  • Patent number: 8637230
    Abstract: The current invention provides a new organ preservation solution, suitable for machine perfusion, for maintaining viability of organs, parts of organs and tissues. This solution has been designed to overcome a number of problems associated with hypothermic machine perfusion of donor organs, in particular organs obtained from non-heart-beating donors. The solution prevents or minimizes the adverse affects caused by ischemia, hypoxia, energy and nutrient depletion, acidification, hypothermia and reperfusion injury. The preservation solutions according to the current invention are superior to current state of the art preservation solutions, in particular for preservation and perfusion of organs obtained from non-heart-bearing donors, by supplying increased concentrations and an optimized balance of amino acids, vitamins, anti-oxidants, high molecular weight additives and enhanced buffering capacity.

  • Patent number: 8623591
    Abstract: Methods of isolating cellular products, such as pancreatic islets, may be used in diabetes research and therapeutic transplantation. The methods may involve providing a tissue having desired cells that are less prone to destructive freezing and undesired cells that are more prone to destructive freezing, or pre-treating a tissue to have such characteristics. The methods may involve freezing the tissue, disrupting the tissue, warming the tissue, and separating the desired cells from undesired cellular material to obtain the cellular product. The methods may thereby provide an enzyme-free or reduced-enzyme method of isolating a cellular product that is more consistent, reliable and less toxic than conventional methods. The methods may also yield an optimum quantity of cellular product that retain sufficient functional integrity to be useful as a transplantation resource.

  • Patent number: 8574826
    Abstract: The invention provides methodologies and apparatus for producing a cellular soft-tissue implants, both in small quantities and in commercializable quantities. Such soft-tissue implants include vascular graft substitutes. An acellular graft is produced by subjecting the tissue sample to an induced pressure mediated flow of an extracting solution, followed by inducing a pressure mediated flow of a treating solution, then washing the treated tissue to produce the acellular graft. The acellular grafts produced are uniform and nonimmunogenic. The inventive method allows for the production of multiple decellularized soft tissue implants, where processing time is significantly less than prior art processes and the number of implants produced per day is increased over prior art processes. In clinical use, the decellularized grafts produced exhibit significantly improved in long-term durability and function.
