    • This invention provides a method of inhibiting viable cells transplanted into a subject from being destroyed by the subject's immune system which comprises: a) containing the viable cells, or tissue comprising the viable cells, prior to transplantation within a device comprising a semipermeable membrane; and b) treating the subject with a substance which inhibits an immune system costimulation event in an amount effective to inhibit the subject's immune sytem from responding to said contained cells or tissue. In one embodiment, the substance which inhibits an immune system costimulation event is CTLA4. Also provided by this invention is a method of treating diabetes in a subject which comprises: a) containing viable insulin-producing cells, or tissue comprising such cells, within a device comprising a semipermeable membrane; b) transplanting an effective amount of such contained viable insulin-producing cells into the subject; and c) treating the subject with an effective amount of a substance which inhibits an immune system costimulation event.

    • A hybrid procoagulant factor VIII is produced by isolation and recombination of human and other non-human mammalian factor VIII subunits or domains, or by genetic engineering of the human and animal factor VIII genes. Subunits or domains of factor VIII that have been purified from human or animal plasma are isolated, and hybrid human/animal factor VIII is produced by (1) mixing either animal heavy chain subunits with human light chain subunits or by mixing human heavy chain subunits with animal light chain subunits, thereby producing human light chain/animal heavy chain and human heavy chain/animal light chain hybrid molecules; or by (2) mixing one or more domains of one species with one or more domains of the other species. These hybrid molecules are isolated by ion exchange chromatography. Alternatively, recombinant DNA methods are used to change elements of animal factor VIII or human factor VIII to the corresponding elements of human factor VIII or animal factor VIII, respectively, to produce hybrid human/animal factor VIII.

    • In accordance with the present invention, a composition and method is provided for preserving organs and tissue for transplantation. More particularly, the present invention relates to a method for preserving organs and tissues by perfusing the organ or tissue with a perfusion medium containing an effective amount of a polyoxypropylene/polyoxyethylene surface-active copolymer. The surface-active copolymer may be an ethylene oxide-propylene oxide condensation product with the following general formula (I): HO(C2H4O)b(C3H6O)a(C2H4O)bH, wherein a is an integer such that the hydrophobe represented by (C3H6O) has molecular weight of approximately 950 to 4000 daltons, preferably approximately 1200 to 3500 daltons, and b is an integer such that the hydrophile portion represented by (C2H4O) constitutes approximately 50 % to 90 % by weight of the compound.

    • This invention relates to a self-expanding intraluminal composite prothesis (10) comprised of a rigid reinforcing component (8) and sealing component (12). The prosthesis may be fabricated as either a straight or bifurcated tubular structure and is applicable to the treatment of any bodily passage including, but not limited to, vascular applications, e.g., aneurysms, arteriovenous fistulas, as well as stenotic regions of the peripheral circulation which have been percutaneously dilated but are at high risk for restenosis. The major attributes of this prosthesis can include the use of a unique multilayered biaxial braid which thereby creates a homogeneously blended composite with isotropic deformation and expansion characteristics and an associated high contraction ratio. The use of multiple layers allows for the fabrication of a device of varied porosity while retaining adequate tensile or mechanical wall strength.
