Ralf Guillaume Heijkants 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 for the preparation of new segmented polyurethanes with high tear and tensile strengths and method for making porous scaffolds
    Publication number: 20070037954
    Abstract: The invention presents a new method to prepare biomedical polyurethanes with high tensile and tear strengths. Such polyurethanes are especially interesting for making foams thereof, e.g. as meniscus implants. A new method, applicable to the biomedical polyurethanes, has been found to make such foams, that can be used as scaffolds. This method is based on salt leaching and phase separation.
    Type: Application
    Filed: October 19, 2006
