A source tells CNBC that former President Bill Clinton received two drug-coated stents, called "Xience," made by Abbott Labs .
A spokesperson for New York-Presbyterian Hospital/Columbia University Medical Center would not confirm or deny the information, telling CNBC, "We are not providing the brand of the stent or the manufacturer." At a news conference Thursday evening Clinton's cardiologist also declined to answer a reporter's question about the type, brand or manufacturer of the two stents.
Stents are tiny wire mesh tubes that prop open clogged arteries.
There are bare-metal stents and more expensive drug-coated stents, which are believed to prevent artery reclogging better than the uncoated ones. Abbott, Boston Scientific, Johnson & Johnson and Medtronic make them. The Xience stent is one of the newest ones on the market. Boston Scientific sells the exact same stent, but under a different brand name: "Promus."
ABT sold $1 billion worth of stents in the U.S. last year, an increase of 54 percent from the year before.
