Abstract: A physiological characteristic sensor assembly includes a flexible top housing including a needle port having a central opening, and a flexible lower housing defining a sensor bore through the lower housing, the sensor bore coaxial with the central opening of the needle port. The physiological characteristic sensor assembly also includes an electrical subsystem disposed between the top housing and the lower housing. The electrical subsystem includes a flexible printed circuit board having a sensor contact pad, a physiological characteristic sensor and an electrically conductive adhesive patch. The physiological characteristic sensor has a distal end that extends through the needle port and a proximal end that includes at least one electrical contact. The conductive adhesive patch electrically and physically couples the at least one electrical contact of the physiological characteristic sensor to the sensor contact pad of the flexible printed circuit board.

Abstract: Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Abstract: A sensor set is provided for sensing of a body characteristic, such as glucose. The sensor set includes a mounting base for the sensor including a shim adapted to prevent pull up of the sensor and a connector to connect to the mounting base and has an improved structure for connecting the mounting base to the connector. The connector may contain sensor electronics for wired or wireless communication to an external monitor or display. The mounting base includes latch arms and the connector adapted to fit and lock into latch recesses on the connector and includes anti-rotation arms adapted to fit into anti-rotation arm recesses on the connector.

Abstract: This disclosure generally relates to medical devices that include a transmitter assembly positioned on top of a sensor assembly. A sensor assembly includes a sensor base having a bottom surface and a top surface having an interface. The interface accommodates a sensor stack that includes at least one sensor head having electrical contact pads connected to an elastomeric connector. The sensor assembly further includes a mounting base having a first side that attaches to the bottom surface of the sensor base, and a second side that adheres to a patient's skin. A transmitter assembly includes a transmitter shell and a transmitter cap having an interface that engages with the sensor base. Also, the transmitter assembly includes electrical contacts disposed on the transmitter cap that connect with the electrical contact pad(s) of the sensor assembly.

Abstract: An improved sensor set is provided for sensing of a body characteristic, such as glucose. The sensor set includes a mounting base for the sensor and a connector to connect to the mounting base. The connector may contain sensor electronics for wired or wireless communication to an external monitor or display. The mounting base includes a connector fitting adapted to fit into a tubular recess in the connector, wherein the connector fitting includes a key. In some embodiments, the proximal end of the sensor folds around the key such that there are contact pads on both sides of the key. The mounting base and connector include additional features, such as pegs and prongs that allow for unique fitting of compatible mounting bases and connectors, while locking out non-compatible components.
