Abstract
Valve assemblies having improved ability to selectively control flow of fluids through the catheter and prevent leakage of fluids from the proximal end of a catheter that is positioned within a patient. Such improved catheter valve assemblies also prevent leakage of fluids after repeated insertion and removal of medical instruments through the valve.
Claims19
A valve assembly configured for use with a male luer having a distal end, a lateral surface and a connector portion, the valve assembly comprising:
- a hub configured to receive the male luer in a proximal end, the hub comprising an inner surface;
- a valve in fluid communication with the hub, the valve comprising a barrier layer at a distal end of the valve and a wall portion extending proximally from the barrier layer to a proximal end of the valve, the wall portion defining a valve cavity therein;
- the barrier layer comprising one or more slits;
- a flange portion at the proximal end of the valve, wherein a proximal end of the flange portion extends beyond the proximal end of the hub;
- wherein the barrier layer is configured to open by elastic deformation;
- and
- wherein a thickness of the barrier layer is greater than an offset distance measured between an inner surface of the wall portion and the inner surface of the hub.
A valve assembly configured for use with a male luer having a distal end, a lateral surface and a connector portion, the valve assembly comprising:
- a hub configured to receive the male luer in a proximal end, the hub comprising an inner surface;
- a valve in fluid communication with the hub, the valve comprising a barrier layer at a distal end of the valve and a wall portion extending proximally from the barrier layer to a proximal end of the valve, the wall portion defining a valve cavity therein;
- the barrier layer comprising one or more slits;
- wherein the barrier layer is configured to open by elastic deformation;
- wherein a thickness of the barrier layer is greater than an offset distance measured between an inner surface of the wall portion and the inner surface of the hub;
- and
- wherein the proximal end of the valve is flush with the proximal end of the hub.

- wherein the barrier layer is configured to open by elastic deformation;
- and
- wherein a thickness of the barrier layer is greater than an offset distance measured between an inner surface of the wall portion and the inner surface of the hub;
- and
- where an entire outer surface of the wall portion contacts the inner surface of the hub.
