Abstract

A medical device having a vascular access device including a rotationally activated flow control valve having, a body including a distal adapter and a proximal adapter defining a lumen extending therethrough and a septum. A method of use in which the connection of first and second medical devices results in the automatic activation of the rotational flow control valve.

Claims

1. A medical device, comprising:

a vascular access device further comprising

a rotationally activated flow control valve, said flow control valve comprising,

a body including a distal adapter and a proximal adapter defining a lumen extending therethrough; and

a septum, wherein said septum at least substantially seals said lumen extending through said body;

wherein rotation of one of said proximal adapter or said distal adapter in relation to the other results in the activation of said valve.

2. The medical device of claim 1, wherein the plane of rotation is substantially perpendicular to said lumen.

3. The medical device of claim 1, wherein said rotation of said proximal adapter in relation to said distal adapter opens or closes said valve.

4. The medical device of claim 1, wherein a rotation of 90 degrees of one of said adapters in relation to said other adapter is required to activate said valve.

5. The medical device of claim 1, wherein the connection of a second medical device to said body causes the rotation of one of said proximal adapter or said distal adapter.

6. The medical device of claim 1, wherein the automatic activation of said valve occurs during the connection of a second medical device to said body.

7. The medical device of claim 1, wherein the automatic activation of said valve occurs after completion of the connection of a second medical device to said body.

8. The medical device of claim 1, wherein said septum is housed within said distal adapter and forms a fluid seal with said proximal adapter when said valve is in a closed position.

9. The medical device of claim 8, wherein said septum further comprises a disc and sealing bead located on a proximal face of said disc.

10. The medical device of claim 9, wherein said sealing bead and said disc forms said fluid seal with said proximal adapter when said valve is in a closed position.

11. The medical device of claim 9, wherein said disc further comprises at least two holes which are connected by a slit.

12. The medical device of claim 11, wherein said proximal adapter includes at least two posts which mate with said holes when said valve is in a closed position.

13. The medical device of claim 12, wherein rotation of said proximal adapter results in said posts deforming said slit to open said valve.

14. The medical device of claim 1, wherein the connection of a second medical device to said body causes said valve to open.

15. The medical device of claim 14, wherein disconnection of said second medical device from said body causes said valve to close.

16. The medical device of claim 1, wherein said vascular access device is a catheter.

17. The medical device of claim 1, wherein said proximal adapter further comprises a connection region to enable said vascular access device to be selectively coupled to other medical devices.

18. The medical device of claim 17 wherein said connection region is a female luer lock connector or a male luer lock connector.

19. A method, comprising:

providing a first medical device having a lumen and rotationally activated valve,

connecting a second medical device having a lumen to said first medical device such that said rotationally activated valve is automatically opened and said lumen are in fluid communication.

20. The method of claim 19, wherein the plane of rotation is substantially perpendicular to said lumen.

21. The method of claim 19, further comprising the step of:

disconnecting said second medical device from said first medical device such that said rotationally activated valve is automatically closed.

22. The method of claim 19, wherein the automatic activation of said valve occurs during the connection of said second medical device to said first medical device.

23. The method of claim 19, wherein the automatic activation of said valve occurs after completion of the connection of said second medical device to said first medical device.

24. A medical device comprising

a rotationally activated flow control valve, said flow control valve comprising,

a body including at least two body sections, defining a lumen extending therethrough;

and

a septum, wherein said septum at least substantially seals said lumen extending through said body;

wherein rotation of at least one of said body sections in relation to said septum results in the activation of said valve.

25. The medical device of claim 24, wherein the plane of rotation is substantially perpendicular to said lumen.

26. The medical device of claim 24, wherein said medical device is a vascular access device.
