implant into the patient so that the dynamic porous coating applies an outward force against adjacent bone so as to create an interference fit between the medical implant and the adjacent bone.
2. A method according to claim 1 wherein the outward force is created by the superelasticity of the shape memory material.
3. A method according to claim 1 wherein the outward force is created by the shape memory effect of the shape memory material.
4. A method according to claim 1 wherein the therapy provided by the outward force applied by the dynamic porous coating is bone remodeling.
5. A method according to claim 1 wherein the static body is constructed from a material comprising one from the group consisting of cobalt-chrome alloys and titanium alloys.
