  • Patent number: 11413468
    Abstract: Signal analysis in an implanted cardiac monitoring and treatment device such as an implantable cardioverter defibrillator. In some 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 examples 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.

  • Publication number: 20210379364
    Abstract: New methods for implanting a cardiac therapy system include implanting a lead of the system substernally anterior of the heart without attaching to the myocardium or pericardium. An illustration includes placement of an anchor beneath the sternum in the vicinity of one of the sternal angle, a location superior of the ventricles, the area bounded by the 2nd or 3rd ribs, and level with the aortic arch. A tension element or tether is attached to the anchor and a lead is introduced over the tension element or tether and secured in a desired position relative to the anchor. Other examples also include implantation, sub sternally, of a lead without the use of a pre-tunneling tool or sheath over the lead itself, for example by using an advancing tool for pushing the lead into position.

  • Patent number: 11083897
    Abstract: Adaptive methods for initiating charging of the high power capacitors of an implantable medical device for therapy delivery after the patient experiences a non-sustained arrhythmia, and devices that perform such methods. The adaptive methods and devices adjust persistence criteria used to analyze an arrhythmia prior to initiating a charging sequence to deliver therapy. Some embodiments apply a specific sequence of X-out-of-Y criteria, persistence criteria and last even criteria before starting charging for therapy delivery.

  • Patent number: 11020602
    Abstract: The present invention is directed toward a detection architecture for use in implantable cardiac rhythm devices. The detection architecture of the present invention provides methods and devices for discriminating between arrhythmias. Moreover, by exploiting the enhanced specificity in the origin of the identified arrhythmia, the detection architecture can better discriminate between rhythms appropriate for device therapy and those that are not.

  • Patent number: 10974058
    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.

  • Patent number: 10842998
    Abstract: Devices and methods for single therapy pulse (STP) therapy for tacharrythmia are disclosed. The STP therapy can be delivered from a far-field position to allow a “global” capture approach to pacing. Due to the global capture in STP, a series of pulses, which is indicative of conventional anti-tachycardia pacing (ATP) delivered by transvenous systems, becomes unnecessary. One to four pulses at most are needed for STP, and after delivery of the one to four pulses, therapy delivery can be interrupted to determine whether the previously delivered therapy has been successful.

  • Patent number: 10758138
    Abstract: Implantable medical device systems and methods configured to use a detection profile selected from among a plurality of detection profiles to define a detection threshold for identifying cardiac events, in which a close call definition is used to determine which of the plurality of detection profiles is to be chosen. Upon identifying a close call, in which an overdetection nearly occurred but did not actually take place, a relatively less sensitive detection profile is chosen.

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.

  • Patent number: 10617402
    Abstract: Methods and tool kits for implanting a lead subcutaneously. Examples include tool kits and methods for establishing first and second subcutaneous tunnels at an angle relative to one another to facilitate introduction of a lead to the subcutaneous space. In an example, a first insertion tool is used to establish a first subcutaneous tunnel, and a second insertion tool, with or without the use of a blunt dissector, sheath, guidewire, or steering mechanism, is used to initiate or form the second subcutaneous tunnel. Such methods and tool kits may reduce the number of incisions needed to implant a subcutaneous lead along a subcutaneous path having a curve therein.

  • Patent number: 10582870
    Abstract: Methods, systems, and devices for signal analysis in an implantable cardiac device such as an implantable cardioverter defibrillator. In illustrative examples, captured data including detected events is analyzed to identify likely overdetection of cardiac events. Analysis of the apparent width of detected events is used to determine whether overdetection is occurring. If overdetection is identified, data may be modified to correct for overdetection, to reduce the impact of overdetection, or to ignore overdetected data.

  • Patent number: 10575740
    Abstract: Methods and devices for sensing vector analysis in an implantable cardiac stimulus system. In an illustrative example, a first sensing vector is analyzed to determine whether it is suitable, within given threshold conditions, for use in cardiac event detection and analysis. If so, the first vector may be selected for detection and analysis. Otherwise, one or more additional vectors are analyzed. A detailed example illustrates methods for analyzing sensing vectors by the use of a scoring system. Devices adapted to perform these methods are also discussed, including implantable medical devices adapted to perform these methods, and systems comprising implantable medical devices and programmers adapted to communicate with implantable medical devices, the systems also being adapted to perform these methods. Another example includes a programmer configured to perform these methods including certain steps of directing operation of an associated implanted or implantable medical device.
