Stents are tiny, expandable tubes made of metal mesh that look similar to the spring
in a ball point pen. After the balloon angioplasty procedure opens the artery, a
stent is
placed
and expanded to fit the size, shape, and bend of the artery. The job of the stent
is to remain permanently in the artery to help keep blood flowing freely. Over time,
the artery wall heals around the stent.
Generally, there are few physical restrictions to worry about after having a stent
placement, and most are temporary. You should avoid strenuous exercise and physical
exertion for a short time. Be sure to discuss what level of activity is appropriate
for you with your doctor.
