  • Patent number: 9770538
    Abstract: Skin regeneration or grafting is promoted utilizing a structure including a multi-layer sheet of collagen membrane material which includes a purified collagen barrier sheet material derived from natural collagen-containing tissue, the barrier sheet material including a barrier layer with an outer smooth barrier face and a fibrous face opposite the smooth barrier face. The structure further includes a matrix layer of collagen sponge material adjacent to the fibrous face. The matrix layer of collagen sponge material is resorbed by a body of a subject at a substantially faster rate than the barrier sheet material.

  • Patent number: 9028866
    Abstract: It now has been found that oral administration of pharmaceutical agents, including N-methylol transfer agents such as Taurolidine may be used to provide efficacious blood plasma concentration of the agents for treatment of diseases by providing release of the active agent into the duodenum or jejunum of a patient and/or at a pH of about 5.4 to about 6.5. Embodiments of the invention therefore provide oral dosage forms, compositions and methods for administration of pharmaceutical agents to the duodenum or jejunum of a patient, and/or which release at a pH of about 5.4 to about 6.5.

  • Patent number: 8084428
    Abstract: A method of repairing a meniscal tear of a subject includes providing a sheet of collagen membrane material having on one side thereof a smooth barrier face which inhibits cell adhesion thereon and inhibits passage of cells therethrough. The sheet has a fibrous face opposite the smooth barrier face, the fibrous face allowing cell growth thereon. The collagen is predominantly collagen I. The sheet of collagen membrane material is fixed over a meniscal tear so that the fibrous face is oriented toward the meniscal tear.
