Abstract
A valved catheter that allows placement and withdrawal of an accessing device or attachable unit without the risk of air embolism or blood loss. In one variation, the valved catheter includes a catheter tube having a necked portion in its proximal end that forms an integral valve, the necked portion being surrounded by a compression sleeve that biases the valve in a closed position. In another variation, the valved catheter is a dual lumen catheter with a corresponding bifurcating extension for engaging the valves in the catheter in order to establish fluid communication through the catheter.
