Dissolvable Stent Improves Heart Attack Prevention


A new dissolvable stent is improving heart attack prevention.

Doctors say 70% blockage of an artery can be dangerous, and 90% can mean a heart attack. A typical fix when an artery is blocked is a stent made of medal mesh that expands to pop the artery open so blood can get through. But then that stent stays in place forever.

“After 6 months artery heals, then we’re left with the stent because we cannot pull it out and the patients don’t need it for the rest of their lives,” said the Director of Cardiovascular Research, Ron Waksman.

Researchers have created a new type of stent, that was manufactured by Abbott. It was approved by the FDA in July. It is put in place, then gradually absorbed by the body within three to four years. Doctors say that means patients have to work to keep their arteries clear.

So far, the new stent has been successful. It is already being used at a small number of hospitals.
