  • Patent number: 9138521
    Abstract: An ultrafiltration device and method for the removal of excess fluid in hypervolemic patients and/or removal of toxins in the blood including for patients suffering from either renal or cardiovascular disease is disclosed. An embodiment of the device includes a housing containing multiple large bore hollow fiber membranes which are connected to the patient's vascular system via a connecting element comprising bifurcated fluid pathway elements to physiologically channel the blood flow either to or from each hollow fiber membrane of the device, a channel to direct the fluid removed by the device to a suitable collection container or the patient's bladder, and controls that control excessive removal of the water from the patient. Devices can be either worn extracorporeally or surgically implanted in order to allow for continuous fluid removal with ambulatory freedom.
    Type: Grant

  • Patent number: 5002661
    Abstract: A device which serves as an artificial pancreas comprises a hollow fiber having an inner diameter of about 5 mm which is surrounded by islets of Langerhans enclosed in a housing. The islets are suspended in a semi-solid matrix which ensures desired distribution of the cells about the hollow fiber. The hollow fiber and suspended islets are enclosed in a housing which further aids the desired distribution of islets about the hollow fiber. The hollow fiber has a porosity which selectively allows passage of substances having a molecular weight of less than about 100,000 Daltons. The semi-solid matrix in which the islets are embedded and suspended is formed of an appropriate supporting material such as alginate or agar.

  • Patent number: 4212742
    Abstract: A filtration device for effecting separation of a blood cell-free liquid filtrate from a blood cell-containing liquid suspension in continuous laminar flow therethrough, employing a microporous filtration membrane. The filtration flow channels along the surface of the upstream side of the membrane wall are provided with a width across the membrane wall surface which gradually and uniformly increases from the inlet end to the outlet end of the flow channel, whereby the membrane wall shear rate of the suspension in laminar flow through the flow channel will gradually and uniformly vary along the length of the flow channel from a maximum value at its inlet end to a minimum value at its outlet end. Such variation in shear rate corresponds with the variation in the transmembrane pressure conditions along the length of the flow channel so as to enable better control of the filtration operating conditions to insure optimal filtration rates per area of membrane without damage to the blood cells.
