Abstract: A biosensor inserter includes a push member with a push element, a contact member including a latch, a transmitter carrier supporting a transmitter and sensor assembly, and a pivot member having a latch end, the pivot member supporting an insertion device during biosensor insertion. In operation, the push member is telescoped axially by the user relative to the contact member, which is provided in contact with a user's skin. This pushes the push element against the pivot member and translates the transmitter carrier during insertion of the biosensor. During a first portion of a stroke of the insertion device, insertion of the biosensor is accomplished, and the pivot member is prevented from pivoting. In a second portion of the stroke, after latch end moves past the latch, the pivot member is allowed to pivot and the insertion device is retracted. Other system and method embodiments are provided.

Abstract: 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.

Abstract: An apparatus for inserting a continuous analyte monitoring transmitter that includes an outer member, an inner member configured to telescope relative to the outer member, a transmitter, a bias member, an insertion device, and a pivot member. Force is applied to press the outer member toward an insertion site over the duration of a stroke. During a first portion of the stroke, the pivot member cannot pivot and the motion of the outer member translates to the insertion device until the biosensor is inserted at the insertion site. Over a second portion of the stroke, the continued motion causes a first pivot window in the outer member to overlap with a second pivot window in the inner member, allowing the pivot member to pivot and retract the insertion device from the insertion site, leaving the implanted biosensor.

Abstract: A sensor apparatus for a continuous glucose monitoring system has a sensor housing that includes a first end having a sealing surface configured to seal against an introducer having an insertion shaft, a second end having a sealing surface configured to seal against an insertion shaft cover, and an insertion shaft opening having a width that allows the insertion shaft to travel there through and that extends between the first and second ends. The sensor housing may further include a sensor wire channel that extends between the insertion shaft opening and a sensor wire contact location in an outer surface of the sensor housing. The sensor wire channel and sensor wire contact location may be configured to receive a sensor that extends between the insertion shaft opening and the sensor wire contact location to allow the sensor to make electrical contact to system circuitry. Numerous other aspects are provided.

Abstract: An inserter apparatus (e.g., a continuous analyte monitoring inserter apparatus) includes an outer member; an inner member; a transmitter carrier configured to support a transmitter and biosensor assembly during insertion of a biosensor, the transmitter carrier including a bias member; and a pivot member configured to pivot at times relative to the transmitter carrier and support an insertion device during biosensor insertion. The outer member is configured to press the bias member against the pivot member during insertion of the biosensor. During a first stroke portion of the insertion apparatus, the pivot member is prevented from pivoting. In a second stroke portion, pivoting is allowed, and the bias member causes, pivoting of the pivot member and retraction of the insertion device. Other systems and methods embodiments are provided.
