Pictogram illustrating Biomatrix Flex Biodegradable PolymerProven Safety of a DES
with an Abluminal Biodegradable Polymer


Confirmed Safety

With a 16% reduction in MACE compared to the Cypher® Select™ stent at 2 years in LEADERS2.

With no late or very late stent thrombosis in STEALTH I out to 4 years4.


Mortality benefit

The BioMatrix Flex™ stent reduces the cardiac death rate by 50.5% compared to the Cypher® Select™ stent at 2 years3.



Superior strut coverage

10 times better strut coverage of the BioMatrix Flex™ stent than the Cypher® Select™ stent at 9 months5-6.

The BioMatrix Flex™ stent achieves 96.4% of near to complete strut coverage.





Superior stent apposition

More than 20 times better stent apposition of the BioMatrix Flex™ stent than the Cypher® Select™ stent at 9 months5-6.


In the animal model, the BioMatrix Flex™ stent achieves a similar level of re-endothelialization compared to its bare metal stent platform.

BA9™ drug/Biodegradable PLA technology demonstrates preserved vasomotion7

Abnormal vasomotion (vasoconstriction) was observed for the sirolimus eluting stent group after high pacing stimulation, while normal vasomotion (vasodilatation) was observed in the BA9™ eluting stent group.
