  • Publication number: 20070255375
    Abstract: The present disclosure pertains to methods and apparatus for providing positive fixation of medical components to a portion of pericardial tissue via both vacuum- and/or mechanically-assisted means. According to the invention, 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. Other embodiment involve coupling a source fluid for delivery to the pericardial space (e.g., contrast media; saline solution; biological, genetic and pharmaceutical substances and the like).

  • Publication number: 20070255376
    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.

  • Publication number: 20070179388
    Abstract: A device and method of implanting a device for cardiac monitoring including a device can with one or more electrodes and one or more conductive bodies with one or more electrodes. The device may be implanted by measuring sequential surface ECG signals and identifying locations which produce signals having large magnitudes. The preferred location for implantation may be selected from these locations and the device may be implanted subdermally or intramuscullaryly in a position such that the device electrodes approximately correlate with the preferred electrode locations.
