Diana Hendricks 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).

  • Calcium phosphate/atelopeptide collagen compositions for bone repair
    Patent number: 5425770
    Abstract: Processes for the preparation of compositions used in conductive bone repair are disclosed. The compositions contain a mixture consisting essentially of either a calcium phosphate particulate mineral component or particulate hydroxyapatite in admixture with atelopeptide reconstituted fibrillar collagen. The method is comprised of mixing a dispersion of the collagen and mineral, the latter which is present in dry particulate form, followed by molding and drying the composition in a mold to obtain a dried composition.
    Type: Grant
    Filed: July 30, 1993
    Date of Patent: June 20, 1995
    Assignee: Collagen Corporation
    Inventors: Karl A. Piez, Bruce B. Pharriss, George H. Chu, Thomas L. Smestad, Diana Hendricks
  • Xenogeneic collagen/mineral preparations in bone repair
    Patent number: 5246457
    Abstract: A composition for use in bone repair, in particular, in only procedures, which comprises calcium phosphate mineral particles in admixture with atelopeptide reconstituted fibrillar collagen preparations is disclosed. This composition is non-immunogenic and encourages the fusion of host bone with new bone growth through the implant. Additional processes for curing the implant to improve its compressive strength include heat curing, maturation, and cross-linking.
    Type: Grant
    Filed: December 17, 1990
    Date of Patent: September 21, 1993
    Assignee: Collagen Corporation

  • Collagen wound healing matrices and process for their production
    Patent number: 5219576
    Abstract: Collagen implants that are useful as wound healing matrices are characterized by being formed of collagen fibrils that are not chemically cross-linked, and having a bulk density of 0.01 to 0.3 g/cm.sup.3 and a pore population in which at least about 80% of the pores have an average pore size of 35 to 250 microns. The implants are capable of promoting connective tissue deposition, angiogenesis, reepithelialization, and fibroplasia. The wound healing matrix also serves as an effective sustained delivery system for bioactive agents.

  • Method of making molds with xenogeneic collagen/mineral preparations for bone repair
    Patent number: 4992226
    Abstract: A process for coating the pores of a mineral matrix with collagen by pumping collagen through the molded matrix is disclosed. The resulting coated matrix can be used as a prosthesis in bone repair.

  • Xenogeneic collagen/mineral preparations in bone repair
    Patent number: 4795467
    Abstract: A composition for use in bone repair, in particular, in onlay procedures, which comprises calcium phosphate mineral particles in admixture with atelopeptide reconstituted fibrillar collagen preparations is disclosed. This composition is non-immunogenic and encourages the fusion of host bone with new bone growth through the implant. Additional processes for curing the implant to improve its compressive strength include heat curing, maturation, and cross-linking.
