  • Patent number: 12144637
    Abstract: Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals.

  • Patent number: 12053141
    Abstract: A wand includes a hinge configured to pivotally connect first and second wand segments in an extended configuration and a storage configuration. A first locking mechanism locks the wand in extended configuration. A second locking mechanism includes a rod, a sliding lever, a plunger, and a plunger cavity. The plunger is configured to be received in the plunger cavity to lock the wand in the storage configuration. When in the extended configuration, depressing a single actuator pivots the locking arm, causes the hook/pawl to be removed from the locking cavity, and unlocks the wand. When in the storage configuration, depressing the single actuator causes the rod to move in a first direction, causes the sliding rod to move a second direction, and urges the plunger out of the plunger cavity.

  • Publication number: 20240254579
    Abstract: An automated plate shaping and verification system allows for the accurate and efficient transformation of a metal plate from a starting shape to a target shape. Using a method for path planning, the system can select heating patterns based on modeling the expected deformation of a particular material type and thickness and identifying candidate heating paths that will sufficiently cause the plate to transform towards the target shape.

  • Patent number: 9375151
    Abstract: A method for detecting acute ischemia is disclosed. The method comprises the steps of determining ST segment deviations and storing the results in heart rate based histograms. The histogram data is periodically analyzed to estimate a true range of ST deviation for a particular heart rate range. A current threshold for a heart rate range is set by estimating the true range of ST deviations within that bin, determining the median value of ST deviations within the range, and basing thresholds on the range and median value. The true range for a particular heart rate bin is estimated by locating ST deviation values between which reside a predetermined percentage of all ST deviation values collected for that bin.

  • Publication number: 20160128595
    Abstract: A system for detecting cardiac events and alerting the patient of the cardiac event issued by an implanted medical device. A processor detects a cardiac event and issues an activation signal to a patient alerting mechanism which emits an alarm during a first time interval followed by an alarm-off period of time. Reminder alarms are issued periodically following the alarm-off period of time. Reminder alarms are issued during reminder on-periods of time which are shorter than the first time interval. The alarm-off period and the time between periodic reminder alarms are greater than the alarm first time interval. A disabling device permits disabling of reminder alarms.

  • Patent number: 9192309
    Abstract: A heart monitor is disclosed. The monitor computes ST segment deviations and stores the results in heart rate based histograms. Periodically, the monitor analyzes the histogram data to determine a normal range of ST deviation for a particular heart rate range. The monitor computes heart rate dependent ischemia detection thresholds based on the upper and lower boundaries of the normal range. A current threshold for a heart rate range is set as a weighted average of the prior threshold and a provisional threshold based on recent data, thereby limiting the amount the actual detection threshold changes from period to period.

  • Patent number: 9031644
    Abstract: A heart monitor is disclosed. The monitor computes ST segment deviations and stores the results in heart rate based histograms. Periodically, the monitor analyzes the histogram data to determine heart rate dependent acute ischemia detection thresholds. If the statistical distribution associated with a heart rate range is insufficient, the threshold for that heart rate range is set as a function of the threshold for a neighboring heart rate range. Thresholds are also increased for heart rate ranges associated with statistical distributions that are sufficient but that have a relatively small number of entries.

  • Patent number: 9005130
    Abstract: A method for tracking cardiac conditions is disclosed. An electrical signal from a patient's heart is sensed. A heart signal parameter value and an associated heart rate value are computed from the electrical signal. Based on the heart rate value, one of a plurality of histograms stored in a histogram memory is updated with the heart signal parameter value. After a data collection time period has elapsed, a statistical value of the heart signal parameter is computed from the selected histogram. A detection threshold for abnormal values of the heart signal parameter is then computed based on the statistical value.

  • Patent number: 8965494
    Abstract: Disclosed is a system for the detection of cardiac events that includes an implanted device called a cardiosaver, a physician's programmer and an external alarm system. The system is designed to provide early detection of cardiac events such as acute myocardial infarction or exercise induced myocardial ischemia caused by an increased heart rate or exertion. The system can also alert the patient with a less urgent alarm if a heart arrhythmia is detected. Using different algorithms, the cardiosaver can detect a change in the patient's electrogram that is indicative of a cardiac event within five minutes after it occurs and then automatically warn the patient that the event is occurring. To provide this warning, the system includes an internal alarm sub-system (internal alarm means) within the cardiosaver and/or an external alarm system (external alarm means) which are activated after the ST segment of the electrogram exceeds a preset threshold.

  • Patent number: 8855752
    Abstract: A heart monitor computes ST segment deviation as the difference in the value of an electrocardiogram signal at the ST and PQ points of a heartbeat. The ST point is found based on slope criteria and temporal criteria. The maximum (positive) slope of the QRS (maxQRS) is located. Within a preset window after the maxQRS point, the processor searches for a sample at which the second finite difference is less than a threshold that is a function of average QRS amplitude. If such a qualifying sample is found, the processor examines its location relative to the location of an adaptive window that is centered on a sample that is an adaptively determined distance from the peak of the R wave. If the qualifying point is within the adaptive window, it is chosen as the ST point. If the qualifying point is after the adaptive window, the ST point is set at the end of the adaptive window. Finally, if the qualifying point is before the adaptive window, the ST point is selected at the beginning of the adaptive window.
