Abstract: Fluid injection devices and related systems and operating methods are provided. An exemplary injection device includes an actuation arrangement to facilitate delivering fluid from a container, a user interface element coupled to the actuation arrangement, a data storage element to maintain one or more patient-specific parameter values and historical bolus data, and a control module coupled to the actuation arrangement and the data storage element. The control module of the injection device determines a bolus amount of the fluid to be delivered based at least in part on the one or more patient-specific parameter values and the historical bolus data in response to receiving a user input indicative of a desire to administer a bolus, and the control module configures the actuation arrangement to automatically deliver the bolus amount in response to manual actuation of the user interface element.
Abstract: A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.

Abstract: The invention disclosed herein includes electrode compositions formed from processes that sputter metal in a manner that produces pillar architectures. Embodiments of the invention can be used in analyte sensors having such electrode architectures as well as methods for making and using these sensor electrodes. A number of working embodiments of the invention are shown to be useful in amperometric glucose sensors worn by diabetic individuals. However, the metal pillar structures have wide ranging applicability and should increase surface area and decrease charge density for catalyst layers or electrodes used with sensing, power generation, recording, and stimulation, in vitro and/or in the body, or outside the body.

Abstract: An insulin infusion device and related operating methods are disclosed. An operating method maintains a configurable, patient-specific, target glucose setpoint for a user of the insulin infusion device, collects historical data associated with operation of the insulin infusion device, and calculates, from the historical data, a target glucose setpoint profile for the user of the insulin infusion device. A current target glucose setpoint value is automatically adjusted over time during a closed-loop operating mode of the insulin infusion device, in accordance with the calculated target glucose setpoint profile. In certain embodiments, the historical data is analyzed to determine a clinically preferred target glucose setpoint value for the user, which is stored for use during the closed-loop operating mode.

Abstract: A sensing device monitors and tracks food intake events and details. A processor, appropriately programmed, controls aspects of the sensing device to capture data, store data, analyze data and provide suitable feedback related to food intake. More generally, the methods might include detecting, identifying, analyzing, quantifying, tracking, processing and/or influencing, related to the intake of food, eating habits, eating patterns, and/or triggers for food intake events, eating habits, or eating patterns. Feedback might be targeted for influencing the intake of food, eating habits, or eating patterns, and/or triggers for those. The sensing device can also be used to track and provide feedback beyond food-related behaviors and more generally track behavior events, detect behavior event triggers and behavior event patterns and provide suitable feedback.
