摘要： The disclosure describes examples of antennas used for communication with an implantable medical device (IMD). As one example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing, and a planar antenna, having a curved structure, that is stacked on an external side of the housing and coupled to the communication circuitry. As another example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing and an antenna having a curved structure formed on an external side of the housing and coupled to the communication circuitry. A resonant frequency of the antenna is based on a dielectric constant of tissue surrounding the antenna when the IMD is implanted, and a current distribution of the antenna is in-phase in opposite sides of the antenna.

摘要： In some examples, a coil electrode assembly includes a coil electrode including a plurality of windings and extending from an electrode proximal end to an electrode distal end, the coil electrode defining an electrode lumen from the electrode proximal end to the electrode distal end. The coil electrode assembly further includes an insulative tube extending within the lumen of the coil electrode such that the coil electrode extends along an outer surface of the insulative tube. The coil electrode is partially embedded within the insulative tube when the insulative tube is in an expanded state to maintain a spacing between the windings.

摘要： Techniques are described for discriminating SVT and, in particular, rapidly conducting AF. The techniques include detecting an onset of a fast rate of ventricular events sensed from a cardiac electrical signal and detecting a pause in the fast rate of ventricular sensed events. A threshold number of ventricular event intervals required to detect a ventricular tachyarrhythmia is detected with each of the threshold number of ventricular event intervals being less than a tachyarrhythmia detection interval. Detection of the ventricular tachyarrhythmia and an electrical stimulation therapy for treating the ventricular tachyarrhythmia are withheld in response to at least the pause being detected.

摘要： A medical device, such as an extra-cardiovascular implantable cardioverter defibrillator (ICD), senses R-waves from a first cardiac electrical signal by a first sensing channel and stores a time segment of a second cardiac electrical signal acquired by a second sensing channel in response to each sensed R-wave. The ICD determines morphology match scores from the stored time segments of the second cardiac electrical signal and, based on the morphology match scores, withholds detection of a tachyarrhythmia episode. In some examples, the ICD detects T-wave oversensing based on the morphology match scores and withholds detection of a tachyarrhythmia episode in response to detecting the T-wave oversensing.

摘要： A cardiac medical system, such as an implantable cardioverter defibrillator (ICD) system, receives a cardiac electrical signal by and senses cardiac events when the signal crosses an R-wave sensing threshold. The system determines at least one sensed event parameter from the cardiac electrical signal for consecutive cardiac events sensed by the sensing circuit and compares the sensed event parameters to P-wave oversensing criteria. The system detects P-wave oversensing in response to the sensed event parameters meeting the P-wave oversensing criteria; and adjusts at least one of an R-wave sensing control parameter or a therapy delivery control parameter in response to detecting the P-wave oversensing.

摘要： A system for retrieving an implanted medical device includes an outer tubular member and a contractible super-elastic net, which may be joined to an elongate shaft that extends in sliding engagement within the outer tubular member. When the net expands from a contracted condition the net defines a longitudinally extending tubular cavity. An open end of the cavity is sized to receive passage of a housing of the device therethrough; and the net, with the device housing contained therein, forms an interference fit within an inner diameter of the outer tubular member. But, an outer diameter of the net, in a fully expanded condition, is larger than the inner diameter.

摘要： Implantable medical devices automatically switch from a normal mode of operation to an exposure mode of operation and back to the normal mode of operation. The implantable medical devices may utilize hysteresis timers in order to determine if entry and/or exit criteria for the exposure mode are met. The implantable medical devices may utilize additional considerations for entry to the exposure mode such as a confirmation counter or a moving buffer of sensor values. The implantable medical devices may utilize additional considerations for exiting the exposure mode of operation and returning to the normal mode, such as total time in the exposure mode, patient position, and high voltage source charge time in the case of devices with defibrillation capabilities.

摘要： In some examples, an implantable medical device determines that another medical device delivered an anti-tachyarrhythmia shock, and delivers post-shock pacing in response to the determination. The implantable medical device may be configured to both detect the delivery of the shock in a sensed electrical signal and, if delivery of the shock is not detected, determine that the shock was delivered based on detection of asystole of the heart. The asystole may be detected based on the sensed electrical signal. In some examples, an implantable medical device is configured to revert from a post-shock pacing mode to a baseline pacing mode by iteratively testing a plurality of decreasing values of pacing pulse magnitude until loss of capture is detected. The implantable medical device may update a baseline value of the pacing pulse magnitude for the baseline mode based on the detection of loss of capture.
