The process of introducing a hollow, flexible tube into a blood vessel or body cavity to withdraw or instill fluids.

 

Threading of a flexible tube (catheter) through a channel in the body to inject drugs or a contrast medium, measure and record flow and pressures, inspect structures, take samples, diagnose disorders, or clear blockages. A cardiac catheter, passed into the heart through an artery or vein (the incision is often in the groin), can also carry pacemaker electrodes. A bladder catheter goes through the urethra into the bladder.

This type of physical manipulation is on the World Anti-Doping Agency's Prohibited list. See also tampering.
