A catheter assembly includes a catheter packaged inside of a handle that is attached to a container. The catheter has a distal end portion that includes a valve. The valve includes a protrusion coupled to an exterior of a distal end portion of the catheter. The handle has a cavity with a flange is formed on an interior surface of the cavity. The flange is sized to engage with the protrusion coupled to the catheter, and the valve of the catheter opens when the protrusion of the catheter contacts the flange.
