Abstract: A panel assembly for being manually mounted on a blood therapy apparatus is characterized by three panels, a center panel configured for manually securing a hemofilter cartridge and opposite side panels, hingedly connected to the center panel. The side panels have generally flat, planar interior surfaces defined by a rim extending around its perimeter. Tubing is secured along and adjacent to the interior panel surfaces, which are also provided with tubing supports having slanted tubing channels for supporting arched pump rotor engaging tubing sections and prevent tubing droop.

Abstract: An extracorporeal blood therapy control unit housing has a first and second manually mounted panels and spring loaded components configured for releasably engaging and tensioning the said panels against a side of said housing. The first and second panels have arch-shaped tubing segments mounted on the interior side of said respective panels. Each of the tubing segments are held in operational engagement with a different peristaltic pump rotor by the panel engaging and tensioning components.

Abstract: A plasmapheresis and/or ultrafiltration membrane comprises elongated hollow fibers each fiber having an interior lumen extending along the fiber length, the fiber wall having a plurality of zones between the inner and outer wall surfaces, each of the zones having a mass density different than the mass density of an adjacent zone. The fiber wall is characterized by having a lower mass density zone at the inner wall surface and a higher mass density zone at the outer wall surface. The fiber is further characterized by having an average elongation breaking force strength of at least about 0.2 lbs. and an average elongation of at least about 45%.

Abstract: An in-vivo plasmapheresis or in-vivo ultrafiltration membrane comprises a plurality of elongated hollow microporous fibers each fiber having an outer wall, an inner wall and an interior lumen extending along the length thereof and defined by an inner wall surface, and wherein the fiber wall structure is a substantially continuous change in mass density from the outer wall to the inner wall and comprises a continuum of voids bounded by solid frames, the fiber wall having an asymmetrical pore size and asymmetrical mass density between said inner wall surface and the outer wall surface with a higher mass density adjacent to the outer wall and a lower mass density adjacent to said inner wall, and characterized by a nitric oxide donor composition capable of producing or releasing nitric oxide or inducing nitric oxide production or release in-vivo with a blood vessel, distributed on or in the fiber wall.
