A central venous access catheter is a device that the physician inserts beneath the skin to draw blood or administer medication/nutrients to the patient. The catheter's tip must terminate in the brachiocephalic (innominate) or iliac vein, subclavian, the superior or inferior vena cava, or the right atrium. Tunneling describes a technique in which the physician places a long catheter under the skin between the vein entry and external access sites.
