Only the abluminal surface of the stent receives SMS treatment, allowing BA9™ to be contained within the micro-structured surface
and delivered with high specificity to the vessel wall of the coronary lesions.
The SMS process allows for an increased surface area for a uniform dose of BA9™ to be delivered to the target lesion.
With no need for polymer or carrier, BA9™ and SMS make BioFreedom™ Ultra a true Drug-Coated Stent (DCS).
