Interventional cardiovascular magnetic resonance (iCMR) can enable radiation-free catheterization procedures. However, the lack of MR-safe devices limits clinical iCMR procedures. An MR-safe, metal-braided catheter that avoids RF-heating at 1.5 Tesla was prototyped. RF-heating of the device was eliminated by virtue of segmenting its metal components. RF-safety and mechanical integrity were confirmed through in vitro tests per ASTM standards. The proposed method could be an attractive technique to construct MR-safe metal-braided catheters for iCMR procedures.
