Abstract: 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.

Abstract: 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.

Abstract: Fluid infusion systems such as a wearable fluid infusion device devoid of a user interface includes a housing configured to accommodate a fluid reservoir. The housing has a largest and a smallest dimension. The wearable fluid infusion device includes a drive system configured to be serially coupled to the fluid reservoir such that a dimension of the drive system and the fluid reservoir is less than or equal to the largest dimension. The wearable fluid infusion device includes a planar battery. The planar battery has a plurality of faces comprising one or more faces having a largest area, and the planar battery is situated such that the one or more faces are parallel to the largest dimension and the smallest dimension. The wearable fluid infusion device includes a means for coupling the housing with an adhesive plate configured to couple the wearable fluid infusion device to a user.
