Inside the new stent that expands, contracts, and remodels with your heart

The article discusses a groundbreaking stent technology called DynamX, developed by Dr. Tamil Muthusamy, an interventional cardiologist. Unlike traditional drug-eluting stents (DES) that are rigid and can cause long-term complications due to their inability to move with the natural dynamics of the heart’s arteries, DynamX is designed to expand, contract, and remodel in sync with the artery. Traditional stents, while effective initially, have a 2–3% annual failure rate over ten years, leading to significant repeat procedures. This is largely because rigid stents restrict the artery’s natural pulsatility and rotational movements, especially in critical vessels like the left anterior descending artery (LAD), causing biological stress, cell damage, and excessive scar tissue formation. DynamX addresses these issues by using three interlocked helical coils held rigid by bioabsorbable polymers during the early healing phase. After about six months, the polymers dissolve, allowing the coils to unlock and the stent to
