Patrick E. Heam 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).

  • Oriented polymer implantable device and process for making same
    Patent number: 8691136
    Abstract: A device is formed by the process into a bone screw or fastener, wherein the head has a degree of polymer alignment and strength, and wherein the shank has a higher degree of polymer alignment and strength. In practice of the present invention, the polymer slug is pressed into the die cavity by the actuation of ram press, causing the slug to conform to the die cavity. Through this process, the polymer molecular orientation is aligned to different degrees, in different zones of the device.
    Type: Grant
    Filed: May 13, 2008
    Date of Patent: April 8, 2014
    Assignee: Kensey Nash Corporation
    Inventors: Joseph DeMeo, Patrick E. Heam, Robert L. McDade
  • ORIENTED POLYMER IMPLANTABLE DEVICE AND PROCESS FOR MAKING SAME
    Publication number: 20130053850
    Abstract: A device is formed by a discontinuous process into a bone screw, plate, or fastener, wherein the device has a degree of polymer alignment and strength, and upon reheating above glass transition temperature of the polymer, the device remains dimensionally stable, as it maintains its dimensions, strength, and degree of polymer orientation. In practice of the present invention, the polymer slug is pressed into the die cavity by the actuation of ram press, causing the slug to conform to the die cavity.
