The objective of this study was to perform in vitro and in vivo evaluation of hybrid devices that utilize mr-visible coatings for passive visualization of the entire length of a device, miniature RF-coils for accurate active tracking of the tip of a device tip, and inductively coupled self-resonators (wireless markers) to further improve passive visualization therapeutic devices such as catheters.
