The term 'artery opener' refers to two medical procedures used to open blocked arteries. The first procedure is a stent, which is a small tube-like device that is inserted into the artery to keep it open. The second procedure is an AORTA, which is a surgical procedure that involves opening the AORTA and inserting a graft to keep the artery open. Both of these procedures are used to treat blocked arteries and improve blood flow.
