Patent number: 8906884Abstract: The present invention refers to use of dextran sulfate, or a pharmaceutically acceptable derivate thereof, for manufacturing of a medicament for treatment of Instant Blood-Mediated Inflammatory Reaction (IBMIR). In addition, the invention refers to the use of dextran sulfate, or a pharmaceutically acceptable derivate thereof, for manufacturing of a medicament for treatment of morphological disruption of cell transplants and graft-rejection of cell transplants caused by IBMIR. The invention may be applied to patients suffering from type I diabetes, in which porcine islets of Langerhans are transplanted in their portal vein. Administration of dextran sulfate according to the invention inhibits and prevents rejection and destruction of the transplanted islets and makes normoglycemia in the patients possible.Type: GrantFiled: January 11, 2010Date of Patent: December 9, 2014Assignee: TX Medic ABInventors: Bo Nilsson, Olle Korsgren

Patent number: 7955613Abstract: A bioartificial implant comprises a semipermeable barrier designed from one side to allow diffusion or prevent diffusion of predetermined substances/materials/molecules/cells/cell lines produced in the human body to the other opposite side of the barrier, and from said other opposite side to allow diffusion or prevent diffusion of predetermined substances which are the same as or different from the first mentioned substances/materials/molecules/cells/cell lines. The semipermeable barrier has a surface coating at least on said one side a bioactive metal, such as titanium, which surface coating is permeable to allow said diffusions. In a method for reducing the risk of formation/growth of connective tissue in connection with an implant which comprises a semipermeable barrier, the barrier is provided at least on one side with a permeable coating of bioactive metal. An example of the use of the implant is bioartificial pancreas.Type: GrantFiled: October 4, 2004Date of Patent: June 7, 2011Assignee: Tikomed ABInventors: Adam Bruce, Lars Bruce, Bo Nilsson, Olle Korsgren
