14) stents
All mammals have arteries that allow blood to flow to the heart. If one of those arteries is clogged with plaque or is too narrow problems can arise for that mammal. A stent is a small mesh tube that is placed inside of an artery to strengthen or widen it so the problems can be fixed and/or prevented (ÒWhat Is a Stent?Ó). To place the stent in an artery, a doctor will cut a small opening in a blood vessel in the groin, arm or neck. Through the opening they insert a thin catheter that has a stent placed around a deflated balloon (ÒHow Are Stents Placed?Ó). The doctor will move the catheter through your body to the artery of concern by looking through a special x-ray machine. If the artery is full of plaque the doctor will inflate the balloon allowing the blood pressure to push the plaque out of the way (ÒHow Are Stents Placed?Ó). The inflation will also allow the stent to expand and push into the artery into place. Once the stent is in place the balloon will be deflated and the doctor will remove the catheter the way it came in. The incision where the catheter was inserted into the body is so small that the doctors just bandage it up and you donÕt need stitches. The blood from the injured site will clot and over time the epithelial cells in the epidermis will proliferate and cover the small incision leaving no visible traces that there was a cut.
