Abstract
An improved intracorporeal device such as a guide wire or other guiding member for use within a patient's body that is at least in part visible under magnetic resonance imaging (MRI) but is not detrimentally affected by the imaging is disclosed. The intercorporeal device has a non-conductive proximal core section, an essentially non-magnetic metallic distal core section that is preferably more flexible than the proximal core section, and that has an MRI visible member or coil in the distal section.
