Abstract: Disclosed are compositions and methods for the preservation, storage, and transport of living biological tissues, organs, and populations of isolated cells. In particular, the disclosed compositions and processes permit mammalian cells, tissues, and organs to be harvested from suitable donor animals, stored for prolonged periods, and transported to the site of recipient implantation, all without significant loss of cell viability, biological activity, and/or tissue integrity.

Abstract: The present invention provides an air flow control device that includes at least one inlet, and a primary flow path associated with a primary outlet, and a secondary flow path associated with a secondary outlet. The air flow device also includes at least one primary valve associated with the primary flow path, said at least one primary valve being adapted to control the flow rate of air through said primary flow path.

Abstract: A biodegradable medicament delivery system comprising a multi-layered calcium-sulfate based drug delivery vehicle. The vehicle comprises a calcium sulfate center or core with the medicament or medicaments, encased in one or more layers of chitosan. The chitosan may be cross-linked with a cross-linking agent. The vehicle may comprise any suitable shape, including, but not limited to, a sphere, bead or pellet. Medicaments include, but are not limited to, antibiotics, anesthetics, growth factors, and proteins. A physician can implant the coated vehicles into the desired site to create a beneficial, localized treatment that produces high local concentrations of medication while reducing the overall serum concentration throughout the body.
