An area of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of an area or volume can be determined based upon the sensing of the plurality of points without the use of an imaging device. An implantable medical device can then be navigated relative to the mapping data.

Method and apparatus for mapping a structure

An volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.

Tracking a guide member

Interference blocking and frequency selection

A system for determining a location of an instrument within an anatomy is provided. The system can include a first instrument, which can define at least one lumen. The system can further include a second instrument, which can be received through the at least one lumen. The system can include at least one electrode, which can be coupled to a distal end of the first instrument. The electrode can be responsive to electrical activity to generate at least one signal. The system can include a sensing unit, which can be in contact with the anatomy to sense electrical activity within the anatomy at a location near the instrument. The sensing unit can be in communication with the electrode to receive the signal. The system can further include a control module that can determine, based on the sensed electrical activity and the signal, the location of the first instrument.
