With 5.5-mm post-dilatation capability for 3.5-mm and 4.0-mm stents, XIENCE Sierra™ Stent can treat large vessels.
And with 3.75-mm post-dilatation capability for smaller diameter stents—2.25 mm, 2.5 mm, 2.75 mm, 3.0 mm, and 3.25 mm—XIENCE Sierra™ Stent can also treat tapered vessels of various diameters.
These options for stent diameters and post-expansion diameters provide a range of choices to treat the array of vessels that interventional cardiologists (ICs) encounter.
