Preclinical testing
MRI safety: cobalt-chromium stents
In preclinical testing at a 3.0 T static field and an average SAR of 2.0 W/kg for 15 minutes, a single stent warmed by just over 1 °C and a pair of overlapping stents by less than 2 °C. MRI is acceptable up to 3 T, a spatial gradient of 720 G/cm and SAR 3.0 W/kg for 15 minutes; fields above 3.0 T were not studied.

Balloon diameter versus pressure (RAMA, NC RAMA)
For every nominal diameter the balloon diameter was measured from nominal to rated burst pressure. Nominal pressure: RAMA 6 atm, NC RAMA 12 atm. Rated burst pressure: RAMA 16 atm; NC RAMA 20 atm (Ø 1.50–4.00 mm) and 18 atm (Ø 4.25–5.00 mm). The table is on the product pages.
