Drug delivery connectors are provided for permitting and blocking fluid flow between a container and a catheter connector or other drug delivery site. Embodiments of the drug delivery connectors include a ball valve for forming a releasable seal within the drug delivery connectors. In one or more embodiments, the ball valve prevents fluid flow between an open proximal end and an open distal end of the drug delivery connector and is movable in a proximal direction to release the releasable seal to permit fluid flow from the open proximal direction to the open distal direction. Methods of delivering medication to a catheter connector that includes an actuator are also provided.

1. A drug delivery connector comprising: a housing including an open distal end, an open proximal end and a chamber within the housing in fluid communication with the open distal end and the open proximal end, the housing including a distal connection portion and a proximal connection portion for attaching the housing to a container;a ball valve enclosed within the chamber so that the ball valve floats between the open distal end and the open proximal end in the chamber, wherein the ball valve is moveable in a distal direction to form a releasable seal with the open distal end to prevent fluid flow from the open proximal end to the open distal end upon application of force in the distal direction on the ball valve applied by fluid upon attachment of a container containing the fluid to the proximal connection portion, the ball valve movable in a proximal direction to release the releasable seal to permit fluid flow from the open proximal end to the open distal end;an actuator for attachment to the open distal end of the housing, the actuator comprising an open distal end and a projection extending in the proximal direction and including at least one aperture in fluid communication with the open distal end of the actuator and the open distal end of the housing; anda structure that forms one or more fluid flow paths around the ball valve selected from one or more of a longitudinal protrusion, a rib, an expanding sidewall and combinations thereof. 2. The drug delivery connector of claim 1, wherein the housing comprises a proximal wall disposed adjacent to the open proximal end, the proximal wall including at least one aperture allowing constant fluid communication between the open proximal end and the chamber. 3. The drug delivery connector of claim 1, wherein the housing comprises a distal wall disposed adjacent to the open distal end, the distal wall including a bore having a perimeter, the perimeter configured to contact the ball valve to form a releasable seal between the ball valve and the distal wall. 4. The drug delivery connector of claim 1, wherein the distal connection portion comprises a luer lock fitting. 5. The drug delivery connector of claim 1, wherein the proximal connection portion comprises a luer lock fitting. 6. The drug delivery connector of claim 1, wherein upon attachment of the actuator to the open distal end of the housing, the projection applies a force on the ball valve in the proximal direction to move the ball valve in the proximal direction. 7. A drug delivery connector comprising a housing including an open distal end, an open proximal end and a chamber within the housing in fluid communication with the open distal end and the open proximal end, the housing including a distal connection portion and a proximal connection portion for attaching the housing to a container;a ball valve enclosed within the chamber so that the ball valve floats between the open distal end and the open proximal end in the chamber, wherein the ball valve is moveable in a distal direction to form a releasable seal with the open distal end to prevent fluid flow from the open proximal end to the open distal end upon application of force in the distal direction on the ball valve applied by fluid upon attachment of a container containing the fluid to the proximal connection portion, the ball valve movable in a proximal direction to release the releasable seal to permit fluid flow from the open proximal end to the open distal end; andan actuator for attachment to the open distal end of the housing, the actuator comprising an open distal end and a projection extending in the proximal direction and including at least one aperture in fluid communication with the open distal end of the actuator and the open distal end of the housing;wherein the housing comprises a retaining ring that inhibits movement of the ball valve in the proximal direction. 8. The drug delivery connector of claim 7, wherein the ball valve is movable in the proximal direction upon application of force in the proximal direction on the ball valve by the actuator, the force of the actuator being sufficient to overcome a distally directed force exerted on the ball valve by the retaining ring. 9. The drug delivery connector of claim 7, wherein the housing comprises a proximal wall disposed adjacent to the open proximal end, the proximal wall including at least one aperture allowing constant fluid communication between the open proximal end and the chamber. 10. The drug delivery connector of claim 7, wherein the housing comprises a distal wall disposed adjacent to the open distal end, the distal wall including a bore having a perimeter, the perimeter configured to contact the ball valve to form a releasable seal between the ball valve and the distal wall. 11. The drug delivery connector of claim 7, wherein the distal connection portion comprises a luer lock fitting. 12. The drug delivery connector of claim 7, wherein the proximal connection portion comprises a luer lock fitting. 13. The drug delivery connector of claim 7, wherein upon attachment of the actuator to the open distal end of the housing, the projection applies a force on the ball valve in the proximal direction to move the ball valve in the proximal direction.
