Patents by Inventor Thomas Cole Waram

Thomas Cole Waram 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).

  • Self adjusting, high strength, screw system
    Patent number: 6860691
    Abstract: A faster system includes a screw or bolt having two interleaved helical threads, which bracket a helicoil. The helicoil expands and torques by various means to maintain hold and purchase between the screw coil combination and the substrate into which the screw and helicoil are inserted even when the substrate recedes a significant distance from the screw and helicoil combination. The fastener system includes means for latching the tilt of the coil so as to minimize the constraining forces and optimize the motion of the helicoil, that results in the screw or bolt being pushed into the substrate.
    Type: Grant
    Filed: November 29, 2002
    Date of Patent: March 1, 2005
    Inventors: John Duncan Unsworth, Thomas Cole Waram
  • Shape memory tubular stent
    Patent number: 6635079
    Abstract: A stent radially expandable from a radially contracted introduction state into a radially expanded position state, in which the final shape of the stent can be controlled by varying the amount and places energy is delivered onto the interior surfaces of the tubes from which the stent is fabricated, and means to seal the opening into the aneurysm, thereby causing the blood therein to clot and preventing the aneurysm from growing or rupturing.
