Various electronic components of the present invention may be encapsulated with a potting material.

An apparatus for insertion of a medical device in the skin of a subject is provided in one embodiment, a sensor is provided comprising a body having a proximal section, a distal section longitudinally aligned with the proximal section, and an intermediate section, wherein the intermediate section is laterally displaced from at least the distal member and a gap is defined between the laterally displaced intermediate section and a portion of the distal section.

Systems, devices and methods are provided for the monitoring and management of an individual's wellness and nutrition using analyte data from an in vivo analyte sensor. Generally, a sensor control device is provided for wear on the body. The sensor control device can include an in vivo analyte sensor for measuring an analyte level in a bodily fluid, an accelerometer for measuring the physical activity level of the subject, as well as communications circuitry for wirelessly transmitting data to a reader device. Furthermore, disclosed herein are embodiments of various graphical user interfaces for displaying analyte metrics on a reader device, comparing the analyte response of various foods and/or meals, modifying daily nutrient recommendations based on analyte metrics and physical activity level measurements, and other features described herein. Additionally, the embodiments disclosed herein can be used to monitor various types of analytes.

Systems, devices, and methods are provided for changing the power state of a sensor control device in an in vivo analyte monitoring system in various manners, such as through the use of external stimuli (light, magnetics) and RF transmissions.

Bovine milk-isolated powdered exosomes comprise intact exosomes. Nutritional compositions comprise protein, carbohydrate, and/or fat, and exosomes isolated from bovine milk. A method of preparing powdered exosomes comprises centrifuging bovine milk to form a lipid fraction top layer, a whey fraction middle layer, and a first pellet of cells and debris, separating the whey fraction and centrifuging the separated whey fraction to remove additional fat, casein aggregates and debris and form a substantially clear whey fraction, microfiltering the substantially clear whey fraction to remove residual debris, centrifuging the microfiltered whey fraction to obtain a pellet containing exosomes, incubating the exosomecontaining pellet in aqueous medium to dissolve the pellet without disrupting exosome membranes to provide an exosome suspension, and drying the suspension to obtain the powdered exosomes. Methods of lowering a risk of developing, or treating, insulin resistance, prediabetes, or diabetes in a subject employ exosomes isolated from bovine milk.

A system, apparatus, or device that includes an analyte sensor for monitoring analyte levels. The system, apparatus, or device can include a printed circuit board configured to monitor an analyte level, and a battery connected to the printed circuit board and configured to power the printed circuit board. The system, apparatus, or device can also include a connector connected to the printed circuit board and configured to establish an electrical connection between and analyte sensor and the printed circuit board, and a processor connected to the printed circuit board and configured to process data associated with the monitored analyte level. In addition, the system, apparatus, or device, can include an antenna for transmitting the monitored analyte level resting on a plurality of risers. The risers can extend from a surface of the printed circuit board by a fixed distance.

Devices associated with on-body analyte sensor units are disclosed. These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together.

A sensor carrier for use in an applicator for delivering a sensor control device, the sensor carrier comprising a base having a first half and a second half; a first sensor retention arm coupled to the first half of the base at a first end portion of the first sensor retention arm and having a free second end portion extending toward the second half of the base, the first sensor retention arm including a first sensor retention feature on an inner surface of the first sensor retention arm and a first lock interface on an outer surface of the first sensor retention arm; and a second sensor retention arm coupled to the first half of the base at a first end portion of the second sensor retention arm and having a free second end portion extending toward the second half of the base, the second sensor retention arm including a second sensor retention feature on an inner surface of the second sensor retention arm and a second lock interface on an outer surface of the second sensor retention arm.

Multiple enzymes may be present in the active area(s) of an electrochemical sensor to facilitate analysis of analytes. The multiple enzymes may function independently to detect several analytes or in concert to detect a single analyte. One configuration includes a first active area and a second active area, where the first active area has an oxidation-reduction potential that is sufficiently separated from the oxidation-reduction potential of the second active area to allow independent signal production. Some configurations may have an active area overcoated with a multi-component membrane containing two or more different membrane polymers. Sensor configurations having multiple enzymes capable of interacting in concert include those in which a first enzyme converts an analyte into a first product and a second enzyme converts the first product into a second product, thereby generating a signal at a working electrode that is proportional to the analyte concentration.

Digital and graphical user interfaces for third party analyte monitoring applications are provided. For example, disclosed herein are various embodiments of methods, systems, and interfaces for connection interfaces, alarm notification settings interfaces, and logbook interfaces in a third party analyte monitoring application. In addition, various embodiments of interface enhancements are described, including enhanced visibility mode and interfaces for setting up a third party analyte monitoring application, among other embodiments.
