Printing press and antiseptic ointments.

- Printing press: Invented by Johannes Gutenberg in the mid‑15th century (c. 1440s).
- Antiseptic ointments/antiseptic techniques: Developed in the 19th century (notably Joseph Lister’s introduction of carbolic‑acid antisepsis in the 1860s).

Trepanation, bloodletting, and catheters predate the 14th century (they have ancient origins).
