Patents by Inventor T. R. Gowrishankar

T. R. Gowrishankar 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).

  • Localized molecular and ionic transport to and from tissues
    Patent number: 6706032
    Abstract: The present invention relates to methods and devices used for the formation of microconduits in a tissue. The term “microconduit” refers to a small opening, channel, or hole into, or through, a tissue, that allows transfer of materials by liquid flow, and by electrophoresis, the microconduit being formed upon impact of a plurality of accelerated microparticles with the surface of the tissue. A method is described for forming at least one microconduit in tissue including the steps of: accelerating a plurality of microparticles to a velocity that causes the microparticles to penetrate a region of tissue surface upon impingement of the microparticles on the tissue surface; and directing the microparticle towards the region of tissue surface, thereby causing the microparticles to penetrate the tissue and form a microconduit in the tissue. According to an embodiment, microparticles are accelerated by being hit with a moving, solid surface.
