patency
Quality of openness
Patency is the state of being open or unobstructed.
The term appears most often in medical contexts, describing whether tubes or passages allow flow: The surgeon confirmed patency of the artery.
A stent maintains patency in a blocked vessel.
Beyond medicine, patency can describe the openness of any channel or pathway, though this use is uncommon.
