The stents are not absorbed into the body. Today the stents are coated with drugs which are released into the blood to prevent clot and thrombus formation. This drug is absorbed over a period of time (spanning years). There after if the person is prone to thrombus formation the stent can get occluded. Sometimes the stent gets blocked because of the blood flow patterns or because the blood is too thick.
It is difficult to say how many stents can be put in. While 5 or more stents can be placed safely, often a person requiring multiple stents is an ideal candidate for bypass surgery which works out to be a safer option for him than going again and again for stents.
Please discuss this with your cardiologist. Hope this helps. Take care!
