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 rotationally activated flow control valve comprising,

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

a septum interposedly positioned between said distal adapter and said proximal adapter, said septum having a slit extending through said septum, said slit having two opposing slit surfaces, a contact portion of each of said two opposing slit surfaces being in contact when the septum is in a closed position, wherein said septum at least substantially seals said lumen, said septum further comprising at least two holes; and

at least two posts coupled to at least one of said proximal adapter and said distal adapter, wherein said two posts are mated with said holes when said valve is in the closed position,

wherein rotation of one of said proximal adapter or said distal adapter in relation to the other repositions said posts within said opening which 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 opening of said septum.

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 fully 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 said valve further comprises an interlok for receiving a second medical device, wherein upon rotationally coupling said second medical device to said interlok, said posts of said flow control valve are rotationally repositioned within said opening of said septum thereby activating said valve.

7. 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 the closed position.

8. The medical device of claim 7, wherein said septum further comprises a flat disc and sealing bead located on a proximal face of said disc.

9. The medical device of claim 8, wherein said sealing bead and said flat disc forms said fluid seal with said proximal adapter when said valve is in the closed position.

10. The medical device of claim 1, wherein rotation of said proximal adapter removes said posts from said holes which results in said posts deforming said opening to open said valve.

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

12. The medical device of claim 11, wherein disconnection of said second medical device from said body causes said valve to close.

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

14. 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.

15. 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 there through; and

a septum interposedly positioned between the at least two body sections, the septum having an opening, the opening including a slit and at least two holes, wherein said septum at least substantially seals said lumen; and

at least two posts coupled to at least one of the at least two body sections, a portion of said posts being disposed with a portion of said holes when the septum is in a closed position,

wherein rotation of at least one of said body sections in relation to said septum repositions said posts within said opening which results in the activation of said valve.

16. The medical device of claim 15, wherein the plane of rotation is substantially perpendicular to said lumen.

17. The medical device of claim 15, wherein said medical device is a vascular access device.
