BioFreedom - Selectively Micro-Structured Surface (SMS)

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 a true Drug-Coated Stent (DCS).
