The Apollo Hospitals, one of the six centres in India to be part of a global trial on using drug-eluting bio-resorbable stents, are the first in Chennai to use the product.

The device works like a regular stent by restoring blood flow to a clogged vessel. It also contains a drug that is slowly released to help the healing process.

But what stands out is the fact that the stent dissolves harmlessly inside the blood vessel and restores flexibility of the affected vessel.
