Abstract
Connectors are provided for making connections between tubular conduits in medical procedures such as those involving treatment of a patient'"'"'s circulatory system. The connectors are variously configured for making end-to-side or end-to-end connections of tubular conduits. One of the tubular conduits may be a graft conduit, which can be artificial conduit, natural conduit, or a combination of both. The connectors for making end-to-side connections can be generally T-shaped or L-shaped. Various portions of the connectors can attach to the inside or outside of the associated conduit, depending on the connector configuration that is selected.
