TCT 2009 TAXUS Liberte Atom Coronary Stent Designed for 2.25 mm Vessels Boston Scientific's TAXUS Liberte Atom Paclitaxel-Eluting Coronary Stent System is a next-generation drug-eluting stent (DES) specifically designed for treating small coronary vessels. It can be used in in vessels as small as 2.25 mm in diameter and joins the TAXUS Express Atom Stent as the only DES approved for small vessel use in the U.S. The TAXUS Liberte Atom features design improvements over the company's first-generation TAXUS Express Atom, including thinner struts to allow better stent deliverability and conformability, as well as uniform stent geometry for consistent lesion coverage and drug distribution, the company said. The FDA cleared the stent in May 2009. © 2010 Reilly Communications Group
