Abstract: 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.

Abstract: Certain aspects of the disclosure pertain to methods and apparatus for providing positive fixation of medical components to a portion of incised pericardial tissue. Accordingly, a resilient member protrudes through an incision in the pericardium and produces a positive biasing force to adjacent pericardial tissue against a side surface of an attached body structure. The resilient member can optionally be compressed during implantation and then relaxed to thereafter provide the positive biasing force. Diverse medical components can thus be safely and reliably chronically deployed into the pericardial space, including without limitation, cardiac sensing/pacing, defibrillation and/or cardioversion electrodes, mechanical and/or metabolic sensors and the like. More than one body structure can be linked to a single medical electrical lead and the medical components can couple within and/or upon a portion of the body structure, the resilient member, and the lead in myriad configurations.

Abstract: A method and apparatus for providing positive fixation of medical components to a portion of pericardial tissue via both vacuum- and/or mechanically-assisted means. A source of vacuum couples via a lumen to a recessed portion of a body structure deployed into the pericardial space. The recessed portion is adapted to form a seal around its periphery with adjacent pericardial tissue so that when the recessed portion is evacuated, the tissue is drawn into the recessed portion. Then, a sharpened instrument, such as a stylet, is deployed through the lumen and pierces the tissue, thus anchoring the body structure. A source of fluid may also be included for delivery to the pericardial space (e.g., contrast media; saline solution; biological, genetic and pharmaceutical substances and the like).

Abstract: Displacement or migration of a left ventricular lead located within the coronary sinus or coronary veins of the heart is detected by comparing an electrogram (EGM) waveform pattern from the lead with a stored baseline EGM waveform pattern. Based upon the extent of lead migration, if any, a lead displacement may produce an annunciating response. The patient may be alerted, an electrical stimulus applied through the lead may be adjusted to compensate for lead migration, or an alternative electrode on the lead may be used for EGM sensing and pacing.
