Patent number: 8246620Abstract: An abrading device including an advanced burr and appliqué for a burr and a new process for making cutting tools for fine material removal applications such as in bone and tissue surgeries. An appliqué sheet is first engineered by CAD with an abrading surface having cutting facets. The appliqué is attached to a surface of a tool blank and then metallurgically bonded and coated by the BRAZOL® or Co—P process. The tool blank has a proximal shank attachable to a driver and a distal surface to which the appliqué is affixed. Since each facet is attached to surrounding facets and then strongly bonded to the tool, the facets do not dislodge when used to abrade a surface of an object. The BRAZOL® or Co—P coating imparts excellent wear resistance and lubricity to the cutting facets. This results in excellent operational and material removal characteristics. This approach to making surgical and fine industrial tools offers engineered flexibility in design rather than process dependent designs.Type: GrantFiled: December 17, 2008Date of Patent: August 21, 2012Inventors: Kenneth Holko, Thomas D.

Patent number: 7878988Abstract: A method of measuring healing strength of bone includes a bone fixation plate (14) implanted at the healing area between bone segments (12). The bone fixation plate (14) includes high aspect ratio material with electric current conduction properties responsive to strain. This method causes an induced, or directly applied, electric current to pass through the high aspect ratio material. Analysis of the change in this current by a series of increasing loads placed on the healing body part indicates what level of load produces strain on the bone fixation plate (14). As healing strength increases, evidence of strain on the bone fixation plate (14) occurs at a greater load. Physicians determine thereby the strength of bone healing and safe levels of activity for patients while bone healing progresses.Type: GrantFiled: October 6, 2006Date of Patent: February 1, 2011Inventors: Stephen Thomas Bush, Stephen Francis Bush
