A power source of an implantable medical device (IMD) is connected to one or more components that perform various functions of the IMD via an acoustic switching circuit. The acoustic switching circuit may include one or more switches that when open disconnect the one or more components from the power source and when closed connect the one or more components to the power source to activate the one or more components. Various techniques for connecting the components to the power source are described. These techniques aim to reduce the likelihood of inadvertently connecting the power source to the one or more components in response to acoustical signals from a source of interference.

Acoustic activation of components of an implantable medical device

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 to synchronize a location determination in a structure with a characteristic of the structure

Determining a location of a member

Formation of a feedthrough in a substrate for use in an implantable medical device is presented. A substrate includes a first surface and a second surface, and a via that extends through the first and the second surfaces. A dielectric layer is formed over one of a first surface of the substrate. Conductive material is introduced into the via to form a feedthrough.
