    Abstract: Medical systems and methods for making and using medical systems are disclosed. An example may include a catheter, a sensor, and a pump configured to remove contrast from a vascular system. The catheter may have a lumen through which the pump may suction contrast. The sensor may be positioned distal of and upstream of a distal end of the aspiration lumen and the pump may initiate suction through the lumen in response to a value sensed by the sensor reaching and/or going beyond a threshold value. The catheter may include an expandable member configured to expand in response to a value sensed by the sensor reaching and/or going beyond a threshold value. The sensor may be supported by a distal extension of the catheter or an elongate member configured to extend through and/or along the catheter to position the sensor distal of the distal end of the aspiration lumen.

  • Publication number: 20180207426
    Abstract: Methods and devices for configuring the use of a motion sensor in an implantable cardiac device. The electrical signals of the patient's heart are observed and may be correlated to the physical motion of the heart as detected by the motion sensor of the implantable cardiac device in order to facilitate temporal configuration of motion sensor data collection that avoids detecting cardiac motion in favor of overall motion of the patient.

  • Patent number: 9968787
    Abstract: Implantable devices having motion sensors. In some examples the a configuration is generated for the implantable device to use the motion sensor in an energy preserving mode in which one or more axis of detection of the motion sensor is disabled or ignored. In some examples the motion sensor outputs along multiple axes are analyzed to determine which axes best correspond to certain patient parameters including patient motion/activity and/or cardiac contractility. In other examples the output of the motion sensor is observed across patient movements or postures to develop conversion parameters to determine a patient standard frame of reference relative to outputs of the motion sensor of an implanted device.

  • Publication number: 20170347969
    Abstract: Systems and methods for monitoring patients with respiratory diseases are described. A system may include a sensor circuit to sense a respiration signal and at least one hemodynamic signal. The system may detect a specified respiratory phase from the respiration signal, and generate from the hemodynamic signal one or more signal metrics that are correlative to at least one of a systolic blood pressure, a blood volume, or a cardiac dimension. The system may detect a restrictive or obstructive respiratory condition when the hemodynamic signal metric indicates hemodynamic deterioration during a specified respiratory phase. The system may additionally classify the detected restrictive or obstructive respiratory condition into one of two or more categories, and deliver a therapy based on the detection or the classification.
