  • Patent number: 10661085
    Abstract: Methods and devices are provided for managing anti-tachycardia pacing therapy delivered by an implantable medical device (IMD). The methods and devices detect events from cardiac signals sensed at electrodes of the IMD. The cardiac signals represent a ventricular tachycardia (VT) episode that includes at least a select number of VT events having a corresponding VT cycle length. The methods and devices analyze the VT cycle length to define an anti-tachycardia pacing (ATP) therapy that includes a first coupling interval and deliver a first ATP pulse that is spaced the first coupling interval after a reference refractory VT event sensed at the electrodes. The methods and devices deliver a second ATP pulse following the first ATP pulse by a non-stimulation segment that is at least one and three-quarters (1.75) times a projected VT cycle length.

  • Publication number: 20200161750
    Abstract: Disclosed herein is an implantable electronic device including a housing containing an electrical circuit. The implantable electronic device further includes an antenna assembly coupled to the electrical circuit. The antenna assembly includes an antenna including a dielectric antenna body within which an antenna trace is disposed. Portions of the antenna trace are disposed in offset transverse layers in a non-overlapping arrangement, thereby reducing capacitive coupling between the layers of the antenna trace. In certain implementations, the antenna assembly includes one or more capacitive features that selectively overlap portions of the antenna trace and facilitate tuning of the antenna.

  • Patent number: 10653859
    Abstract: Disclosed herein is a delivery catheter for implanting a leadless biostimulator. The delivery catheter includes a shaft and a tubular body having a lumen and an atraumatic end. The atraumatic end includes at least one of a braided, woven or mesh construction configured to facilitate the atraumatic end changing diameter. When a distal portion of the shaft is coupled to a proximal region of the leadless biostimulator, at least one of distally displacing the tubular body relative to the shaft or proximally displacing the shaft relative to the tubular body causes the leadless biostimulator to be received in the volume of the atraumatic end and the atraumatic end to encompass the leadless biostimulator. Conversely, at least one of proximally displacing the tubular body relative to the shaft or distally displacing the shaft relative to the tubular body causes the leadless biostimulator to exit the volume of the atraumatic end.

  • Patent number: 10639482
    Abstract: A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.

  • Publication number: 20200129082
    Abstract: Devices and methods for dynamically controlling sensitivity associated with detecting R-waves while maintaining the fixed detection threshold are described herein. One such method includes sensing an analog signal indicative of cardiac electrical activity, converting the analog signal indicative of cardiac electrical activity to a digital signal indicative of cardiac electrical activity, and detecting R-waves by comparing the digital signal indicative of cardiac electrical activity to a fixed detection threshold to thereby detect threshold crossings that corresponds to R-waves. The method further includes selectively adjusting a gain applied to the digital signal indicative of cardiac electrical activity to thereby selectively adjust a sensitivity associated with the detecting R-waves, while maintaining the fixed detection threshold.

  • Patent number: 10632315
    Abstract: Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes enabling a communication capability of an IMD during a message alert period and monitoring for a message while the communication capability is enabled during the message alert period. In response to receiving a message during the message alert period, there is a determination whether the message is valid or invalid. If the message is invalid, the message is ignored, and an invalid message count is incremented. A further message is monitored for during the message alert period occurs, when the invalid message count has not yet reached a corresponding invalid message count threshold. The communication capability of the IMD is disabled for a disable period, when the invalid message count reaches the corresponding invalid message count threshold. If a valid message is received, the IMD acts upon information included therein.

  • Patent number: 10625079
    Abstract: Methods and systems are provided for managing residual charge for multi-point pacing therapy. The method and system provide an electrode configuration that includes an atrial (A) electrode, a right ventricular (RV) electrode and multiple left ventricular (LV) electrodes. The method and system deliver pacing pulses for an MPP therapy, during a first cardiac cycle, from a pulse generator to the electrode configurations. The pacing pulses are separated by pacing pulse (PP) intervals. The method and system dynamically adjust at least one of a timing or a duration of discharge pulses for the residual charge to form a discharge sequence. The method and system activate the discharge pulses based on the discharge sequence, during the first cardiac cycle, to the multiple LV electrodes to distribute the residual charge across the PP intervals.

  • Patent number: 10610690
    Abstract: A fully implantable trial neurostimulation system for implant within a patient is provided that includes one or more leads equipped to deliver neurostimulation to patient tissues under the control of a trial neurostimulation control device designed as a capsule for removable implant within the patient. The control capsule is provided with minimal components to power and control the delivery of neurostimulation during a trial evaluation period and is shaped and configured to facilitate removal from the patient following completion of the trial period. In some examples, both the lead and the trial control capsule are removed from the patient following the trial period for replacement with a chronic or long-term neurostimulation system (assuming further neurostimulation is warranted.) In other examples, the lead remains within the patient and the trial control capsule is replaced with a long-term neurostimulation controller device. Various minimally-intrusive implantation procedures are also described.
