Claims20
An omnidirectional MRI resonant marker, comprising:
- a) a tunable capacitor;
- b) a conductor formed into a conductor coil, the conductor coil operably coupled to the tunable capacitor, wherein the conductor coil is configured to be associated with a medical device.
An omnidirectional MRI resonant marker, comprising:
- a) a tunable capacitor configured to be tunable by modification of the capacitor;
- and
- b) a conductor formed into a conductor coil, the conductor coil operably coupled to the tunable capacitor, wherein the conductor coil comprises a double helix configuration and is configured to be associated with a catheter.
An omnidirectional MRI trackable catheter, comprising:
- a) a catheter body;
- b) a conductor formed into a double helix conductor coil, wherein the conductor coil is associated with the catheter body, wherein at least one portion of the conductor coil is perpendicular to a magnetic resonance field;
- and
- c) a tunable capacitor operably coupled to and integral with the conductor coil, wherein the tunable capacitor is configured to be tunable by modification of the capacitor.
