Abstract

See full text

A valved catheter that allows placement and withdrawal of an accessing device or attachable unit without the risk of air embolism or blood loss. 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.
