A cardiovascular conduit system may comprise a connector. The connector may comprise a proximal end adapted to attach to a cardiovascular organ. The proximal end may comprise a first plurality of expandable members, and each member in the first plurality of expandable members may be deployable from a delivery position to a deployed position. The first plurality of expandable members may be dimensioned to deploy inside the cardiovascular organ to secure the connector to the cardiovascular organ. The connector may comprise a distal end adapted to attach to a conduit and an opening extending through the connector. Connectors for cardiovascular conduit systems may also include expandable stents. Connectors may be rotatably secured to a conduit, and the conduit may be reinforced. Methods for forming and using cardiovascular conduit systems are also disclosed.
