Prosthetic cardiac implant

A device (300) for use in total cavopulmonary connection, the device (300) comprising:

• a hollow body (302) comprising:
• a first end (304) configured to receive blood from inferior vena cava;
• and
• a second end (306) configured to be connected to pulmonary artery;
• and
• a flow separator (308) for guiding blood from inferior vena cava and superior vena cava to right pulmonary artery and left pulmonary artery, the flow separator (308) comprising an inferior end (402), a centre piece (414) and a superior end (404), wherein,
• the inferior end (402) is between the first end (304) and the second end (306) of the hollow body (302);
• the flow separator (308) is dimensioned to have the superior end (404) enter superior vena cava when the second end (306) is connected to the pulmonary artery;
• and
• the centre piece (414) defines a first pair of concave channels (406a and 406b) converging to define an inferior portion (410), wherein the pair of concave channels (406a and 406b) are configured to interface with blood from inferior vena cava and guide the blood from inferior vena cava to right pulmonary artery and left pulmonary artery.
