DynamX™ – Bioadaptador

DynamX™ coronary bioadaptor is a next-generation device designed not only to treat obstructive lesions but also to progressively restore the vessel’s natural function. Unlike conventional drug-eluting stents, which maintain a rigid architecture, DynamX™ provides initial mechanical and antiproliferative support while enabling the vessel to gradually recover its mobility and physiological behavior.

The device is constructed from three 71 μm cobalt-chromium (CoCr) sinusoidal helical strands, arranged in a cylindrical configuration and linked by a biodegradable polymer base. This base provides rigidity during deployment and ensures adequate initial lesion support. The bioabsorbable coating consists of two layers: an outer 3 μm poly(lactic-co-glycolic acid) (PLGA) layer that releases sirolimus over approximately three months at a dose of 7 μg/mm, and an inner 6 μm poly-L-lactic acid (PLLA) layer that temporarily holds the helical strands together. The latter is progressively resorbed within six months.
