| Crossing profile (trackability; pushability) |
Method: The diameter of the scaffold mounted on its delivery system was photographed in air, rotated 90° then photographed again for measurements; results: 1.44±0.02 mm (major than Xpedition) |
Trackability: the system is able to measure proximal and distal forces during the passage of the stent system through the guiding catheter and the vessel model with a simulated vessel curvature; results: mean track force 0.64±0.02 N (more trackability than ABSORB and MAGMARIS); pushability: It was measured using the trackability setup, simulating vessel curvature and total occlusion model at the end; results: 36.27%±1.30% (minor pushability than MAGMARIS but major than ABSORB) |
| Acute recoil |
Method: 3.5 mm scaffolds were expanded unconstrained in a water bath at 37 °C at nominal pressure and photographed at one, 10 and 60 minutes; results: 1 min → DESolve recoiled 0.1 mm; 10 min → no change; 60 min → DESolve increased in diameter up to 3.52±0.14 mm (self-correction) (different behaviour than ABSORB and Xpedition) |
Method A: recoil without outer loading acute and after 1 h (scaffold expansion up to the nominal pressure 9 atm in 2 s intervals per atm); results: acute elastic recoil (7.85%), after 1 h the diameter increased by about 3%. Method B: Recoil with outer loading through mock vessel (light 40 mm, inner diameter 2.7±0.2 mm, radial compliance 5–7% per 100 mmHg. 72 bpm); results: after 1 h diameter decreased by more 11% (different behaviour than ABSORB and MAGMARIS) |
| Radial strength |
Method: the pressures needed to reduce the device cross-sectional area by 25% were assessed; results: 1.1±0.1 atm (minor than ABSORB and Xpedition) |
No data available |
| Strut fracture (main branch post-dilatation) |
Method: post-dilatation with increasing NC balloon size up to 20 atm pressure or until a strut fracture; results: stent fracture caused by balloon 5.0 mm at 21 atm (better than ABSORB and Xpedition) |
No data available |
| Scaffold fracture (side branch dilatation) |
Method: side branches were dilated with NC balloons of increasing diameters; results: no fracture (better than ABSORB) |
No data available |
| Bending stiffness |
No data available |
Method: experimental setup where the test sample is fixed at the free bending length l and deflected by the distance F; results: 21.25 N·mm−2 (twice more flexible than ABSORB and MAGMARIS) |
