PERFEZIONAMENTI NEGLI STENT PER IL RILASCIO DI PRINCIPI ATTIVI

In an embodiment, a stent (S) implantable in a vessel of a patient, comprises recesses (200) loaded with an active principle with anti-inflammatory activity (10) and an active principle with anti-proliferative activity (20). The active principle with anti-inflammatory activity (10) and the active principle with anti-proliferative activity (20) have respective formulations, whereby the active principle with anti-inflammatory activity (10)and the active principle with anti-proliferative activity (20) have respective release kinetics as a function of said formulations, with the release of the active principle with anti-inflammatory activity (10) being faster than the release of the active principle with anti-proliferative activity (20).
