Title:
ＭＲＩに対して安全な折り畳み式コイルアセンブリ
Document Type and Number:
Japanese Patent JP7258848
Kind Code:
B2
Abstract:
Implants or sensors often include and rely on inductive and ferromagnetic electrical components to measure and communicate data outside of the body to an external device, creating a safety concern when a patient with these implants or sensors must undergo an MRI scan. Further, various external devices that include inductive and ferromagnetic electrical components are exposed to potentially damaging MRI scans. An electrical coil assembly can include an electrical coil that includes a substrate and an electrical conductor supported by a first face of the substrate. In an example, the electrical coil assembly further includes a fuse element that is configured to move from a disengaged position in which the electrical fuse conductor is out of contact with the electrical conductor to an engaged position in which the electrical fuse conductor contacts the electrical conductor so as to define a short circuit.
