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. 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.
Claims20
A valved catheter, comprising a catheter tube and a compression sleeve, said catheter tube comprising a first lumen separated from a second lumen by a septum, the catheter tube having a necked portion formed along a proximal section, said compression sleeve being positioned around said necked portion, to bias the first lumen and second lumen in a closed position.
A catheter, comprising:
- a catheter tube, including a first lumen separated along a length of the catheter tube from a second lumen by a septum, and a necked portion along a proximal section of the catheter tube;
- and
- a compression sleeve positioned about the necked portion, including a reduced diameter section that directs a force against the first lumen and second lumen, to bias the first lumen and second lumen in a closed position.
A catheter assembly, comprising:
- a catheter tube, including a first lumen separated from a second lumen by a septum and a necked portion positioned in a proximal end of the catheter tube;
- a compression sleeve positioned about the necked portion to bias the first lumen and second lumen in a closed position;
- and
- an attachable bifurcation having a portion configured for insertion into the first and second lumens such that upon attachment of the bifurcation to the catheter tube, the first and second lumens are open to fluid flow.
