Abstract: Methods and systems for seamless adjustment of treatment are disclosed. A determination can be made as to whether to intervene with a patient's treatment based on data obtained from implantable electrodes and/or non-implantable electrodes. The data from non-implantable electrodes have a correction factor applied to adjust for less accuracy compared to data acquired from implantable electrodes.

Abstract: This disclosure is directed to devices, systems, and techniques for delivering various stimulation patterns. In some examples, a method includes generating, by stimulation generation circuitry, a first train of electrical stimulation pulses at a first frequency to a first target tissue, and generating, by the stimulation generation circuitry, a second train of electrical stimulation pulses at a second frequency to a second target tissue different from the first target tissue, wherein at least some electrical stimulation pulses of the first train of electrical stimulation pulses are interleaved with at least some electrical stimulation pulses of the second train of electrical stimulation pulses, and wherein the first frequency is greater than the second frequency.

Abstract: Processing circuitry for a medical system configured to sense bioelectrical signals and determine posture and activity information as well as information about the environment of the patient. The processing circuitry is also configured to control stimulation generation circuitry to deliver the electrical stimulation therapy, and interleaved with the electrical stimulation therapy, control the stimulation generation circuitry to output an impedance measurement signal. The processing circuitry is further configured to determine respiration of the patient based on the impedance. Responsive to determining the respiration of the patient, the processing circuitry may then determine a patient state based on the determined respiration, and the posture and activity information of the patient. Based on the patient state, the processing circuitry may select an action including one or more of: store collected information, upload the collected information to an external computing device, and output an electronic signal comprising an alert.

Abstract: Processing circuitry of a system configured to determine a patient state based on sensed signals including posture and activity information and control delivery of electrical stimulation therapy to the patient via electrodes implanted proximal to target tissue of the patient. The sensed signals also include impedance measurement, and other bioelectrical signals, where sensing is interleaved with the electrical stimulation therapy. Responsive to determining the patient state, select an action, wherein the selected action comprises one or more of: store collected information, upload the collected information to an external computing device, and output an electronic signal comprising an alert.

Abstract: Some aspects relate to systems, devices, and methods of delivering rate responsive pacing therapy. The method includes monitoring activity information related to an activity level of a patient and delivering rate responsive pacing (RRP) to the patient at a pacing rate corresponding to a RRP profile. The RRP profile may be used to generate the pacing rate based on the activity information and may be adjusted based on the monitored activity information.

Abstract: Techniques are disclosed for using a cardiac signal sensed via a plurality of electrodes disposed on one or more leads implanted within an epidural space of a patient to control spinal cord stimulation (SCS) therapy. In one example, an implantable medical device (IMD) senses an electrical signal via a plurality of electrodes disposed on one or more leads implanted within an epidural space of a patient. Processing circuitry determines, from the electrical signal, one or more cardiac features indicative of activity of a heart of the patient. The processing circuitry controls, based on the one or more cardiac features, delivery of SCS therapy to the patient.

Abstract: A medical device is configured to produce an accelerometer signal and detect a patient fall from the accelerometer signal. The device generates a body posture signal and a body acceleration signal from the accelerometer signal and detects a patient fall in response to determining that the body posture signal and the body acceleration signal meet fall detection criteria. The medical device is configured to receive a truth signal from another device that is not the medical device. The truth signal may indicate that the detected patient fall is a falsely detected patient fall and, responsive to receiving the truth signal, the medical device adjusts at least one fall detection control parameter.

Abstract: A method for heart failure management may include volume overload intervention in response to sensor-based parameters indicating volume overload. The method may include administering non-volume overload intervention in response to the sensor-based parameters not indicating volume overload. Volume overload may be determined based on monitoring sensor-based parameters. Sensor-based parameters may be monitored in response to receiving an alert indicative of a worsening heart failure score or status for a patient.

Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.

Abstract: Techniques are disclosed for automatically calibrating a reference orientation of an implantable medical device (IMD) within a patient. In one example, sensors of an IMD sense a plurality of orientation vectors of the IMD with respect to a gravitational field. Processing circuitry of the IMD processes the plurality of orientation vectors to identify an upright vector that corresponds to an upright posture of the patient. The processing circuitry classifies the plurality of orientation vectors with respect to the upright vector to define a sagittal plane of the patient and a transverse plane of the patient. The processing circuitry determines, based on the upright vector, the sagittal plane, and the transverse plane, a reference orientation of the IMD within the patient. As the orientation of the IMD within the patient changes over time, the processing circuitry may recalibrate its reference orientation and accurately detect a posture of the patient.
