A continuous analyte monitor wearable device. The wearable device includes a primary portion comprising at least a sensor assembly comprising a biosensor, and a secondary portion comprising a pocket configured to receive a transmitter unit and a sealable opening to the pocket, the sealable opening containing an adhesive on edges thereof; and a backing member provided over the adhesive wherein removing the backing member exposes the adhesive to seal the sealable opening and encapsulate the transmitter unit. Biosensor inserters and method of using the biosensor inserter are also provided.

A base unit of a wearable device for continuous analyte monitoring includes a cup configured to receive a power source. A first power source contact is at least partially located in the cup and configured to electrically contact a first terminal of the power source in response to the power source being received in the cup. At least one base contact is electrically coupled to the first power source contact, the at least one base contact configured to electrically contact at least one transmitter contact of a transmitter unit in response to the transmitter unit and the base unit being coupled together. Numerous other embodiments are provided.

A biosensor inserter is configured to insert a biosensor. The biosensor inserter includes a push member including a receiver, a contact member translatable relative to the push member, and a trocar holder having a sheath configured to receive a trocar assembly including a trocar therein. The trocar holder is configured to be insertable into, and removable from, the receiver. Thus, an amount of medical waste can be minimized by discarding only the removable trocar holder and trocar assembly after use. System and method embodiments are provided.

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.

The present embodiments relate generally to applicators of on-skin sensor assemblies for measuring an analyte in a host, as well as their method of use and manufacture. In some aspects, an applicator for applying an on-skin sensor assembly to a skin of a host is provided. The applicator includes an applicator housing, a needle carrier assembly comprising an insertion element configured to insert a sensor of the on-skin sensor assembly into the skin of the host, a holder releasably coupled to the needle carrier assembly and configured to guide the on-skin sensor assembly while coupled to the needle carrier assembly, and a drive assembly configured to drive the insertion element from a proximal starting position to a distal insertion position, and from the distal insertion position to a proximal retraction position.

Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

A diversified glucose sensor system comprises an introducer needle and two or more independent sensor bodies, each sensor body having one or more sensing elements that can be subcutaneously positioned in a patient's body by insertion of the introducer needle for glucose measurement. The system further includes a progressive insertion device comprising an insertion shaft that pushes the sensor bodies out the end opening of the introducer needle to a desired depth in the patient prior to removal of the insertion shaft and the introducer needle. The sensor bodies are bent or folded and held under stress within the introducer needle for insertion, and released and biased outwardly when pushed out of the introducer needle. The sensing elements are anchored and disposed within the patient at positions providing X/Y/Z-axis diversity for measurement.

An apparatus for insertion of a medical device in the skin of a subject is provided.

Systems for applying a transcutaneous monitor to a person can include a telescoping assembly, a sensor, and a base with adhesive to couple the sensor to skin. The sensor can be located within the telescoping assembly while the base protrudes from a distal end of the system. The system can be configured to couple the sensor to the base by compressing the telescoping assembly.

A sensor assembly (256) for detecting at least one analyte in a body fluid and a method of assembly a sensor assembly (256) for detecting at least one analyte in a body fluid are disclosed. The sensor assembly (256) comprises: at least one body mount (212) configured for attachment to a body of a user; at least one electronics unit (186) attachable to the body mount (212), having at least one electronics component (208) for one or more of controlling the detection of the analyte or transmitting measurement data to another component;
wherein the body mount (212) includes a locking mechanism (216) having at least one lever (218) pivotably mounted to the body mount (212), the lever (218) being configured to lock the electronics unit (186) to the body mount (212).
