  • Implantable lead including sensor
    Patent number: 7254451
    Abstract: An implantable lead includes a defibrillation electrode and a sensor coupled thereto. The electrode and sensor are positioned along a body of the lead such that, when a fixation element couples the lead to an endocardial surface of a right ventricle, the sensor is located in a high flow region and a portion of the defibrillation electrode is located in proximity to a right ventricular apex.

  • Variable EGM filtering and fixation prediction
    Patent number: 7141017
    Abstract: An IMD includes a variable sense amplifier that can be adjusted to counteract the variability created in EGM's due to lead maturation. The effects of lead maturation are either predictively assumed or individually assessed on a given patient. The sense amplifier is then adjusted to assure positive identification of desired events and eliminate unwanted events.
