Catheter

/ˈkæθɪtər/noun

A thin tube passed into the body to drain fluid or deliver treatment.

The Greek roots

κατά
katá
down
+
ἱέναι
hiénai
to send, let go

Literally: thing let down

The story of the word

The Greek word also named a plumb line, the weight let straight down to test a wall, and the sense of lowering something in is the common thread. Bronze S-curved catheters for urinary retention survive from Pompeii, so the instrument is older than the English word by fifteen centuries. Benjamin Franklin had a jointed silver one made in 1752 for his brother John, who was in agony with bladder stones.
