  • Patent number: 10092227
    Abstract: A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a ‘fiducial’ marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.

  • Patent number: 10027447
    Abstract: Circuits are used to sense and compensate or mitigate the imbalance errors, hence restoring the intended benefits of differential processing. In particular, the impedance mismatch between the positive and negative branches of a balanced system is sensed by digitizing an error voltage developed by injecting suitable common mode stimuli. The mismatch is then trimmed out by introducing and properly setting up a digitally controlled impedance that counters the original impedance mismatch and hence rebalances the signal path on-situ and prior to exercising the signal processing chain.

    Abstract: Techniques are provided for use with an implantable medical device for assessing stroke volume or related cardiac function parameters such as cardiac output based on impedance signals obtained using hybrid impedance configurations that exploit a multi-pole cardiac pacing/sensing lead implanted near the left ventricle. In one example, current is injected between a large and stable reference electrode and a ring electrode in the RV. The reference electrode may be, e.g., a coil electrode implanted within the superior vena cava (SVC). Impedance values are measured along a set of different sensing vectors between the reference electrode and each of the electrodes of the multi-pole LV lead. Stroke volume is then estimated and tracked within the patient using the impedance values. In this manner, a hybrid impedance detection configuration is exploited whereby one vector is used to inject current and other vectors are used to measure impedance.

  • Patent number: 9916421
    Abstract: The description relates to surgical computer systems, including computer program products, and methods for implant planning using corrected captured joint motion information. Data representative of a corrected limb pose at a plurality of poses within a range of motion of a joint associated with a particular individual is captured, the joint comprising a first bone and a second bone, while the first bone, the second bone, or both are subject to a corrective force aligning the first and second bones in a desired alignment. The first bone of the joint is represented. The second bone of the joint is represented. A first implant model is associated with the representation of the first bone. A second implant model is associated with the representation of the second bone. Based on the captured data, a relationship is determined between the first implant model and the second implant model at one or more poses of the plurality of poses within the range of motion of the joint.

  • Patent number: 9913612
    Abstract: The invention provides a sensor for measuring both impedance and ECG waveforms that is configured to be worn around a patient's neck. The sensor features 1) an ECG system that includes an analog ECG circuit, in electrical contact with at least two ECG electrodes, that generates an analog ECG waveform; and 2) an impedance system that includes an analog impedance circuit, in electrical contact with at least two (and typically four) impedance electrodes, that generates an analog impedance waveform. Also included in the neck-worn system are a digital processing system featuring a microprocessor, and an analog-to-digital converter. During a measurement, the digital processing system receives and processes the analog ECG and impedance waveforms to measure physiological information from the patient. Finally, a cable that drapes around the patient's neck connects the ECG system, impedance system, and digital processing system.

  • Patent number: 9907514
    Abstract: Described is an infant monitoring and alerting system capable of determining an absence of movement by an infant. When an absence of movement is detected the monitor attempts to stimulate movement using stimuli that may include a vibration, an audible alert, or a visual alert. If no movement is detected in response to the stimuli, the monitor may provide another instance of stimuli which may include stimuli at an elevated intensity or additional and/or different stimuli. The additional instance of stimuli may further attempt to stimulate movement by the infant and may also function as an alert to the caregiver that their attention may be required.
