A clinical-grade active MRI 0.035” guidewire design with a curved distal tip geometry and continuous shaft signal ensuring the mechanical and electrical safety, was introduced. Proposed design was tested in-vitro and in-vivo for MRI visibility and mechanical performance, and in-vitro for RF induced heating.
