1. A vascular access device comprising:
a catheter comprising a primary lumen extending from a proximal end to a distal end of the catheter;
at least one deployable wire secured to the catheter and configured to move relative to the catheter between a delivery configuration and a deployed configuration; and
a guidewire,
wherein the at least one deployable wire in the deployed configuration is configured to engage an inner surface of a wall of a vessel, while allowing sufficient blood flow to pass through the vessel, and bias the catheter to engage the inner surface such that a hemostatic connection is formed between the catheter and the inner surface, the hemostatic connection being formed between a portion of an external surface of the catheter surrounding an access opening in a side wall of the catheter and the inner surface of the wall of the vessel,
wherein the guidewire is configured to be advanced through the primary lumen, the access opening, and the vessel wall to form an aperture, while maintaining the hemostatic connection, wherein the aperture extends from the inner surface of the vessel wall to an outer surface of the vessel wall,
wherein the catheter comprises a guidewire lumen further comprising a first portion, a second portion, and a seal positioned axially between the first portion and the second portion, wherein the guidewire lumen extends proximally from the distal end of the catheter to a lumen transition portion positioned axially between the guidewire lumen and the primary lumen.
