A catheter is a medical device, essentially a tube, used in a wide range of medical procedures.

Certain catheters are designed to access veins and arteries. Vascular catheterization allows a physician to perform certain diagnostics that are otherwise impossible, such as sampling blood directly from the heart; measuring blood flow in the heart’s chambers; or evaluating blockages or abnormalities in the blood vessels outside the heart, such as the arms and legs.
