1. A tissue penetrating catheter device useable with a magnetic resonance imaging system, said device comprising:

  • a catheter body having a distal end;

    a tissue penetrator that is advanceable from the catheter body; and

    at least one magnetic resonance apparatus that sends signals to a magnetic resonance imaging system adapted to use said signals to provide an indication of the position of said at least one magnetic resonance apparatus;

    wherein said at least one magnetic resonance apparatus comprises a first magnetic resonance apparatus located at a first location on or in the catheter body at or near the distal end of the catheter body, a second magnetic resonance apparatus located at a second location situated on or in the penetrator and a third magnetic resonance apparatus located at a third location on or in the catheter body at or near a location where the tissue penetrator advances out of the catheter body.
