An extravascular system for accessing the vasculature of a patient including a catheter having an interior surface, a needle disposed within the catheter, and/or a needle cap defining at least one capillary space and including a flexible seal surrounding the at least one capillary space. The flexible seal may engage the interior surface of the catheter. A method of controlling exposure to a liquid from an extravascular system including providing a wicking material positioned adjacent to a flow channel such that any fluid located external to the flow channel is retained by the wicking material. The wicking material may be incorporated into any extravascular system where exposure to liquids is undesirable.

Vascular access device blood sealing and exposure prevention

A tip shield of a catheter assembly has a resilient clip compartment, which may become blood-filled during use of the catheter assembly. The resilient clip inside the compartment is released upon withdrawal of the needle of the catheter assembly to disengage the catheter hub from the tip shield. The resilient clip also prevents re-exposure of the needle after being withdrawn into the tip shield. The blood-filled compartment may potentially leak or splash through an opening from the compartment when the resilient clip is released. A covering blocks the opening from the tip shield to minimize the risk of blood exposure. In addition, the covering minimizes the risk of premature release of the resilient clip and re-exposure of the needle.
