  • Patent number: 10716482
    Abstract: Catheter systems and methods for determining blood flow rates based on temperature measurements by thermodilution. The catheter may include a fluid lumen defined between inner and outer tubular members for delivering an indicator fluid, and a guidewire lumen defined by the inner tubular member. The catheter may include fluid infusion openings at the distal end region of the outer tubular member configured to permit the indicator fluid to exit the catheter from the fluid lumen, and a fluid hole located at the distal end region of the inner tubular member configured to permit the indicator fluid to pass from the fluid lumen into the guidewire lumen. A temperature sensor positioned on a guidewire may be positioned within the guidewire lumen to measure the temperature of the indicator fluid entering the guidewire lumen through the fluid hole.

  • Patent number: 10709392
    Abstract: Analyte sensor faults are detected. Datasets of glucose values sensor electronics are coupled to a glucose sensor in fluid contact with interstitial fluid under a skin surface. Baseline median glucose value and glucose variability values are computed, based on the first dataset. A baseline data point is stored. Evaluation median glucose value and variability are computed, based on the second dataset of glucose values. An evaluation data point is stored. A magnitude of a vector that extends between the baseline data point and the evaluation data point is computed. A component of the magnitude of the vector that is parallel to a hypoglycemia risk contour line is computed and compared to a predefined threshold value. An indication that a sensor fault has been detected if the component is greater than a threshold is displayed.

  • Patent number: 10682083
    Abstract: A sensor system comprises first and second PPG sensors. A monitoring system monitors detection by at least one of the first and second detectors an optical calibration signals, for performing time calibration between the first and second PPG sensors. This system makes use of two PPG sensors. To enable these sensors to be independent units, rather than being fully integrated into a combined system, a calibration system is provided. Based on detected optical signals, the behavior over time of each PPG sensor can be monitored and thus calibration can take place.

  • Patent number: 10660550
    Abstract: Implantable sensor apparatus and methods of implantation. In one embodiment, a fully implantable, biocompatible sensor is disposed within a cavity or pocket formed within a living being, such that the sensor remains in a desired orientation and placement so as to enhance the performance of the sensor, and mitigate the effects of one or more factors potentially deleterious to the operation of the sensor and the host being. In one implementation, the sensor comprises an implantable biocompatible oxygen-based glucose sensor which is implanted deep within the being's torso tissue proximate the extant fascia, and oriented such that an active detector aspect of the device faces away from the being's skin surface. In one variant, the deep placement, orientation, and construction of the sensor itself cooperate to enhance the performance of the sensor, especially over extended periods of time, with little need for external calibration.
