Patents by Inventor George C. Michaels

George C. Michaels 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).

  • Patent number: 7026026
    Abstract: Balloons for use on medical devices such as catheter balloons are formed from polymer blend products which include a liquid crystal polymer (LCP), a crystallizable thermoplastic polymer, especially thermoplastic polyesters such as PET, and a compatabilizer. The compatabilizer may be an ethylene-maleic anhydride copolymer, an ethylene-methyl acrylate copolymer, an ethylene-methyl acrylate copolymer, an ethylene-methyl acrylate-maleic anhydride terpolymer, an ethylene-methyl-methacrylic acid terpolymer, an acrylic rubber, an ethylene-ethyl acrylate-glycidyl methacrylate terpolymer or a mixture of two or more such polymers.
    Type: Grant
    Filed: December 16, 2002
    Date of Patent: April 11, 2006
    Assignee: Boston Scientific Scimed, Inc.
    Inventors: David A. Ferrera, George C. Michaels, Ralph J. Barry, Lixiao Wang, Jianhua Chen
  • Patent number: 6866649
    Abstract: A balloon for a medical device has a structural layer of a highly crystallized PEN polymer material. The PEN polymer material a polyethylene naphthalate homopolymer or a crystallizable copolyester made up of residues of ethylene glycol, naphthalene dicarboxylic acid (NDC) and at least one member of the group (PA) consisting of terephthalic acid and isophthalic acid. The NDC groups make up about 5% or more of the sum of NDC and PA groups in the copolymer. The balloon is characterized by an ability to withstand a hoop stress of at least 35,000 psi without bursting.
