<p>Aspects of the present invention are directed generally toward a graft for use with a blood flow device that allows the use of a single blood flow device to simultaneously provide blood flow to the systemic and pulmonary circulations. One aspect of the invention is directed toward a graft comprising a tubular inlet portion coupleable to the outlet of the blood-flow assist device and configured to receive a flow of blood therethrough. The graft has a tubular systemic portion connected the inlet portion and configured to be connected to the systemic circulation of the patient to direct the first portion of the blood flow into the systemic circulation at a first flow rate. The graft has a tubular pulmonary portion connected to the inlet portion and configured to be connected to the pulmonary circulation of the patient to direct a second portion of the blood flow into the pulmonary circulation substantially simultaneous with delivery of the first portion of the blood flow into the systemic circulation.</p> |
