Soundarapandian Santhanakrishnan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10729497
    Abstract: An apparatus and method for laser-assisted machining (LAM) of non-monolithic composite bone material is described. A high intensity focused laser beam conducts bone material removal in extremely short time duration without causing any thermal (necrosis) and mechanical damage to the material surrounding the bone-laser interaction region. A computer associated with the apparatus for machining bone preferably employs a Multiphysics computational modeling approach which takes into account physical phenomena such as heat transfer, fluid flow, convection mixing, and surface tension when determining bone target volume, calculating material properties of the multicomponent and multicomposition composite bone material, determining parameters for the laser-assisted machining based on the material properties, and performing the laser-assisted cutting/shaping/machining of bone.
    Type: Grant

  • Patent number: 9387041
    Abstract: An apparatus and method for laser-assisted machining (LAM) of bone without raising the temperature of the surrounding bone is discussed. The method of LAM of bone involves determining a target bone needing to be machined an then scanning a high power density laser beam along the bone at a machining rate that produces low-heat affected zones (HAZ) on the target bone. The process and apparatus is advantageous over conventional technologies because it provides a chemically clean, coherent, and monochromatic beam to the region to be machined.
