On April 12, 2016 , the USPTO issued U.S. Patent Number 9,308,307 to Fresenius Medical Care Holdings, Inc., which was successfully prosecuted by Novel IP.

The '307 patent  is directed towards  a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The manifold includes diaphragms adapted to minimize the dead space between the dialysis machine pins and improve responsivity. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface and a heater in thermal communication with the container. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

Independent Claim 1 describes " A disposable manifold having a diaphragm integrated therein and adapted for use in a dialysis machine, said diaphragm comprising: a first substantially planar surface having a first end and a first bend wherein a distance between the first end and first bend defines a length and a height of said first planar surface, wherein said first end is fixedly attached to said disposable manifold, further wherein said height of said first planar surface is substantially equal to the height of said disposable manifold; a convex exterior surface continuing and protruding outward from said first bend of said first planar surface, said convex exterior surface continuing from said first bend to a second bend, wherein a distance between the first bend and second bend defines a length and height of said convex surface, wherein the convex surface at the first bend and the second bend has the same height as the first planar surface, wherein the height of said convex exterior surface increases from said first bend to a second height relative to the disposable manifold, and wherein the height of said convex exterior surface decreases from said second height to the second bend; and, a second substantially planar surface, continuing from said second bend to a second end, wherein a distance between the second bend and second end defines a length and a height of said second planar surface, wherein said second end is fixedly attached to said disposable manifold, further wherein said height of said second planar surface is substantially equal to said height of said first planar surface and said length of said second planar surface is substantially equal to said length of said first planar surface.
