  • Patent number: 9788821
    Abstract: Described are expanded collagenous materials and methods for their preparation and use. Certain expanded collagenous materials can be prepared by treating a first collagenous material with an alkaline substance under conditions effective to expand the first collagenous material, and recovering the expanded material. Expanded materials can exhibit beneficial persistence and tissue generation characteristics when implanted, and can be used in the formation of highly porous medical implant bodies which can be compressed to fractions of their original volume and will thereafter substantially recover their original volume.

  • Patent number: 8454678
    Abstract: Described are preferred prosthetic valve devices including a first extracellular matrix material having a second extracellular matrix material deposited thereon. The preferred materials are made by culturing cells in contact with an extracellular matrix graft material in a fashion to cause the cells to biosynthesize and deposit extracellular matrix components on the material. The cells are then removed to provide the extracellular matrix composite material. In preferred embodiments, the prosthetic valve devices are configured for use in vascular applications.
