Magmaris®
Magmaris is the first clinically proven resorbable Magnesium scaffold.1-4 It is currently indicated for de novo lesions with a reference vessel diameter and lesion length closely matching the available Magmaris sizes.ᵃ⁵
Product Highlights
Confirmed clinical safety and efficacyb6-8
Confidence through evidence
Fast Magnesium resorption time
~95% of Magnesium resorbed at 12 months9
Better deliverabilityc10
Magnesium allows for a smoother scaffold surface11
Confirmed clinical safety and efficacyb6-8
Magmaris RMS has an excellent safety and efficacy profile up to 24-month follow-up.d12
Fast Magnesium resorption time9
The resorption process of Magnesium starts at the surface of the Magnesium backbone and continues inwards until only a footprint (amorphous calcium phosphate) is left.9
Better deliverabilityc10
More than 70% of physicians who have used Magmaris RMS in clinical practice have rated the device to be better than a polymeric scaffold.h11
