  • Patent number: 10315889
    Abstract: A lifting device for a motor vehicle subassembly has a load-bearing unit with at least one support arm that can be pivoted around a longitudinal axis of the load-bearing unit and a coupling unit that is arranged on the support arm for releasably connecting the support arm to the motor vehicle subassembly. The coupling unit is mounted on the support arm such that it is longitudinally displaceable, and the load-bearing unit is configured to connect with a crane unit, such as a crane hook adapter. The lifting device is especially compact in construction in that it offers the possibility of being combined with lifting units for the disassembly of motor vehicle subassemblies from the ground. The load-bearing unit is releasably connected with a connecting body of a support unit. The connecting body is tiltable on the support unit.

    Abstract: An implantable medical device having a sensing module and a control module is configured to receive a cardiac electrical signal and sense events from the cardiac electrical signal received via electrodes carried by a medical electrical lead when the medical electrical lead is coupled to the implantable medical device. The control module coupled is configured to detect non-sustained tachyarrhythmia (NST) episodes based on sensed event intervals and determine if the sensed event intervals during the detected NST episode satisfy oversensing criteria. If the oversensing criteria are satisfied, the control module determines whether the detected NST episode satisfies non-lead related oversensing criteria and withholds a lead integrity alert when the NST episode meeting the oversensing criteria is determined to satisfy non-lead related oversensing criteria.

  • Patent number: 10220204
    Abstract: Leakage of signal between conduction paths of an implantable medical lead or lead and lead extension combination is detected. A stimulation signal is provided via one electrode. Two other electrodes sense the stimulation signal. A difference in amplitude of the two sensed signals is determined and based on this difference, leakage is detected. A sensing circuit may use differential amplification of the two signals and compare a resulting output signal to a leakage threshold. When the amplitude of the output signal exceeds the leakage threshold, then leakage is occurring between the conduction path providing the stimulation and one of the conduction paths used for sensing. Other techniques for determining leakage from the difference may also be used such as comparing the amplitudes of the two sensed signals and providing a value that is based on the comparison to indicate whether leakage is present.

Measuring current injecting electrodes (1, 2) are used to force the measuring current flow through the internal part of the analysed bone. At the same time the screening electrodes (7, 8) reduce the measuring current flow through the tissues surrounding the analysed bone almost to zero. Then measuring current and potential at the measuring current injecting electrodes (1, 2) as well as phase difference between potential at measuring current injecting electrodes (1, 2) and measuring current are measured.

  • Patent number: 9713724
    Abstract: In general, the invention is directed to a system with a fail-safe mode for remote programming of medical devices, such as implantable medical devices (IMDs). During a remote programming session, an adverse event, such as a programming session failure, may prevent proper completion of a programming or result in improper programming due to data corruption or other factors. If a programming session is not completed correctly, the IMD is susceptible to improper operation, possibly exposing a patient to delivery of unnecessary or inappropriate therapies. A fail-safe mode reduces the likelihood of improper operation following a programming session failure. The fail-safe mode defines one or more fail-safe operations designed to preserve proper operation of the IMD. In some embodiments, the fail-safe operations include notifying a person concerning the failure of the programming session, modifying programming parameters within the implantable medical device, and delivering a therapy to a patient.

Each second segment and cut-out portion is preferably configured to prevent penetration thereof within tissue at the implant site.

  • Patent number: 9669230
    Abstract: Systems and methods for treating cardiac arrhythmias are disclosed. In one embodiment, an SICD comprises two or more electrodes, a charge storage device, and a controller operatively coupled to two or more of the electrodes and the charge storage device. In some embodiments, the controller is configured to monitor cardiac activity of the heart of the patient, detect an occurrence of a cardiac arrhythmia based on the cardiac activity, and determine a type of the detected cardiac arrhythmia from two or more types of cardiac arrhythmias. If the determined type of cardiac arrhythmia is one of a first set of cardiac arrhythmia types, the controller sends an instruction for reception by an LCP to initiate the application of ATP therapy by the LCP. If the determined type of cardiac arrhythmia is not one of the first set cardiac arrhythmia types, the controller does not send the instruction.

  • Patent number: 9656088
    Abstract: A method and apparatus for determining estimated remaining longevity for an implantable stimulator. A programmer processor is employed to acquire from the implantable stimulator a signal comprising data associated with the power source in the implantable stimulator and a date in which the stimulator was implanted. The programmer processor and the data are used to determine whether a pre-recommended replacement time threshold (pre-RRT) has been attained for replacing the implantable stimulator. The programmer processor is used to select an equation in which to calculate a recommended replacement time (RRT), the equation is selected in response to determining a time period that extends from the date in which the stimulator was implanted until a date in which the pre-RRT is attained.

  • Patent number: 9643011
    Abstract: A patient suffering from congestive heart failure is at increased risk of cardiac arrhythmogenesis during sleep, particularly if experiencing central sleep apnea as a co-morbidity. Low intensity peripheral neurostimulation therapies that target imbalance of the autonomic nervous system have been shown to improve clinical outcomes. Thus, bi-directional autonomic regulation therapy is delivered to the cervical vagus nerve at an intensity that is insufficient to elicit pathological or acute physiological side effects and without the requirement of an enabling physiological feature or triggering physiological marker. The patient's physiology is monitored to identify periods of sleep. In one embodiment, upon sensing a condition indicative of tachyarrhythmia following a period of bradycardia, as naturally occurs during sleep, an enhanced “boost” dose of bi-directional neural stimulation intended to “break” the tachyarrhythmic condition is delivered.

    Abstract: A method and apparatus for determining estimated remaining longevity for an implantable stimulator. The device employs pre-calculated numbers of days for various combinations conditions of device usage parameters to determine remaining device longevity based upon identified actual conditions of device usage and employs the determined longevity to change longevity indicator states in the device. While between longevity state changes, the device the identified conditions of device usage and adjusts the determined longevity if the conditions of use change significantly. The indicator states may correspond to one or more of Recommended Replacement Time (RRT), Elective Replacement Indicator (ERI) or End of Service (EOS).

  • Patent number: 9522277
    Abstract: Techniques for performing a lead integrity test in response to, e.g., during or after saturation of a sensed signal, e.g., a cardiac electrogram (EGM) signal, are described. A lead integrity test may comprise one or more impedance measurements for one or more leads. Possible causes of saturation of a sensed signal include lead conductor or connector issues, or other lead related conditions. A lead integrity test triggered in response to the saturation may be able to detect any lead related condition causing the saturation. A lead integrity test triggered in response to the saturation may advantageously be able to detect an intermittent lead related condition, due to the temporal proximity of the test to the saturation.
