Abstract:
A few decades ago, most people suffering from partially clogged arteries had to undergo bypass surgery to alleviate their coronary problems. That changed with the advent of the Roto-Rooter procedure known as angioplasty and micromachined stents that then kept arteries propped open. The medical industry went one step further recently by offering drug-releasing stents that help prevent life-threatening clots from forming after implantation.
