  • Patent number: 7729765
    Abstract: A system and method for passively testing a cardiac pacemaker in which sensing signal amplitudes and lead impedance values are measured and stored while the pacemaker is functioning in its programmed mode. The amplitude and impedance data may be gotten and stored periodically at regular intervals to generate a historical record for diagnostic purposes. Sensing signal amplitudes may also be measured and stored from a sensing channel which is currently not programmed to be active as long as the pacemaker is physically configured to support the sensing channel. Such data can be useful in evaluating whether a switch in the pacemaker's operating mode is desirable.

  • Patent number: 7715921
    Abstract: As compared to conventional electrodes, the electrode configurations disclosed herein minimize irritation and damage to the skin when they are placed in contact with a patient's body over extended of time. The electrodes are formed from a conductive substrate coated with a thin dielectric material, and a plurality of open spaces pass through the electrodes. Those open spaces are distributed and sized to permit moisture on the surface of the patient's body to escape when the electrode is placed in contact with the patient's body. One intended use for the electrodes is for treating tumors by applying an AC electric field with specific frequency and field strength characteristics over an extended period of time.

  • Patent number: 7706881
    Abstract: Techniques are provided for improving cardiac output and also suppressing certain forms of apnea/hypopnea within a patient using an implantable medical device, such as a pacemaker or ICD. In one example, a selected pacing parameter—usually the pacing rate—is temporarily altered by an amount sufficient to elevate cardiac output, the elevation in cardiac output being eventually reduced by intrinsic compensatory mechanisms within the patient. The pacing parameter is then temporarily reset for a duration sufficient to allow the compensatory mechanisms to return toward a previous state so as to permit a subsequent alteration in the pacing parameter to again elevate cardiac output. The pacing parameter is repeatedly altered and reset so as to achieve an overall increase in cardiac output despite the intrinsic compensatory mechanisms. The increase in cardiac output is often sufficient to suppress certain forms of apnea/hypopnea, particularly apnea/hypopnea arising from Cheyne-Stokes Respiration (CSR).

  • Patent number: 7676275
    Abstract: A lead of the present invention comprises an electrode array adapted to be stably anchored at a selected location within the vena cava of a human patient. The electrode array may take various shapes, including helical, annular and linear. The electrode array is connectable to an electrical stimulation means such as an implantable pulse or signal generator. Electrical stimulation applied to a selected region of the vena cava and across the wall of the vein, that is, transvascularly, to the vagus nerve or branches thereof, depolarizes the nerve to thereby effect control of the heart rate.

  • Patent number: 7672736
    Abstract: A reinforced medical electrical lead for neurological applications has a reinforced construction for resisting the detachment of electrodes and lead connection terminals, thereby improving the robustness of the lead and extending the life of the lead by reducing the likelihood that a further surgical procedure will be required to remove the lead for repair or replacement thereof. The present reinforced lead construction maintains the integrity of the electrical connection between the conductor and the respective electrode and lead connection terminal by incorporating several reinforcing features in the lead construction in contrast to conventional lead constructions where it is possible to pull the electrodes and lead connection terminals away from their contact points with relatively little force.

  • Patent number: 7664549
    Abstract: A system, method, or device classifies an arrhythmia according to the temporal order in which a depolarization wave associated with a particular heart contraction is received at a plurality of electrodes. One or more antiarrhythmia therapies is mapped to each arrhythmia classification. When a particularly classified arrhythmia is detected, the correspondingly mapped therapy list is selected and an appropriate antiarrhythmia therapy delivered. In one example, the particular therapy delivered in response to an arrhythmia depends at least in part on its historical success in treating arrhythmias of that classification.

  • Patent number: 7657306
    Abstract: A method of and a device for non-invasively measuring the hemodynamic state of a subject or a human patient involve steps and units of non-invasively measuring cardiac cycle period, electrical-mechanical interval, mean arterial pressure, and ejection interval and converting the measured electrical-mechanical interval, mean arterial pressure and ejection interval into the cardiac parameters such as Preload, Afterload and Contractility, which are the common cardiac parameters used by an anesthesiologist. The converted hemodynamic state of a patient is displayed on a screen as a three-dimensional vector with each of its three coordinates respectively representing Preload, Afterload and Contractility. Therefore, a medical practitioner looks at the screen and quickly obtains the important and necessary information.
