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.

Method and apparatus for mapping a structure

A method and apparatus for tracking and illustrating the location of leads positioned within the volume is disclosed. For example, the lead electrodes can be positioned within a heart of a patient that can be tracked over time. The lead electrodes can be tracked with an electrode potential or bioimpedance tracking system to determine the position of the lead electrodes. A method and apparatus is disclosed to analyze the position information for analyzing the selected position of the lead electrodes.

System and method to evaluate electrode position and spacing

Techniques related to coils for medical device are disclosed. One example coil may comprise multiple filars, each being formed of a biocompatible beta titanium alloy having an elastic modulus ranging from 30 GigaPascals (GPa) to 90 GPa and comprising at least two elements from a group consisting of titanium, molybdenum, niobium, tantalum, zirconium, chromium, iron and tin. At least one of the multiple filars may be electrically insulated one from another. A structural body, such as a lead body, may carry the coil. One or more filars may carry a low-resistance core.
