PURPOSE: An invasive medical device is provided to exactly determine the location and orientation of a therapeutic or diagnostic device by using a probe and a display. CONSTITUTION: An apparatus for performing a medical procedure on a tissue within a body of a subject, comprises a wireless tag(20) configured to be fixed to the tissue and adapted to emit radiation, thereby causing first signals to be generated indicative of a location of the tag in the body, an invasive medical tool(32), and a processing unit. The invasive medical tool(32) further includes a probe(34) which is adapted to penetrate into the body so as to reach the tissue, a handle(36) fixed proximally to the probe and adapted to be manipulated by an operator of the tool, and a display(38) mounted on the handle and adapted to present a visual indication to the operator of an orientation of the probe relative to the tag. |
