An insertion set system includes a base configured to be secured to a patient, and a flexible tubing on the base. The flexible tubing has a distal end portion forming a cannula to be inserted into the patient. An inserter having a needle is received by the base. The needle has a channel in which the distal end portion of the flexible tubing is received. The needle is able to slide relative to the flexible tubing, to selectively withdraw the needle off of the distal end portion of the flexible tubing. The base may include a passage for fluid flow arranged transverse to the axial dimension of the distal end portion of the flexible tubing.

Flexible cannula insertion device, system and process

A fluid infusion system includes a housing configured to be adhesively coupled to an anatomy of a user, and a tube configured to extend from the housing for insertion into the anatomy of the user. The tube includes a plurality of conduits defined within the tube. The plurality of conduits include a fluid delivery conduit configured to facilitate a fluidic connection between a fluid source and the anatomy of the user, and one or more conduits configured to accommodate a plurality of electrodes for determining a physiological characteristic of the user.

Fluid infusion systems

A fluid infusion system includes a housing configured to be adhesively coupled to an anatomy of the user. The housing comprises a communication device configured to wirelessly communicate a physiological characteristic to a communication component of a fluid infusion device. The fluid infusion system includes a fluid flow path from the fluid infusion device into the anatomy of the user, and the fluid flow path is configured to extend from the housing for insertion into the anatomy of the user.

Disclosed is a medical device component for delivering medication fluid to a patient. The medical device component includes a fluid infusion device to regulate delivery of medication fluid, a body-mountable base unit, and a top cover assembly that is removably couplable to the base unit and to the fluid infusion device. The base unit includes a cannula to deliver medication fluid under the control of the fluid infusion device, and a physiological analyte sensor to measure a physiological characteristic. The base unit also includes an electronics assembly electrically connected to sensor leads to obtain measurements in the analog domain, to convert measurements into digital sensor data, and to communicate conditioned digital sensor data to the fluid infusion device. The top cover assembly is configured to provide both fluid and electrical connections for the base unit, by way of an infusion tube having sensor conductors integrated therein or otherwise associated therewith.

Medication fluid infusion set component with integrated physiological analyte sensor, and corresponding fluid infusion device

Medical devices and related augmented reality systems and methods are provided. A method of operating an infusion device involves analyzing one or more images captured by an imaging device to identify image content indicative of an activity capable of influencing the physiological condition of the patient and in response to identifying the activity based at least in part on the one or more images, automatically adjusting delivery of the fluid to the patient based at least in part on the activity. An expected nutritional characteristic for a meal is determined based at least in part on the image content, and a delivery adjustment for delivering the fluid is determined based on the expected nutritional characteristic. A graphical indication of the delivery adjustment may also be provided using augmented reality.

Proactive image-based infusion device delivery adjustments

Medical devices and related augmented reality systems and methods are provided. A method of providing guidance to a patient using an electronic device having an imaging device associated therewith involves analyzing one or more images captured by the imaging device to identify image content indicative of a potential activity for the patient, determining, by a control system associated with the electronic device, one or more attributes for the potential activity, determining, by the control system, a predicted physiological response by the patient to the potential activity based at least in part on the one or more attributes, and providing, on a display associated with the electronic device, an augmented reality graphical user interface including a graphical indication influenced by the predicted physiological response.

Proactive patient guidance using augmented reality

A flexible, fluid flow tubing is configured to be kink resistant, and a medical device is configured with such kink resistant tubing. The tubing has a length L and a circular cross-section shape taken perpendicular to the length dimension. The tubing has an inside radius r and an outside radius R, wherein L/R&#x2265;34.8, and wherein R/r&#x2265;1.5. The tubing may be made of a polyether block amide (PEBA) or other thermoplastic elastomer (TPE). The tubing may be received in a channel of a hollow needle, wherein the needle is slideable in the axial dimension relative to the tubing, to selectively slide off of at least a portion of the tubing.

Embodiments of the invention provide analyte sensors having optimized elements and/or configurations of elements as well as methods for making and using such sensors. Typical embodiments of the invention include glucose sensors used in the management of diabetes.

Analyte sensor apparatuses having improved electrode configurations and methods for making and using them

Disclosed are methods, apparatuses, etc. for glucose sensor signal stability analysis. In certain example embodiments, a series of samples of at least one sensor signal that is responsive to a blood glucose level of a patient may be obtained. Based at least partly on the series of samples, at least one metric may be determined to assess an underlying trend of a change in responsiveness of the at least one sensor signal to the blood glucose level of the patient over time. A reliability of the at least one sensor signal to respond to the blood glucose level of the patient may be assessed based at least partly on the at least one metric assessing the underlying trend. Other example embodiments are disclosed herein.

Glucose sensor signal stability analysis

A method is provided for initializing an analyte sensor, such as a glucose sensor. Where a sensor has been disconnected and reconnected, a disconnection time is determined and a sensor initialization protocol is selected based upon the disconnection time. The sensor initialization protocol may include applying a first series of voltage pulses to the sensor. A method for detecting hydration of a sensor is also provided.

Methods and systems for optimizing sensor function by the application of voltage

Embodiments of the invention provide amperometric analyte sensors having multiple related structural elements (e.g. sensor arrays comprising a working, counter and reference electrode) and algorithms designed for use with such sensors. While embodiments of the innovation can be used in a variety of contexts, typical embodiments of the invention include glucose sensors used in the management of diabetes.
