  • Implant-based repair of osteochondral defects
    Patent number: 10624987
    Abstract: The present invention is directed to a unique technology for preparing a growth-factor free, cylindrical, hydrogel implant that has multiple (three or more) longitudinal hydrogel zones with varying chemical and physical properties. The implant may be wholly made of hydrogels or the hydrogels may be associated with cells, such as mesenchymal stem cells (MSCs).
    Type: Grant
    Filed: September 3, 2016
    Date of Patent: April 21, 2020
    Assignee: The Texas A&M University System
    Inventors: Melissa A. Grunlan, Mariah S. Hahn, William B. Saunders

  • Shape memory polymer scaffolds for tissue defects
    Patent number: 9925297
    Abstract: A method of making a shape memory polymer (SMP) tissue scaffold includes forming a salt template and adding a macromer solution to the salt template. The macromer solution may include a photoinitiator solution. The method includes drying the SMP scaffold and leaching salt from the SMP scaffold. A coating is then applied to the SMP scaffold. The coating may be applied either before or after heating the SMP scaffold.
