A coupling tool for coupling together an electronics unit and a base unit of a wearable device for continuous analyte monitoring includes a carrier comprising a receiving feature and a carrier retention device, the carrier retention device configured to retain an electronics unit adjacent the receiving feature. The coupling tool also includes an activator including: a first member at least partially receivable in the receiving feature and a contact member configured to release the electronics unit from the carrier retention device in response to movement of the activator relative to the carrier. The coupling tool is in a locked configuration when the carrier retention device is configured to retain the electronics unit, and the coupling tool is in an unlocked configuration when the carrier retention device is configured to release the electronics unit from the carrier retention device. Other embodiments and methods are also disclosed.

Methods and apparatus enabling coupling of an electronics unit to a base unit of a continuous analyte monitoring device

In one or more embodiments, a continuous analyte monitoring wearable device includes a disposable base unit having a power source and an analyte sensor, and a reusable transmitter unit that includes electronic circuitry configured to bias the analyte sensor, measure current through the analyte sensor, and may even compute analyte values based on measured current through the analyte sensor. The disposable base unit is configured to couple to the reusable transmitter unit and supply electrical power to the electronic circuitry of the reusable transmitter unit for continuous analyte monitoring. Numerous other embodiments are provided.

Sterilized reusable wearable devices and wearable device forming methods in continuous analyte monitoring

A wearable continuous analyte monitoring (CAM) device includes a disposable sensor unit and a long-life reusable transmitter unit. The transmitter unit has no power source and has an enclosure that seals wireless transmitter circuitry within. The disposable sensor unit is configured to receive and provide power to the transmitter unit therein. Upon expiration of the disposable sensor unit, the transmitter unit can be removed from the disposable sensor unit and reused in another disposable sensor unit with a fresh power source. The CAM device has a cover constructed of a fabric material to improve aesthetics and feel of the CAM device. Methods of preparing and applying the CAM device to a user's skin are also provided, as are other aspects.

Continuous analyte monitoring devices and systems having a long-life reusable wireless transmitter unit and application methods therefor

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.

Base units, transmitter units, wearable devices, and methods of continuous analyte monitoring

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.

Wearable continuous analyte measurement devices, biosensor inserters, and methods of use

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.

Biosensor inserters and methods with reduced medical waste

A flexible circuit board for a continuous analyte monitoring (CAM) device includes a plurality of physically separate circuit board cells each having circuitry thereon. The flexible circuit board also includes a plurality of flexible interconnections each connecting one of the physically separate circuit board cells to another of the physically separate circuit board cells. Each one of the flexible interconnections is operable to couple power, electrical signals, or both to the physically separate circuit board cells connected thereto. The flexible circuit board is bendable in multiple directions in three dimensions. Methods of constructing flexible circuit boards for CAM devices are also provided, as are other aspects.
