* As demonstrated in pre-clinical studies.

 

Supports, resorbs and restores, leading towards an event free future.
 
The three benefits of the Magmaris RMS technology directly translate into clinical results comparable to 2nd generation DES.
 
 
 
Target Lesion Failure (TLF)†† and Scaffold Thrombosis (ST) rates out to 36 months
TLF and ST rates in BIOSOLVE studies remain low and comparable to 2nd generation DES out to 36 months in similar patient population.
 
 
 
 
 
 



*    Tested up to 28 days in pre-clinical trials.
**  As demonstrated in pre-clinical studies.
†    Very late.
†† TLF defined as a composite of cardiac death, Target-Vessel MI and Clinically-Driven TLR.


 


DES-like vessel support.*

 
 
Magmaris acute recoil is comparable to modern DES6
No recoil increase is measured after one hour.7
 
 
 

 
 

The recoil rate is measured by calculating the difference between the diameter of the device at nominal pressure and the diameter of the device when no pressure is applied.

 
 

Similar mechanical properties translate into comparable clinical outcomes2,8
Multivariate adjustments showed that the device type was not an independent predictor of clinical adverse events.8

Magmaris has been shown to lower the risk of neoatherosclerosis*, a known risk for very late scaffold thrombosis.



55% less platelet coverage10

Magmaris and the custom-made stainless steel DES were implanted in a silicone tube and exposed to porcine blood flow for 1 hour.

The test was repeated with different positions for each device. After 1 hour, platelet coverage of the devices' surfaces was analyzed by immunostaining.

 




 
 
 
 
Neoatherosclerosis still a concern for the cardiology community
40% of patients who died 9 months after a DES implantation showed signs of neoatherosclerosis.11
 
 
 
 
 
 

*   As demonstrated in pre-clinical studies.
** Custom-made stainless steel DES with the same Magmaris design and coating.
†   Neoatherosclerosis is defined as the phenomenon of the transformation of stent neointima from normal neointima to an atherosclerotic lesion.

 
 
Formation of neoatherosclerosis


 
 
Magmaris exhibits greater endothelial integrity compared to a DES**,12

In a rabbit model, Magmaris shows tightly formed endothelial cell junctions compared to a custom-made stainless steel DES**.

Tightly packed endothelial cells reduce macrophages and cholesterol infiltration which in turn potentially reduces the risk of neoatherosclerosis, a predictor of very late events.


Greater endothelial integrity is associated with lower macrophages infiltration.13

 
Magmaris significantly reduces neo-intimal foamy macrophages compared to a DES**,12
The accumulation of foamy macrophages in the
neo-intimal space is an early sign of neoatherosclerosis.
 

Mean macrophage score reduction Magmaris vs. DES**:
p < 0.0001



 
 

Magmaris significantly
reduces the mean

** Custom-made stainless steel DES with the same Magmaris design and coating.


Mean neoatherosclerosis score reduction Magmaris vs. DES**:
p < 0.0001



The neoatherosclerosis score was assessed by histology and determines the quantity of
foam cells in different layers of the neointima.

 
 
 
Confidence through evidence

Magmaris shows a favorable healing profile and little progression of atherosclerosis over time.
