  • METHODS AND DEVICES FOR ACCURATELY CLASSIFYING CARDIAC ACTIVITY
    Publication number: 20140046204
    Abstract: Methods, systems, and devices for signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In illustrative examples, captured data including detected events is analyzed to identify likely overdetection of cardiac events. In some illustrative examples, when overdetection is identified, data may be modified to correct for overdetection, to reduce the impact of overdetection, or to ignore overdetected data. New methods for organizing the use of morphology and rate analysis in an overall architecture for rhythm classification and cardiac signal analysis are also discussed.

  • ACCURATE CARDIAC EVENT DETECTION IN AN IMPLANTABLE CARDIAC STIMULUS DEVICE
    Publication number: 20140046394
    Abstract: Methods, systems, and devices for signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In some illustrative examples, detected events are analyzed to identify changes in detected event amplitudes. When detected event amplitudes are dissimilar from one another, a first set of detection parameters may be invoked, and, when detected event amplitudes are similar to one another, a second set of detection parameters may be invoked. Additional methods determine whether the calculated heart rate is “high” or “low,” and then may select a third set of detection parameters for use when the calculated heart rate is high.

  • ROBUST RATE CALCULATION IN AN IMPLANTABLE CARDIAC STIMULUS OR MONITORING DEVICE
    Publication number: 20140046206
    Abstract: Devices and methods for analyzing cardiac signal data. An illustrative method includes identifying a plurality of detected events and measuring intervals between the detected events for use in rate estimation. In the illustrative embodiment, a set of intervals is used to make the rate estimation by first discarding selected intervals from the set. The remaining intervals are then used to calculate an estimated interval, for example by averaging the remaining intervals.

In some examples, captured data including detected events is analyzed to identify likely overdetection of cardiac events. In some illustrative examples, when overdetection is identified, data may be modified to correct for overdetection, to reduce the impact of overdetection, or to ignore overdetected data. Several examples emphasize the use of morphology analysis using correlation to static templates and/or inter-event correlation analysis.

  • Method and devices for performing cardiac waveform appraisal
    Patent number: 8626285
    Abstract: Implementations of various technologies described herein are directed toward a sensing architecture for use in cardiac rhythm management devices. The sensing architecture may provide a method and means for certifying detected events by the cardiac rhythm management device. Moreover, by exploiting the enhanced capability to accurately identifying only those sensed events that are desirable, and preventing the use of events marked as suspect, the sensing architecture can better discriminate between rhythms appropriate for device therapy and those that are not.

  • Coronary vein leads having pre-formed biased portions for fixation
    Patent number: 8498721
    Abstract: A lead having a pre-formed biased portion is adapted for implantation with a body vessel and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are biased toward a vessel wall by the preformed biased portion, which operates to fixate the lead against the vessel wall.

  • Laminated insulated timber for building construction
    Patent number: 8448396
    Abstract: A laminated insulated timber is described possessing a laminate essentially composed of plurality of side planks, a top plank and a bottom plank that box in an insulation member. The planks are offset relative to one another to form a tongue and groove arrangement. In this manner, other like laminated insulated timbers join together along the tongue and groove arrangements to interlock and stack, thus forming a structural wall of laminated insulated timbers.
