Oliva V. LaChance 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).

  • Method of making enhanced cell growth surface
    Patent number: 8497126
    Abstract: A method of producing an improved cell growth surface and cell attachment surface. According to the present invention, a polymer article is molded at temperature in excess of 550° F. at the injection tip. After allowing the part to cool, a stream of plasma comprised of activated gaseous species generated by a microwave source is imparted on the article. This stream is directed at the surface of a polymer substrate in a controlled fashion such that the surface is imparted with attributes for cell adhesion superior to those of untreated polymer or polymer treated by other methods.
    Type: Grant
    Filed: June 29, 2007
    Date of Patent: July 30, 2013
    Assignee: Corning Incorporated
    Inventors: Marie D. Bryhan, Paul E. Gagnon, Jr., Zhong-he Shen, Oliva V. LaChance, Hongming Wang
  • Cell growth surface on a polymeric substrate
    Patent number: 7579179
    Abstract: A product exhibiting an improved cell growth surface and cell attachment. According to the present invention, a stream of plasma is comprised of activated gaseous species generated by a microwave source. This stream is directed at the surface of a polymer substrate in a controlled fashion such that the surface is imparted with attributes for cell adhesion far superior to that of untreated polymer or polymer treated by other methods.
