dilators

Widen narrow passages

Dilators are instruments or devices used to widen or enlarge an opening or passage.

In medicine, dilators stretch body cavities or channels—cervical dilators prepare for procedures, urethral dilators address strictures, vaginal dilators treat conditions affecting intercourse or examination.

The term covers both medical tools and muscles that widen openings: pupil dilators respond to light.
