  • Patent number: 6430440
    Abstract: An implantable cardiac stimulation device including an activity/position sensor that incorporates a magnetoresistive sensor and a magnet that are positioned so as to move relative to each other in response to activity and the body position of the patient when the device is implanted in the body of the patient. In one embodiment, the sensor includes a magnetoresistive sensor that is made from giant magnetoresistive (GMR) materials. Preferably, a magnet is positioned on a flexible cantilevered beam so as to be positioned adjacent the magnetoresistive sensor. Movement of the patient results in relative movement of the magnet with respect to the magnetoresistive sensor and generates a signal having an AC component corresponding to a patient's activity and a DC component corresponding to the patient's body position.

In one embodiment, the sensor includes a magnetoresistive sensor that is made from giant magnetoresistive (GMR) materials. In another embodiment, a magnet is positioned on a flexible cantilevered beam so as to be positioned adjacent the magnetoresistive sensor. Movement of the patient results in relative movement of the magnet with respect to the magnetoresistive sensor. The signal can be used by the implantable cardiac device's processor for adjusting the delivery of therapeutic electrical stimulation such as by adjusting the pacing rate of pacing pulses being delivered to the patient's heart.

  • Patent number: 5810739
    Abstract: Methods and apparatus are provided for classifying cardiac events with an implantable cardiac device. Cardiac signals are stored in a buffer. When a significant cardiac event is confirmed, a corresponding segment of the stored cardiac signals is processed to generate a set of feature values. The set of feature values is compared to various sets of reference values. Each set of reference values preferably corresponds to a separate type of cardiac event, so that the cardiac device may classify the significant cardiac event by matching its set of feature values to a set of reference values.

  • Patent number: 5755741
    Abstract: A sensor that is implantable within the body of a patient that provides an indication of movement and orientation of the patient. The sensor is comprised of a cylindrical enclosure having a central electrode positioned within the cavity formed by the enclosure that is co-axial with the axis of the cylinder. One or more peripheral electrodes are positioned within the cavity and extend in a direction parallel to the central electrode. An electrolytic fluid is positioned in the enclosure so that movement of the sensor results in variations in the amount of electrolytic solution between the central electrode and the one or more peripheral electrodes. An alternating current signal is applied to the central electrode and the one or more peripheral electrodes and the resulting voltage signal is measured between the central electrode and the one or more peripheral electrodes.
