In medicine, a catheter is a tube that can be inserted into a body cavity, duct, or vessel. Catheters . In most uses, a catheter is a thin, flexible tube ("soft" catheter), though in some uses, it is a larger, solid ("hard") catheter. A catheter left inside the body, either temporarily or permanently, may be referred to as an indwelling catheter. A permanently inserted catheter may be referred to as a permcath.

Mummies show atherosclerosis was prevalent in ancient times

A new study published in the American Heart Journal used spectroscopic imaging techniques to ‘see’ fatty plaques in the arteries of ancient mummies. This shows that the people of ancient times also had a high incidence of clogged arteries, showing that heart disease is of very old lineage.
