Place for a stent (5)
I believe the answer is:
aorta
'place for a stent' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aorta that I've seen before include "Great artery in body" , "Large artery of the heart" , "blood flows from it" , "Blood-carrier from a heart" , "Trunk route" .)
