Patents by Inventor Dietmar Werner Hutmacher

Dietmar Werner Hutmacher 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).

  • Publication number: 20210030528
    Abstract: The present invention relates to the field of implants. In particular, the present invention relates to an implant for tissue reconstruction which comprises a scaffold structure that includes a void system for the generation of prevascularized connective tissue with void spaces for cell and/or tissue transplantation. Moreover, the present invention relates to a method of manufacturing such an implant, to the internal architecture of such an implant, to a removal tool for mechanical removal of space-occupying structures from such an implant, to a kit comprising such an implant and such a removal tool, to a removal device for the removal of superparamagnetic or ferromagnetic space-occupying structures from such an implant, as well as to a guiding device for providing feedback to a surgeon during the procedure of introducing transplantation cells into the void spaces generated upon removal of space-occupying structures from such an implant.

  • Patent number: 8071007
    Abstract: The invention relates to the use of Fused Deposition Modeling to construct three-dimensional (3D) bioresorbable scaffolds from bioresorbable polymers such as polycaprolactone (PCL), or from composites of bioresorbable polymers and ceramics, such as polycaprolactone/hydroxyapatite (PCL/HA). Incorporation of a bioresorbable ceramic to produce a hybrid/composite material support provides the desired degradation and resorption kinetics. Such a composite material improves the biocompatibility and hard tissue integration and allows for increased initial flash spread of serum proteins. The basic resorption products of the composite also avoids the formation of an unfavorable environment for hard tissue cells due to a decreased pH. The scaffolds have applications in tissue engineering, e.g., in tissue engineering bone and cartilage.
