Patents by Inventor Patrick E. Hearn

Patrick E. Hearn 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).

  • Compressed porous materials suitable for implant
    Patent number: 8445554
    Abstract: A high strength porous polymeric material manufactured by a compression process is disclosed. The material results in a network of interconnected collapsed pores, which forces thin overlapping walls and passages to be created. The network provides permeable access for fluid migration throughout the material. The strength and/or permeability are advantageous for medical devices and implants.
    Type: Grant
    Filed: May 24, 2010
    Date of Patent: May 21, 2013
    Assignee: Kensey Nash Corporation
    Inventors: Timothy A. Ringeisen, Amanda Turner, Joseph DeMeo, Patrick E. Hearn, Robert L. McDade

  • Oriented polymer implantable device and process for making same
    Publication number: 20100191292
    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.

  • Oriented polymer implantable device and process for making same
    Patent number: 7378144
    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.
