The purpose of a vascular access device is to allow frequent access to a person's veins without having to stick them with intravenous (IV) needles or other large catheters. A chemo port is an example of a vascular access device that is sometimes implanted into individuals receiving infusion-based chemotherapy.
Vascular access devices are surgically implanted into a large vein near the heart and can stay in place for weeks, months, and even years. While they are often used to deliver chemotherapy drugs, a vascular access device can also be used to draw blood, deliver antibiotics and nutrition, and perform blood transfusions.
