Pulmonary circulation assist implant for a univentricular heart

A Pulmonary Circulation Assist Implant 200 configured to separate bloodstream from an IVC and bloodstream from an SVC to circumvent collision between the bloodstreams without providing an offset, said implant comprising:

• a long conduit 70 crossing an operative transverse short conduit with a junction being formed at said crossing, said long conduit 70 and said short conduit forming a cross,
• said long conduit 70 having a first open long end 40 and a second open long end 60, with said junction therebetween, said first open long end 40 being configured to be anastomosed with a Superior Vena Cava (SVC), said second open long end 60 being configured to be anastomosed with an Inferior Vena Cava (IVC);
• said short conduit having a first open short end 30 and a second open short end 50, with said junction therebetween, said first open short end 30 being configured to be anastomosed with a Left Pulmonary Artery (LPA), said second open short end 50 being configured to be anastomosed with a Right Pulmonary Artery (RPA);
• and
• a flow manipulator 100 being provided at said junction, said flow manipulator 100 configured to, smoothly, regulate blood flows from said Superior Vena Cava (SVC) and said Inferior Vena Cava (IVC) to said Left Pulmonary Artery (LPA) and said Right Pulmonary Artery (RPA), respectively, by forming four distinct quadrants, for smooth curvilinear flows of blood streams entering through said ends 40, 60 of said long conduit and exiting through said ends 30, 50 of said short conduit.
