Tobin N. Gerhart 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: 5364839
    Abstract: Osteoinductive pharmaceutical formulations comprising antifibrinolytic agents such as epsilon amino acid caproic acid or other lysine analogues or serine protease inhibitors and cartilage and/or bone inductive proteins are disclosed. These formulations are useful in the treatment of cartilage and/or bone defects.
    Type: Grant
    Filed: June 18, 1990
    Date of Patent: November 15, 1994
    Assignee: Genetics Institute, Inc.
    Inventors: Tobin N. Gerhart, Elizabeth A. Wang, Mary J. Kriz
  • Patent number: 5286763
    Abstract: Bioerodible polymers which degrade completely into nontoxic residues over a clinically useful period of time, including polyanhydrides, polyorthoesters, polyglycolic acid, polylactic acid, and copolymers thereof, are used for the delivery of bioactive agents, including antibiotics, chemotherapeutic agents, inhibitors of angiogenesis, and simulators of bone growth, directly into bone.
    Type: Grant
    Filed: June 30, 1992
    Date of Patent: February 15, 1994
    Assignee: Massachusetts Institute of Technology
    Inventors: Tobin N. Gerhart, Cato T. Laurencin, Abraham J. Domb, Robert S. Langer, Wilson C. Hayes
  • Patent number: 5085861
    Abstract: An improved bone cement is comprised of a particulate biocompatible calcium phosphate ceramic and particulate resorbable calcium salt dispersed in a cross-linked biodegradable polyester matrix. The polymer/salt-particle composite exhibits good biomechanical strength/modulus characteristics with surgically acceptable cure times. When used for sustained release of biologically active agents in a physiological environment, controlled release of biological agents that are mixed into the composite can be achieved as the cement biodegrades. When used for bone/implant fixation, or as a filler or cement for bone repair, gradual biodegradation of the cement composite permits, under suitable circumstances, evantual replacement of the cement with developing bone tissue.
