What Are Vascular Access Devices?
Vascular access devices (VADs) are medical devices that are placed under the skin to allow for repeated access to a patient’s veins. They are most commonly used in patients who require long-term intravenous (IV) therapy, such as those with cancer or chronic illnesses. VADs include peripherally inserted central catheters (PICCs), implanted ports, and hemodialysis catheters.
