Abstract
Various embodiments of implant systems and related apparatus, and methods of operating the same are described herein. In various embodiments, an implant for interfacing with a bone structure includes a web structure, including a space truss, configured to interface with human bone tissue. The space truss includes two or more planar truss units having a plurality of struts joined at nodes. Implants are coated with, or have struts formed from, a piezoelectric material to enhance bone growth around and through the implant.
Core Innovation
The invention relates to an implant for interfacing with a bone structure that includes a web structure comprising a plurality of struts joined at nodes. The web structure is configured to interface with human bone tissue, and one or more of the plurality of struts is provided with a coating of a piezoelectric hydroxyapatite composition placed on one or more of the struts.
The piezoelectric hydroxyapatite composition includes a hydroxyapatite and a piezoelectric ceramic material, where the hydroxyapatite is doped with a conductive dopant. The conductive dopant comprises at least one of gold, silver, cesium, zinc, or silicon.
In certain embodiments, the web structure is a space truss comprising two or more planar truss units. The struts may be configured by predetermined strut geometry and physical properties so that contact with bone induces stress in the piezoelectric coating sufficient to generate a piezoelectric effect.
Claims Coverage
The partial claims provided include three independent claims. Each independent claim is directed to an implant or a repair method and centers on a piezoelectric hydroxyapatite composition with a conductive-doped hydroxyapatite and a web structure of struts joined at nodes.
Piezoelectric doped hydroxyapatite coating on bone-contacting web struts
An implant for interfacing with a bone structure including a web structure comprising a plurality of struts joined at nodes configured to interface with human bone tissue; and a coating of a piezoelectric hydroxyapatite composition placed on one or more of the plurality of struts, the piezoelectric hydroxyapatite composition including a hydroxyapatite and a piezoelectric ceramic material, wherein the hydroxyapatite is doped with a conductive dopant.
Repairing a bone structure by coupling a piezoelectric hydroxyapatite web implant
A method of repairing a bone structure comprising obtaining an implant with a web structure comprising a plurality of struts joined at nodes configured to interface with human bone tissue, wherein one or more struts are coated with a piezoelectric hydroxyapatite composition including a hydroxyapatite and a piezoelectric ceramic material, wherein the hydroxyapatite is doped with a conductive dopant; and coupling the implant to the bone structure.
Space truss web with piezoelectric hydroxyapatite struts for bone interfacing
An implant for interfacing with a bone structure including a web structure comprising a plurality of struts joined at nodes wherein the web structure comprises a space truss comprising two or more planar truss units and is configured to interface with human bone tissue; wherein one or more of the plurality of struts are composed of a piezoelectric hydroxyapatite composition including a hydroxyapatite and a piezoelectric ceramic material, wherein the hydroxyapatite is doped with a conductive dopant.
