Pronunciation

  • UK: /ˈkæθɪtə(ɹ)/[1]
  • US: /ˈkæθɪtɚ/[1]

Etymology

It is borrowed from Late Latin cathetēr,[2][3][4][5][6] according to Barnhart and Etymonline by way of French cathéter,[7][8][1] from Ancient Greek καθετήρ (kathetḗr, “anything let down into; a catheter”),[2][9][8] formed from καθίημι (kathíēmi, “to send or let down”) with the agent suffix -τήρ (-tḗr).[10][6][1] The verb is formed from κατά (katá, “down”) and ἵημι (híēmi, “to send”),[3][9][8] which Klein connects with Latin iaciō (“to throw”);[9] Etymonline and the American Heritage Dictionary trace it to Proto-Indo-European *yē- (“to throw, impel”).[8][3] The English word replaced the earlier cathirum (probably before 1425), from Medieval Latin cathirum,[7][8] and Middle English also had argalia for the instrument, through Medieval Latin from Arabic.[8]

Earliest recorded meaning

A tube passed into the bladder to draw off urine: 1601, in John Manningham's diary,[2][7][4] about 1600 in Etymonline.[8]

Semantic evolution

Johnson (1755) described it as a hollow, somewhat curved instrument thrust into the bladder to bring away urine when a stone or gravel blocks the passage.[11] The OED's definition, written in 1889, speaks of a tube of metal or rubber, and of similar tubes for other canals of the body;[2] modern dictionaries define it as any tube put into a body passage, vessel or cavity to let fluids in or out, or to keep a passage open.[4][12] The derivative catheterization dates from the mid 19th century.[5]
